Wireless communications suffer from the problem of interference, where undesired signals reach the destination and cause its performance to degrade. Several mechanisms have been proposed over the last years to mitigate the interference problem, where Coordinated Multipoint (CoMP) outstands as one of the best approaches to tackle the interference in cellular systems. The main disadvantage of CoMP is the need of high signalling over the system in order to exchange information among the different parties involved in the communication process (eNBs and UEs), that questions its practical benefit for the operators. This paper presents a novel beamforming mechanism that needs for very low signalling among the transmitting base stations, it is a low complexity transmission strategy, the amount of interference to cell edge users is controlled and it offers an outstanding performance. Computer simulations show the data rate enhancement of the proposed CoMP mechanism.
无线通信受到干扰的困扰,当不需要的信号到达目的地并导致其性能下降时。在过去的几年里,已经提出了几种机制来缓解干扰问题,其中协调多点(CoMP)是解决蜂窝系统干扰的最佳方法之一。CoMP的主要缺点是需要在系统上进行高信号传输,以便在参与通信过程的各方(enb和ue)之间交换信息,这对运营商的实际利益提出了质疑。本文提出了一种新的波束形成机制,该机制对发射基站之间的信号要求很低,传输策略复杂度低,对小区边缘用户的干扰量可控,具有优异的性能。计算机仿真结果表明,所提出的CoMP机制提高了数据速率。

Enhancing safety messages dissemination over 802.11p/DSRC 加强透过802.11p/DSRC传送安全讯息

Direct radio-based vehicle-to-vehicle (V2V) communication can be used to prevent accidents and to provide accurate information on road state or surrounding vehicles intention. Both kinds of information can be used to enable drivers to react in time and avoid hazardous situations. While the IEEE 802.11p standard has specifically been adopted for vehicular communications, its Distributed Coordination Function (DCF) operation can cause poor delivery rates when the communication channel is congested or when messages need to be transmitted over distances higher than 300 meters. In this paper, we propose MORS, a technique for transmission power adjustment to avoid channel congestion, combined with an efficient multi-hop data dissemination scheme. The purpose is to ensure low delays and high delivery rates for V2V communications at distances higher than it would normally be possible with the same effectiveness with 802.11p alone. The power adjustment technique is fully distributed and asymmetrical, and the multi-hop data dissemination scheme is based on a newly designed multi-metric which characterizes the available links capacity. MORS determines, at each hop, the best available link choice to ensure both reliable transmissions and a minimum delivery delay while reducing congestion and network load though adaptive power adjustment. Simulation results confirm the effectiveness of the proposed transmit-power adaptation and multi-hop relaying schemes under various realistic traffic constraints.
直接基于无线电的车对车(V2V)通信可用于预防事故,并提供有关道路状况或周围车辆意图的准确信息。这两种信息都可以用来使司机及时做出反应,避免危险情况。虽然IEEE 802.11p标准已专门用于车辆通信,但当通信信道拥挤或需要在超过300米的距离上传输消息时,其分布式协调功能(DCF)操作可能会导致传输速率低。在本文中,我们提出了MORS,一种传输功率调整技术,以避免信道拥塞,并结合了一种高效的多跳数据分发方案。其目的是确保V2V通信的低延迟和高传输速率,其距离通常比单独使用802.11p具有相同的有效性时要高。功率调整技术是完全分布式和非对称的,多跳数据分发方案是基于一种新设计的多度量,它表征了可用链路的容量。MORS在每一跳确定最佳可用链路选择,以确保可靠的传输和最小的传输延迟,同时通过自适应功率调整减少拥塞和网络负载。仿真结果验证了所提出的发射功率自适应和多跳中继方案在各种实际通信量约束下的有效性。

Cooperative Communication (CC) and Machine to Machine (M2M) networks have recently emerged as promising techniques for improving spectral efficiency and extending network coverage. CC generated significant interest in the research community for optimizing Energy Efficiency (EE) in next-generation networks. However, envisioning CC as an energy-saving solution for M2M networks gives rise to unresolved problems and significant challenges. In this paper, we discuss the enabling technologies for cooperation in M2M networks, the benefits and challenges of employing these technologies and the open research issues. We first provide an overview of each technology for cooperation in M2M networks. We then study the interaction between the cooperation techniques and the M2M energy-efficient networks employing each of these technologies. We also provide the latest standardization activities of M2M communication in LTE-Advanced networks.

