Research ArticleOpen accessIn the keywordsSSM: Slot Scheduling Mechanisms in a Multihop Wireless Hotspot NetworkMaan Younis AbdullahOur focus was to determine a "slot" time for message forwarding. To this end, we model the system as a "Queue" where the time for packet forwarding is determined by slot, at different slot range for each relaying node. We also introduced one important reason of the poor performance is the close coupling between medium contention and network congestion. Our … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,449 accessesView PDFCite
Research ArticleOpen accessIn the keywordsADOPEL: ADAPTIVE DATA COLLECTION PROTOCOL USING REINFORCEMENT LEARNING FOR VANETSAhmed Soua, Hossam AfifiEfficient propagation of information over a vehicular wireless network has usually remained the focus of the research community. Although, scanty contributions have been made in the field of vehicular data collection and more especially in applying learning techniques to such a very changing networking scheme. These smart learning approaches excel in making the collecting operation more reactive to nodes mobility … …Journal of Computer Science, Vol. 10, Issue 11 · 22 Jul 2014 · 8,418 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact of Sybil and Wormhole Attacks in Location Based Geographic Multicast Routing Protocol for Wireless Sensor NetworksShyamala Ramachandran, Valli ShanmuganProblem statement: Wireless sensor networks have been used in many applications, such as home automation, military surveillances and entity tracking systems. The sensor nodes have low computational capabilities and are highly resource constrained. Routing protocols of wireless sensor networks are prone to various routing attacks, such as black hole, rushing, wormhole, Sybil and denial of service attacks. Approach: The objective … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,988 accessesView PDFCite

Research ArticleOpen accessIn the keywordsA New Distance Based Route Maintenance Strategy for Dynamic Source Routing ProtocolMuhammad F. Sjaugi, Mohamed Othman, Mohd. Fadlee A. RasidAlthough DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from the route cache. If alternative routes are not available, the source node, then, will enter route discovery phase to find new routes. We introduced a new … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,316 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Enhanced Associativity Based Routing ProtocolSaid A. Shaar, Fawaz A.M. Masoud, Ayman Murad et al.This study introduces an analysis to the performance of the Enhanced Associativity Based Routing protocol (EABR ) based on two factors; Operation complexity (OC) and Communication Complexity (CC). OC can be defined as the number of steps required in performing a protocol operation, while CC can be defined as the number of messages exchanged in performing a protocol operation[1].

Research ArticleOpen accessIn the keywordsPerformance Evaluation of Modified AODV for Load BalancingAmita Rani, Mayank DaveAODV is a prominent routing protocol for MANET that uses hop count as a path selection metric. However, AODV has no means to convey traffic load on current route. This study focuses on introducing a new metric, Aggregate Interface Queue Length (AIQL), in AODV in order to deal with load balancing issues. Performance evaluation through simulation shows that the modified … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the abstractProposing a Hybrid Topological Organization for Non-Misbehaving Nodes with Optimal Path Selection Using Game-Theoretic ApproachKanmani S, M. MuraliIn dynamic communication networks, improvement of energy efficiency is one of the major challenges for reliable communication. By considering this challenge, we focus to develop the topology of the network. In this study, we design a hybrid star-mesh topology for minimizing the latency as well as energy consumption of the network. In the hybrid network topology, the Ad-Hoc On-Demand Multipath … …Journal of Computer Science, Vol. 19, Issue 10 · 31 Aug 2023 · 5,401 accessesView PDFCite
