Research ArticleOpen accessIn the abstractImpulse Radio Ultra Wide Band Based Mobile Adhoc Network Routing Performance AnalysisM. Sreedhar, C. VenkateshThis study presents with the routing overhead analysis of impulse radio - Ultra Wide Band based wireless networks which Employs Dynamic Nature Routing (EDNR) method for determining and selecting the stable route in Mobile Adhoc Network (MANET). This method requires only two sample packets and uses piggyback information on Route-Request (RREQ) and Route-Reply (RREP) packets during a route-discovery procedure. Conventional … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 15 Apr 2013 · 5,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractSleeping Cluster based Medium Access Control Layer Routing Protocol for Wireless Sensor NetworksT. Nagamalar, T. R. RangaswamyWireless sensor networks play a vital role in remote area applications, where human intervention is not possible. In a Wireless Sensor Network (WSN) each and every node is strictly an energy as well as bandwidth constrained one. Problem Statement: In a standard WSN, most of the routing techniques, move data from multiple sources to a single fixed base station. Because … …Journal of Computer Science, Vol. 8, Issue 8 · 16 Jul 2012 · 6,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractRealization of Fault Tolerant Routing Protocol for ZigbeeSharmila Sankar, SankaranarayananProblem statement: Increased use of handheld devices and sensor devices pose problems in existing routing protocols. The performance of the existing routing protocols deteriorates very much on these dense scenarios. Control overheads are very important parameter in deciding the performance of routing protocols, which are introduced during route discovery and maintenance process. Denser the network, higher is the control overhead … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Distributed Coverage and Target Tracking Algorithm for Wireless Sensor NetworksM. Senthamilselvi, N. DevarajanProblem statement: Due to communication, processing and energy constraints, tracking in sensor networks creates different challenges. Since existing algorithms utilized the information from all the sensors for tracking, it results in higher expenditure of energy and reduced lifetime for the network. Approach: We propose to develop a distributed coverage and target tracking algorithm for wireless sensor networks. Tracking issue is … …Journal of Computer Science, Vol. 8, Issue 3 · 6 Jan 2012 · 6,698 accessesView PDFCite