OpenRoads or OpenFlow Wireless is an open-source platform for deploying an innovative and realistic strategy for different services in wireless networks. It provides a wireless extension for OpenFlow. It is developed to support existing Wireless Local Area Networks (WLANs) and Worldwide Interoperability for Microwave Access (WiMAX) networks. It can provide several mobility managers and run them concurrently in the network including hard handover, informed handover, n-casting and Hoolock. However, the provided mobility support for flow-based routing, where flows of one source taking different paths through multiple wireless access points or base stations, is not simple and hard to be deployed in the traditional routing algorithms. This paper proposes an intelligent mobility enhancement control and then develops an algorithm to decide which neighbor switches need to be selected for the installation of new flow entries and to allocate the appropriate idle-timeout for the selected switches. The proposed approach provides a simple solution to solve the user mobility problem in wireless OpenFlow environments which can handle the fast migration of user addresses (e.g. IP addresses) between several wireless access points and base stations. This approach leads to improvement in the end users' experience.
OpenRoads或OpenFlow Wireless是一个开源平台,用于为无线网络中的不同服务部署创新和现实的策略。它为OpenFlow提供了一个无线扩展。它的开发是为了支持现有的无线局域网(wlan)和微波接入(WiMAX)网络的全球互操作性。它可以提供多个移动管理器,并在网络中并行运行,包括硬切换、通知切换、n-casting和Hoolock。然而,对于基于流的路由,其中一个源的流通过多个无线接入点或基站采取不同的路径,所提供的移动性支持并不简单,并且难以在传统路由算法中部署。本文提出了一种智能移动性增强控制,然后开发了一种算法来确定需要选择哪些邻居交换机来安装新的流项,并为所选择的交换机分配适当的空闲超时。该方法为解决无线OpenFlow环境下的用户迁移问题提供了一种简单的解决方案,可以处理多个无线接入点和基站之间用户地址(如IP地址)的快速迁移。这种方法可以改善最终用户的体验。

Small cell deployments are seen as a promising solution for mobile operators due to their potential to improve coverage and increase capacity for indoor areas in a cost-efficient way. Meanwhile, other deployment scenarios are also being sought, such as in public transportation vehicles including buses and streetcars. In this paper, we propose a novel History-based Offloading Framework (HOF) to relieve overburdened macro networks from data traffic generated by mobile users in public transportation vehicles by utilizing small cells and Wi-Fi networks. A small base station (SBS) is installed onboard the vehicle; called a mobile SBS (mobSBS). Mobile users communicate with the mobSBS instead of the distant Macro base station (macroBS). In order to have efficient offloading in terms of bandwidth utilization, mobile data users are prioritized according to different pre-set classes. Our framework takes into account the mobile user's priority and service history to alleviate the effects of non-incessant Wi-Fi availability in order to maximize the offloaded macrocell data traffic. Extensive simulation results have shown that our proposed framework is highly effective in terms of the average offloaded macroBSs data traffic and the total count of offloaded users from the macroBSs.
对于移动运营商来说,小型蜂窝部署被视为一种很有前途的解决方案,因为它们有可能以经济高效的方式改善覆盖范围并增加室内区域的容量。与此同时,也在寻求其他部署方案,例如公共交通工具,包括公共汽车和有轨电车。在本文中,我们提出了一种新的基于历史的卸载框架(HOF),通过利用小蜂窝和Wi-Fi网络来减轻公共交通车辆移动用户产生的数据流量对宏网络的负担。一个小型基站(SBS)安装在车辆上;移动SBS (mobSBS)。移动用户与mobSBS通信,而不是与远处的宏基站(macroBS)通信。为了在带宽利用率方面实现高效的分流,移动数据用户按照不同的预先设置的类别进行优先级排序。我们的框架考虑了移动用户的优先级和服务历史,以减轻非连续Wi-Fi可用性的影响,以最大限度地卸载宏蜂窝数据流量。大量的仿真结果表明,我们提出的框架在平均卸载的macroBSs数据流量和从macroBSs卸载的用户总数方面是非常有效的。

A framework for massive access and radio resource management in urban WLANs 城市无线局域网中大规模接入和无线电资源管理的框架

