Item Energy efficient node-disjoint multipath route discovery mechanism for wireless sensor networks(2011) Shiva Murthy, G.; D'Souza, R.J.; Varaprasad, G.To increase the operational lifetime of the wireless sensor network is the major objective of energy efficient routing protocols. Mutlipath routing protocols enhance the lifetime of the wireless sensor network by distributing the traffic among multiple paths instead of single optimal path. This Work proposes a low control overhead route discovery mechanism for Energy Efficient Node-disjoint Multipath Routing Protocol. The number of control messages used in the route construction is minimized. The energy spent on the route discovery mechanism is also minimized. © 2011 Springer-Verlag.Item Reliability analysis of route redundancy model for energy efficient node disjoint multipath routing in wireless sensor networks(Elsevier Ltd, 2012) Shiva Murthy, G.; D'Souza, R.J.; Varaprasad, G.The objective of every sensor node in a sensor network is to send the sensed data in the phenomena to the sink node. Many routing protocols select an optimal path to increase the network lifetime in sensor networks. The consumption by the nodes along this optimal path is high, thereby causing their early death. In the multipath routing, path reliability is high, because of the availability of alternate paths to the optimal paths. This work proposes a theoretical frame work to study the reliability analysis of route redundancy model for node disjoint multipath networks in wireless sensor networks. The reliability of route redundancy in single path and multiple paths with varied number of nodes and its probability values are discussed. © 2012 Published by Elsevier Ltd.
