Reducing Transmission Energy of Sensor Node for Enhancing Lifetime of the Wireless Sensor Networks

Abstract

Network lifetime has turned out to be the important thing for comparing sensor networks in a utility precise manner. In wireless sensor networks, the sensor nodes are powered by small batteries; hence, the strength consumption in working a WSN should be as little as possible. The wireless sensor community present all sensor nodes generate an equal amount of statistics packets in a WSN, nodes around a sink should relay more packets and have a tendency to die earlier than other nodes due to the fact that the energy intake of sensor nodes is nearly absolutely dominated by means of data communication in place of sensing and processing. Therefore, the overall network lifetime can be improved by balancing the communication load at heavily loaded nodes around a sink. This problem is one of the most important issues for WSNs. At present, the heterogeneity of networks and a fair cooperative routing method is analyzed. To avoid unfair improvement only on certain networks, we introduced one or a few shared nodes that can use multiple channels to relay data packets. The sinks and shared nodes can communicate with any WSNs node, different WSNs can use cooperative routing with each other since shared nodes allow sensor nodes to forward data from another WSN as the function of interchange points among respective WSN planes. However, still the sensor nodes in the wireless sensor network facing energy consumption problem. To avoid this problem in this journal we are implementing energy saving method in wireless sensor network. We can observe the reduced transmission energy simulation results of the energy saving on NS2 simulator.