The challenge in future unlicensed wireless networks will be the coordination of spectrum access among wireless LAN (WLAN) nodes in high dense areas. New WLAN standards, such as IEEE 802.11ah, will provide optimized outdoor WLAN coverage with a range of 1 km, thus exceeding the number of associated WLAN nodes. Hence, massive access schemes are required in order to coordinate the wireless access among WLAN nodes and to mitigate mutual interference. In addition, various wireless networks will co-exist, such as WLANs and sensor networks, competing for channel access. Hence, a framework in order to coordinate WLANs and sensor networks in dense areas is essential. This paper is intended to outline the challenges of wireless access in urban WLANs and proposes a framework which considers the challenges of dense wireless access and discusses potential solutions. The contributions are twofold. A clustering framework is proposed to deal with the massive access of wireless nodes, in particular of IEEE 802.11ah WLAN nodes. Further, a radio resource monitoring and management (RRMM) is proposed to manage the co-existence among wireless networks. A novel system architecture is proposed and discussed in order to monitor and manage the WLAN access in highly dense urban areas.
在高密度区域,无线局域网(WLAN)节点间频谱接入的协调将是未来无证无线网络面临的挑战。新的WLAN标准,如IEEE 802.11ah,将提供优化的户外WLAN覆盖范围为1公里,从而超过了相关WLAN节点的数量。因此,为了协调无线局域网节点间的无线接入并减少相互干扰,需要大规模的接入方案。此外,各种无线网络将共存,如无线局域网和传感器网络,争夺信道接入。因此,为了协调密集区域的无线局域网和传感器网络,一个框架是必不可少的。本文概述了城市无线局域网中无线接入的挑战,提出了一个考虑密集无线接入挑战的框架,并讨论了潜在的解决方案。贡献是双重的。针对无线节点,特别是IEEE 802.11ah无线局域网节点的海量接入,提出了一种聚类框架。在此基础上,提出了一种无线资源监控与管理(RRMM)系统来管理无线网络间的共存。提出并讨论了一种新的系统架构,以实现对高密度城区无线局域网接入的监控和管理。

New WLAN standards, such as IEEE 802.11ah, will provide optimized outdoor WLAN coverage with a range of 1 km, thus exceeding the number of associated WLAN nodes. Hence, massive access schemes are required in order to coordinate the wireless access among WLAN nodes and to mitigate mutual interference. In addition, various wireless networks will co-exist, such as WLANs and sensor networks, competing for channel access. Hence, a framework in order to coordinate WLANs and sensor networks in dense areas is essential. This paper is intended to outline the challenges of wireless access in urban WLANs and proposes a framework which considers the challenges of dense wireless access and discusses potential solutions. The contributions are twofold. A clustering framework is proposed to deal with the massive access of wireless nodes, in particular of IEEE 802.11ah WLAN nodes. Further, a radio resource monitoring and management (RRMM) is proposed to manage the co-existence among wireless networks. A novel system architecture is proposed and discussed in order to monitor and manage the WLAN access in highly dense urban areas.","PeriodicalId":290924,"journal":{"name":"38th Annual IEEE Conference on Local Computer Networks - Workshops","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128406654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wireless Sensor Networks (WSNs) are rapidly gaining popularity in various critical domains like health care, critical infrastructure, and climate monitoring, where application builders have diversified development needs. Independent of the functionalities provided by the WSN applications, many of the developers use visualization, simulation, and programming tools. However, these tools are designed as separate stand-alone applications, which force developers to use multiple tools. This situation often poses confusion and hampers an efficient development experience. To avoid the complexity of using multiple tools, we have designed a new extensible, multi-platform, scalable, and open-source framework called PROVIZ, which is an integrated visualization and programming framework. In this paper, we explain the various features of PROVIZ's visualization and programming framework and discuss how PROVIZ can be used as a visual debugging tool to aid in providing a software fix.
无线传感器网络(wsn)在医疗保健、关键基础设施和气候监测等各种关键领域迅速普及,应用程序构建者在这些领域具有多样化的开发需求。与WSN应用程序提供的功能无关,许多开发人员使用可视化、仿真和编程工具。然而,这些工具被设计为独立的应用程序,这迫使开发人员使用多个工具。这种情况经常造成混乱并妨碍有效的开发体验。为了避免使用多种工具的复杂性,我们设计了一个新的可扩展的、多平台的、可伸缩的和开源的框架,称为PROVIZ,它是一个集成的可视化和编程框架。在本文中,我们将解释PROVIZ可视化和编程框架的各种特性,并讨论如何将PROVIZ用作可视化调试工具来帮助提供软件修复。
