Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF RANDOMIZED REVERSE AD HOC ON DEMAND DISTANCE VECTOR ROUTING PROTOCOL IN MANETK. Santhi, B. ParvathavarthiniIn high mobility, routing in Mobile Ad-Hoc Network is a very difficult task. In AODV and RAODV, all the data packets are travel through the same shortest path so the intruders can easily trace out the data path. The main objective of Randomized RAODV provides the multipath and then the paths are selected randomly for security purposes. Using randomized routing … …Journal of Computer Science, Vol. 10, Issue 9 · 30 Apr 2014 · 6,809 accessesView PDFCite

Research ArticleOpen accessIn the abstractMESSAGE AUTHENTICATION CODE BASED SECURE GROUP KEY MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKST. Peer Meera Labbai, V. RajamaniA mobile ad hoc network is a group of nodes which are communicating with each other with the use of radio frequencies. When there is high movement of mobile nodes, the nodes find difficult to reach other nodes. If the data are exchanged between nodes when there is high mobility, the data may be lost in transit. Therefore the security … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractCluster Based Time Division Multiple Access Scheduling Scheme for Zigbee Wireless Sensor NetworksB. Meenakshi, P. AnandhakumarIn IEEE 802.15.4 ZigBee Wireless Sensor Networks, an efficient scheduling mechanism is required for reliable data transmission. Further, concurrent transmission of huge data through CSMA/CA incurs more packet collision rate. This complicated condition has to be eliminated to improve the system throughput. In this study, we propose to deploy cluster based TDMA scheduling mechanism for IEEE 802.15.4 ZigBee Wireless Sensor … …Journal of Computer Science, Vol. 8, Issue 12 · 26 Nov 2012 · 6,682 accessesView PDFCite
