Research On The Energy Conservation Protocol Of Wireless Sensor Network

The nodes in wireless sensor networks energy is supplied by the battery, the energy is very limited. Therefore, we need to design more energy-efficient wireless sensor network protocols to support the operation of the network as much as possible to extend the effective lifetime of the current study to become one of the hotspots. This wireless sensor networks to extend the effective lifetime of the issues the following two aspects:Firstly, this paper analyzes and discusses SMAC protocol for Wireless Sensor network (WSN). Aiming at the problem of can not be based on data size in wireless sensor network to self-adaptive dutycycle. This improved scheme will take more time to listen and improve the throughout when the data flow in network is large, and will take more time to sleep when the data flow in network is small.Secondly, we analyzes DSR routing procotol for Wireless Sensor network (WSN). Based on DSR routing protocol, we proposed a new improved scheme. Aiming at the problem of DSR procotol only consider the minimum hops between the source node and the destination node, without considering the energy problom, We propose a new improved scheme: When a node's energy is exhausted, it will automatically send a request package to the source node. This package includes the address and the node residual energy. After the source node receives this packet, will update the route cache table, and according to the number of hops for each route and the remaining energy to re-select the best route.The results of the simulation indicates that the improved protocol improves on energy conservation, load balancing, delay.
