This study aims to develop a Trust Value Based Intrusion Detection System (TIDS) to identify and prevent Denial of Sleep attacks (DoSL) in Wireless Body Sensor Networks (WBAN). To detect and deter DoSL attacks, this IDS employs pre-distributed random keys, random passwords, the trust value of each node, node energy consumption, and an agent database. Since sending and receiving information packets within the network consumes the energy of the sensors, adopting an appropriate and optimal method to reduce energy consumption and efficient routing selection is necessary. The proposed framework uses Genetic Algorithm (GA) to select the optimal Cluster Head (CH) and the Ad-hoc On-demand Distance Vector (AODV) routing protocol for intra-cluster routing. This work simulates two attack scenarios: one in the presence of IDS and one in its absence, to understand the efficiency and effectiveness of IDS. In both scenarios, we measure and compare various network parameters such as throughput, network lifetime, Packet Delivery Rate (PDR), and node residual energy. We also benchmark TIDS against one of the recent highly cited works, “Secure and energy-efficient framework using Internet of Medical Things (IoMT) for e-healthcare (SEF-IoMT)”, against all network parameters listed above. The simulation results and their comparison with the benchmark study show that the proposed method could significantly improve the network parameters in deterring DoSL attacks. This study uses NS2 for running all tests and experiments.

The MPTCP Transport Layer protocol allows applications to make use of multiple network interfaces simultaneously, allowing for improved throughput and resilience. MPTCP deploys a number of coupled congestion control algorithms that couple congestion window growth across multiple subflows. This restricts window growth to allow competing TCP flows to attain a fair bandwidth share. We examine the performance of existing algorithms across both shared and disjoint paths, finding that these function reasonably only when the bottleneck is shared and the paths exhibit a low bandwidth-delay product. We then propose using uncoupled congestion control within MPTCP, instead managing fairness within the network using SDN. Experimental validation shows that this approach results in fair sharing across shared and disjoint paths, including those with higher bandwidth-delay products.

The Software Defined Networking (SDN) paradigm has the potential to improve the operation and efficiency of the global Internet. In recent times, SDN has been extensively adopted in data centres and business networks. Recently, more research is being carried out to find solutions to the problems caused by the continually increasing complexities of the SDN. Issues regarding the lack of transparency between SDN domains impact security, so peer authentication is required. Peer authentication remains a critical issue. SDN domains are linked by the routing protocol Border Gateway Protocol Version 4 (BGP4). To improve the transparency of BGP4 transactions, this paper proposed a Blockchain-based BGP4 Orchestration (BBO) framework that utilises an Internet number resource authority and trustworthy management entity. BBO provides an origin advertisement source and has been found to outperform Resource Public Key Infrastructure (RPKI) in terms of securing origin advertisement and establishing a required setting for the resource repository. This research work ensures sufficient deployment incentives for SDN based federations.
软件定义网络(SDN)范式具有改善全球互联网运行和效率的潜力。近年来，SDN已被广泛应用于数据中心和业务网络中。近年来，人们正在进行更多的研究，以寻找解决SDN不断增加的复杂性所带来的问题。关于SDN域之间缺乏透明度的问题会影响安全性，因此需要对等身份验证。对等身份验证仍然是一个关键问题。SDN域之间通过路由协议BGP4 (Border Gateway protocol Version 4)连接。为了提高BGP4交易的透明度，本文提出了一种基于区块链的BGP4编排(BBO)框架，该框架利用互联网号码资源权威和可信赖的管理实体。BBO提供了一个源发布源，并且在保护源发布和为资源存储库建立所需设置方面优于资源公钥基础设施(Resource Public Key Infrastructure, RPKI)。这项研究工作确保了对基于SDN的联盟有足够的部署激励。

Job dispatching appears in many communication and computer systems. In this paper, we present a classification of dispatching policies according to their scalability, and introduce the class of sequential dispatching policies. These, highly scalable policies are a special case of index policies. By means of numerical examples, we show that efficient, practically optimal, dispatching may be achieved by a sequential policy, or a simple dynamic variant of such a policy, under heavy load. These numerical examples suggests that efficient and scalable load balancing can often be realized by simple primitive dispatching elements amenable also for machine learning based approaches.

