QoS Route Discovery Method With Implementation Of Best Energy For Wireless Sensor Networks

The wireless sensor networks (WSN), composed by sensors, microprocessor and wireless communication interface, is a multiple-hop and self-organized networks. The research of WSN has attracted lots of attentions because of its wide applications in resent years.Since WSN is characterized by its limited battery-supplied power, extensive research efforts have been devoted to the design of efficient power saving policy to increase its lifetime.In order to overcome the negative factors due to the natural characteristics of WSN, we present a new quality of QoS route discovery method which could guarantee the requirement of QoS and has better network lifetime. The method utilizes the node selection system and node's neighbor table to construct the set of candidate node in which the node's left bandwidth meet the requirement of the mission. So the number of the node which is supposed to be detected will reduce. In order to maximize the WSN's lifetime, the genetic algorithm (GA) utilizes the energy estimate model and node energy consumption weight model which are constructed to adaptive deal with the nodes's scheduling problem in WSN. The simulations and the analysis show the choosing interval of the controlling parameters proposed by the GA. The experiment results show the QoS route discovery method with the implementation of best energy for WSN has better adaptability and longer lifetime.
