节点信息重要程度耦合能耗联合判断机制的WSN关键点裁决算法
WSN key point decision algorithm based on node information importance degree and energy consumption joint judgment mechanism
摘要
Abstract
Since the key point decision of the available wireless sensor network (WSN) has unified decision indicator and complex decision process,and it is difficult to improve the insufficient of data transmission and convergence performance in the region,a new WSN key point decision algorithm based on node information important degree and energy consumption joint judg-ment mechanism is proposed. The hierarchical relationship among the wireless sensor nodes and node information important de-gree are used to realize the information interaction of current node and neighbor node. The node information is acquired to esti-mate and calculate the criticality of the whole network,and obtain the numerical character value. According to the energy con-sumption level of current node and correlation between current node and underlayer node,the energy consumption joint judg-ment mechanism was designed. In combination with the energy consumption increment of node sending data and numerical charac-ter value,the key point decision factor is acquired. The sensor network key point is judged accurately with sorting. The results of simulation experiment show that,in comparison with the available WSN key point decision algorithm,the proposed algorithm mined more key point quantity for decision,reduced the performance influence on network operation and network congestion oc-currence time,and improved the whole bandwidth utilization of network data aggregation and stable running time.关键词
