By providing the potential for high connectivity speeds, this technology has led to a dramatic rise in the number of access points (APs). In such environments, mobile devices have the choice to join several Wi-Fi networks. Despite its importance to user Quality of Experience (QoE), the AP selection is still trivial since it focuses at best on the received signal strength if not only the user's history. Crucial metrics that capture the overall dynamics of the AP load condition, such as the network load, are not taken into account. In this paper, we propose to use the Busy Time Fraction (BTF) as a metric to choose the best AP to attach to. The BTF level of a given channel is inferred based on the frame aggregation scheme proposed since the 802.11n standard. In this regard, we propose an analytical model based on a Discrete-Time Markov chain that discerns the theoretical DownLink aggregation levels for probe traffic concurrent to cross traffic. We validate the accuracy of our proposed approach against ns-3 simulations under several scenarios.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80288103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mirabedini","doi":"10.32908/ahswn.v53.7989","DOIUrl":"https://doi.org/10.32908/ahswn.v53.7989","url":null,"abstract":"Vehicular Ad-hoc Networks (VANETs) are a set of mobile nodes that move on the road and connect via wireless. Due to the limited radio range, they send data to each other by collaborating. Some nodes drop the other nodes’ packets to save the network supplements; therefore, the network’s performance will reduce. So it is necessary to identify selfish nodes to prevent other nodes from cooperating with them. In the proposed scheme, a punishmentbased algorithm is presented to identify the selfish nodes used in Adaptive Resonance Theory (ART) clustering to monitor and control them. The cluster head determines if selfish behaviors occur in the cluster or not. If the cluster head discovers that there is a selfish behavior in the cluster, it begins to check the packets that were sent and received by all nodes. In the proposed method, each node in the network is equipped with learning automata, the probability of selecting each neighbor node to send the packet, which is rewarded or punished according to the performance. Simulation results have shown that the rate of detection of selfish nodes is more than other methods, and the false alarm rate (FAR) is less than other similar methods.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73900197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various types of attacks are prone to damage the networks due to the elastic property possessed by the network. And among different categories of attacks that can affect MANETs, black hole attack is considered as the commonly occurring one within a MANET. Chicken Swarm Optimization (CSO) algorithm is one among the technique used for the detection of black hole attacks occurring in the MANETs. But the CSO algorithm possesses some disadvantages and necessity rises for overcoming the weakness in the CSO algorithm. Objective: Therefore, in this research paper, to address the black hole attack in MANET, an Improved Crossover Chicken Swarm Optimization (ICCSO) algorithm and the concept of Enhanced Partially-Mapped Crossover operation proposed and the best fitness values obtained. Methods: In ICCSO algorithm, parameter initialization is carried out in step 1 of the algorithm, where the attacked nodes and non-attack nodes are created separately with the aid of parameters like PDR (i.e.) Packet Delivery Ratio and RSSI (i.e.) Received Signal Strength Indicator. Further, If the node is affected by any attack, then the nodes are discarded and the data is transmitted through the non-attacked node. Routing is carried by a protocol of AODV.Results: The effectiveness of the algorithm proposed in the work is evaluated using various performance measures like packet delivery ratio (PDR), end-to-end delay (EED) and throughput. The performance measures are compared with a different state of the art routing protocols and it can be inferred that the proposed methodology comes up with improved results.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87689828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Augé","doi":"10.1145/3416011.3424749","DOIUrl":"https://doi.org/10.1145/3416011.3424749","url":null,"abstract":"The 5G (fifth-generation) mobile networks, especially by exploiting higher bandwidth in the mmWave (millimeter wave) spectrum, is the leading candidate to be used as the coming generation for ubiquitous networks. The vast available bandwidth in mmWave can satisfy the high data rate and low latency expectations from 5G networks in order to provide new services and use cases. Although 5G mmWave networks come up with innovative and robust services, they suffer from a drawback. As the frequency rises, the penetration power and coverage area of the network decreases, so it results in having discontinuous communication between a base station and a user. This intermittent characteristic is caused due to an existing obstacle such as a car or a building on the communication path that can hurdle the establishment of a transmission, which is called NLoS (Non-Line of Sight) state. NLoS states can degrade the functionality of the network and prevent from having seamless connectivity by forcing fluctuations in the network's channels. The reason for this shortcoming is because of the susceptibility of high frequencies to the blockage that can be generated by obstacles. The intense negative effect of having a blockage in the network is on an end-to-end communication when other layers protocols such as the transport layer widely used protocol TCP (Transmission Control Protocol) are used. Having frequent disconnections in the network impairs the TCP's functionality with inducing congestion states and preventing it from achieving higher performance. In this paper, we present the performance evaluation and analysis of TCP in different situations in an urban area and find out how various conditions can affect the performance of the protocol. The simulation results indicate that conventional TCPs are not adequate enough to be exploited in 5G mmWave networks. For having them functioning in their full potential, some modifications should be made in order to adapt them to 5G mmWave networks. Some ML (Machine Learning) techniques such as Neural Networks and Reinforcement Learning can be deployed as the key enablers to network performance improvement.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90156573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, channel bonding also limits spacial reutilization and complexifies channel assignment. In this paper, we present a fast and efficient solution for channel width selection and channel assignment in 802.11 WLANs using channel bonding. The proposed algorithm uses a novel, graph-centric metric to propose a single channel width for all the APs of the WLAN aiming at avoiding starvation in any of the network's APs. Decoupling the choice of channel width and channel assignment results in a scalable approach that bypasses the usual complexity issues of classic channel assignment schemes. We test the solution's precision in choosing a suited channel width and assignment by comparing its results with those delivered by the ns-3 network simulator. We obtain that, in the large majority of the cases, the choice made by our solution matches the simulation results.","PeriodicalId":55557,"journal":{"name":"Ad Hoc & Sensor Wireless Networks","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75821666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
