Choosing a routing protocol is an essential part in the success of the communication in mobile Ad-Hoc networks (MANET), since their topology is constantly changing. In many MANET applications (such as rescue tasks applications) it is necessary to assure reliable communication among network nodes. In this paper is showed a performance evaluation of two reactive routing protocols in order to know which is the most appropriate one for rescue tasks operations. Two protocols are evaluated: AODV (Ad hoc On Demand Distance Vector) and DYMO (Dynamic MANET On-demand routing protocol). Various mobility conditions in the environment are presented as well as the respective behavior of the protocols under these variations. The results of this work are organized in metrics which enabled the conclusions about the protocols performance.
由于移动自组织网络(MANET)的拓扑结构是不断变化的，路由协议的选择对通信的成功与否至关重要。在许多MANET应用(如救援任务应用)中，必须保证网络节点之间的可靠通信。本文对两种响应路由协议进行了性能评价，以确定哪一种协议最适合救援任务操作。评估了两种协议:AODV (Ad hoc On Demand Distance Vector)和DYMO (Dynamic MANET On Demand routing protocol)。提出了环境中的各种移动条件以及在这些变化下协议的各自行为。这项工作的结果被组织在指标中，从而得出关于协议性能的结论。

Communication in Mobile Ad-Hoc Network (MANET) is based on mutual trust between the participating nodes. Due to features of open medium, dynamic changing topology, lack of centralized monitoring and management, MANETs are vulnerable to various security attacks. Hence, finding a secure and trustworthy end-to-end path in MANET is a real challenge. The paper presents a solution for trustworthy path discovery in MANET that comprises of an effective reputation based trust management scheme through cross-correlation of monitored traffic and a trust based routing protocol that dynamically evaluates trustworthy path. Our analysis shows significant improvement in packet delivery ratio of AODV in the presence of attacks, with marginal rise in control traffic overhead.

Web service failures or degradations directly cause operational inefficiencies and financial losses in Web service-based business processes (WSBP). In today’s competitive Web service market a considerable number of functionally-similar Web services offered by different providers are differentiated by competitive QoS levels and pricing structures. Consequently, dynamic and optimal Web service selection is a significant challenge to business organizations which run such WSBPs. Having a cost-effective and efficient Web service selection approach is becoming an important necessity for such organizations. Current Web service selection approaches offer "one-size-fits-all"; solution, i.e., one optimal service selection for all running BP instances. However, such solutions are neither efficient nor cost-effective given that the service levels of WSBPs are associated with customers classes/profiles, e.g., Gold, Silver or Bronze. Therefore, we propose a group-based Web service selection approach, "one-size-does-not-fit-all", that optimizes multiple QoS criteria and differentiate the service selection based on the BP customers classes/profiles. Our approach shows a very good improvement over existing "one-size-fits-all" approaches; 65% average cost reduction and 30% utility value improvement.

Dynamic spectrum management is the key technology in cognitive radio network, of which the first task is spectrum sensing. So spectrum sensing plays an importance role in cognitive radio network. In this paper a new spectrum sensing algorithm is proposed, which is based on compressive sensing (CS) and multitaper method combined with singular-value decomposition (MTM-SVD) to estimate frequency spectrum and detect spectrum hole. The new algorithm is validated by the data from GSM network, and simulation results show that the new algorithm can achieve good detection performance and afford reduced sampling rate.

In this paper, we propose the Network Service Platform (NSP), which is a framework to develop network services using real-world data efficiently, and implement its application. We implemented a prototype system based on NSP using GPS data and image data obtained from cell phones. This service integrates internet services with ubiquitous services by using the Robot Service Network Protocol (RSNP), an open standard protocol for robot services. Through the implementation of the prototype system, we confirm the effectiveness of NSP to develop network services.

Raw materials for generating energy and producing goods are not always extracted where they are needed, namely in the sphere of man settlement. It is likely that growing numbers of workers are required to work in remote habitats. Being in such rural conditions is a costly, complex and difficult undertaking for both, the companies and their labour force. The Smart Camp project merges several challenges that we face nowadays. It aims to address the high expenses and emissions from off-grid energy generation. Furthermore, finding a work-life balance and dealing with the concomitant everyday problems in a remote area results in human social and psychological issues. This project also aims to use digital convergence technologies and techniques in order to deal with these challenges. This paper reports the status quo of research that has been done in this area and gives and introduction to the project.

Mobile devices are now equipped with multiple sensors and networking capabilities. They can gather information about their surrounding environment and interact both with nearby nodes, using a dynamic and self-configurable ad-hoc network, and with distant nodes via the Internet. While the concept of mobile agent is appropriate to explore the ad-hoc network and autonomously discover service providers, it is not suitable for the implementation of strong distributed synchronization mechanisms. Moreover, the termination of a task assigned to an agent may be compromised if the persistence of the agent itself is not ensured. In the case of a transactional mobile agent, we identify two services, Availability of the Sources and Atomic Commit, that can be supplied by more powerful entities located in a cloud. We propose a solution where these two services are provided in a reliable and homogeneous way. To guarantee reliability, the proposed solution relies on a single agreement protocol that orders continuously all the new actions whatever the related transaction and service.

In this paper, we propose a network-engineering (NE) approach for improving the availability of light paths over WDM networks. By rearranging the availability of links, the average availability of light paths can be improved without sacrificing performance in terms of blocking probability and investing extra capital expenditures (CAPEX) and operational expenditures (OPEX).

Currently the user’s web search is disjoint from the resources which is subsequently browsed. Specifically the related instances of the search are not displayed on the following pages. This lack of continuity between the actual search and the web sites displayed may lead to skimming by the user to identify what is relevant on the pages. This paper presents an approach to the continuous modeling of a user’s interests through a browser based plug-in that may be used to inform the intelligent highlighting of content on the browsed pages. Specifically the paper presents two related systems, one for capturing and modeling the user’s browsing behavior and the second for leveraging the power of linked data to highlight information relevant to the user’s interests. The design, implementation and evaluation of both systems are presented as well as a conclusion and outlook for further work.

In the MAC protocols based on the S-MAC scheme, usually the combination of periodic sleep/listen scheduling and four-way handshake mechanism is employed to reduce idle listening and avoid interference. However, this combination greatly degrades network capacity and results in high end-to-end latency. In this paper, we propose Adaptive IAMAC to increase channel utilization and improve communication efficiency, specifically in large-scale sensor networks with low duty cycle. Adaptive IAMAC allows multiple nodes to transmit to their common parent during a frame. Moreover, it includes the adaptive parent selection mechanism, which enables the nodes to change their parent according to the currently overheard control packets at the MAC layer. Through these techniques, Adaptive IAMAC enhances network throughput, reduces end-to-end latency, and moderates the overhead of four-way handshake mechanism. Simulation results confirm that Adaptive IAMAC provides significant improvements over S-MAC in terms of throughput, latency, and energy efficiency.