Android malware detection is an important foundation for guaranteeing the security of Android ecosystem. Convolutional neural network has been applied in Android malware detection. It usually requires a large amount of training samples for building an efficient model. However, the malware data collection costs much time and resources. The lack of training samples may lead to overfitting problem. In addition, the model may become ineffective when the data distribution is significantly changed. To handle these problems, this paper proposes a new malware detection method. It firstly trains a model on an initial training set using convolutional neural network. With the upcoming of more samples, the model is updated by fine-tuning the pre-trained model on the newly labeled data. So that the pre-trained model could be dynamically updated. The experiments on the real datasets show that our method can further improve the accuracy and gmean about 1.3% and 2.4% respectively on average.

Applications of fiber bragg gratings (FBG) in optical communication are a growing area. Recently, there has been a lot of interest in the creation and use of chirped FBGs, which are distinguished by a non-uniform modulation of the refractive index within an optical fiber core. Chromatic dispersion (CD) in pulse broadening and inter symbol interference (ISI) at the light detector significantly affect high-speed optical networks. The wavelength range where optical fibers have a low transmission loss is where fiber-optic communication is mostly carried out. Five wavelength bands make up this low-loss wavelength zone, which has a range of 1260 to 1625 nm. In this study we compared three different optical bands with different chirped FBG lengths to tackle the chromatic dispersion compensation containing 10 Gbps data speed. The single-mode fiber length and quality factor (Q) are minimally improved by the combination of four UFBG and CFBG design technique. By implementing quality factor (Q) of the available SMF are improved by using the combination. The best results have been seen for correcting chromatic dispersion by implementing quality factor (Q) of the available SMF are improved by using the combination. We consider Q-factor, eye diagram, and BER as a performance indicator of the system.

Preventing the exfiltration of critical data via out-of-band channels is one of the most difficult challenges in cybersecurity. This challenge notably includes commu-nications utilizing optical channels. Numerous papers have suggested the modulation of indicator lights to transmit information out of otherwise secure networks. These means of optically embedding data are both challenging to detect and a threat to the security of confidential data. This paper presents a scalable, near-real-time process to detect and localize data hidden in optical channels amid other optical modulation, including electric network frequencies. Assumptions on the detectability of hidden optical channels are reviewed and a method of detecting and localizing transmissions based on spectral artifacts of embedded data is developed. Proof-of-concept experiments demonstrate the successful detection of potential optical data leaks in an office environment. This capability can allow for low cost optical bug sweeping devices, arming information security teams with a tool to detect and mitigate the insidious threat of optical out-of-band channels.

The ongoing demand for deploying Virtual Network Functions (VNFs) in cloud environments is driving the motivation to also deploy and enable Service Function Chaining (SFC). However, deploying SFC in a cloud environment includes multiple subproblems such as implementing an SFC-compatible infrastructure, routing design, placement, and scaling. We believe the deployment of SFC-compatible infrastructures and the routing design issues need further attention as they are fundamental constituents of SFC-enabled cloud environments. In this paper, we present a new flexible SFC framework using a multi-nodes Kubernetes cluster, a Software-Defined Networking (SDN) controller, and an OpenFlow-enabled virtual switch known as Open vSwitch (OvS) to deploy and steer the user traffic to a distributed SFC. We demonstrate the correctness of the proposed SFC framework by monitoring the OvS flow table on Kubernetes worker nodes.

This paper considers video and audio transmission in ICN (Information-Centric Networking) CCN (Content- Centric Networking), in which each intermediate node can cache content. LCE (Leave Copy Everywhere) has been known as a generic cache decision policy. However, because LCE caches at all the intermediate nodes, the cache of intermediate nodes can be duplicated. Therefore, various cache decision policies that eliminate redundancy have been proposed. In this paper, we evaluate the effect of the cache decision policies on QoE of video and audio transmission in ICN/CCN. We assess application-level QoS using a computer simulation with a tree network and QoE by means of subjective experiment.

To allow 5G deployments in challenging environments and for special use cases like 5G radio positioning, authorities reserve a part of the radio spectrum for privately owned campus networks. Such deployments require a characterization of the communication channel in the specific environment to fit to application requirements. This paper presents results on a channel sounding measurement series in an industrial environment. The sounding approach, based on 5G wideband downlink test signal channel estimation, only uses widely available equipment and may serve as a template for easy but efficient channel sounding in such environments. The arriving measurement results give some insights on special challenges regarding network coverage and radio positioning in industrial environments.
