Research ArticleOpen accessAll words, across the recordAn Analysis and Overview of Wireless Routing ProtocolsN. Dhanalakshmi, P. AlliProblem statement: In the past, the main focus of the research in the wireless network is to provide optimal routes between source and destination nodes. The wireless routing is required additional computational effort than wired routing in order to fulfill the major wireless characteristics such as battery power constraints, frequent mobility and less processing. Approach: In addition to wired routing … …Journal of Computer Science, Vol. 8, Issue 3 · 17 Jan 2012 · 7,628 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImpact 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 · 6,982 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Improved Location aided Cluster Based Routing Protocol with Intrusion Detection System in Mobile Ad Hoc NetworksS. Mangai, A. TamilarasiProblem statement: Routing and security are the main challenges for ad hoc networks due to dynamic topology as well as resource constraints. A designed protocol must provide scalable routing with better security. Lack of any central coordination and shared wireless medium makes them more vulnerable to attacks than wired networks. And also resource constraints such as limited energy and size … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,103 accessesView PDF Cite
