Abstract:
In WSN, most existing mechanism around data gathering and optimal path selection result in collision.
Collision further increases the possibility of packet drop. So the need is to eliminate collision during data aggregation. This
research is an effort to come up with a reliable and an energy efficient Wireless Sensor Network (WSN) routing protocol. To
find the rendezvous point for optimal transmission of data a â€œSplitting treeâ€ technique is employed in tree-shaped network
topology and then to determine all the subsequent position of a sink the â€œ Biased Random Walkâ€ model is used. In case of an
event, the sink gathers the data from all the source, when they are in the sensing range of rendezvous point. Otherwise relay
node is selected from its neighbor to transfer packets from the rendezvous point to sink. The proposed routing protocol
simulation results proves there is significant improvement in preventing data collision and increase in the network lifetime
compared with other routing protocol.
