ELECTROSTATIC FIELD BASED RELIABLE ROUTING IN WIRELESS SENSOR NETWORKS USING VECTOR METHOD

Routing in Wireless Sensor Networks (WSN) is very challenging, due to several characteristics that distinguish them from existing communication and wireless ad-hoc networks. Data forwarding technique in Wireless Sensor Networks (WSN) is analogous with the motion of an electric charge in an electrostatic field. Shortest path routing does not guarantee to enhance the network lifetime and power-aware routing may increase the number of hops between the source and destination node. To trade-off between these two methods, our proposed vector projection approach gives the successful delivery of packets. From the definition of electromotive force (emf) of a battery, we are calculating the projection of attraction force along the line joining between source and destination node due to nodes positioned in the forward direction of propagation. Selecting the node as the next sink node having the capability of forwarding the maximum times of successful packet forwarding.
