DRP: Dynamic Routing Protocol in Wireless Sensor Networks

Routing is the process of identifying the best path from source to sink nodes. The lifetime of nodes in the network is crucial and has to be increased by considering energy of the node. In this paper, Dynamic routing protocol is proposed to improve the Quality of Service by increasing the lifetime of the Wireless Sensor Networks. When a node requires sending the data, it searches for an intermediate node. It is assumed that nodes in network must have the equal sensing range, identical speed and also same energy. The forwarding node is selected by parameters such as the number of hops towards the sink, remaining energy and distance towards the sink node. The source or intermediate node considers itself as located in the origin and divides the area into four quadrants. The nodes that are in the sink quadrant are conceived as eligible forwarding nodes. One of the nodes is selected and used to forward data packet towards the sink. The proposed method performs better than the other existing methods.
