Energy Efficient Routing (EER) For Reducing Congestion and Time Delay in Wireless Sensor Network

A Wireless Sensor Network (WSN) has sensor nodes which highly scalable and limited storage capability nodes. In the network, the nodes are in distributed manner and autonomous devices. The sensor node can communicate the information directly or indirectly. In WSN, the packets should be routed from source to destination within the limited power storage. The sensor nodes of WSN are highly mobile and based on the dynamic scenarios in the routing path and the network topology change frequently. A node in the routing path should be aware of the information regarding the nearest node. In traditional routing protocols, every node in the network exchanges periodic one-hop beacons. Beacons are short messages send periodically to indicate the neighbor nodes about their identification and position in the network. In the existing approach, some problems may occur during the data forwarding. Hence to overcome those problems Energy Efficient Routing (EER) approach is proposed in this paper. In the proposed modelling, the new algorithm named Discrete Delay Function (DDF) is introduced. In that algorithm, RTS/CTS message handshaking mechanism is used for data forwarding. By using this mechanism, the existing approaches' limitations can be reduced. Simulation results show that EER scheme significantly outperforms existing protocols in wireless sensor networks with highly dynamic network topologies.
