摘要/Abstract

摘要：

目标检测是无线传感器网络中的一种重要应用,文中提出了一种能量有效分布式多传感器目标检测方法,该方法区别于以往的单目标方法,通过多个节点相互协作对目标进行检测,算法1给出了时间序列离散法,求得目标被测距离,且多节点将检测到的信息在聚合节点进行聚合,并通过算法2找到一条最优传输路径将聚合数据包传送至sink节点。此外通过仿真比较了单节点检测目标和多节点协同检测目标的概率、权系数α对检测节点平均能量消耗的影响,并给出了目标检测数据的最佳采样周期。

Abstract:

Target detection in wireless sensor networks is an important application.This paper proposes an energy efficient distributed multi-sensor target detection method using multiple nodes collaboration different from the conventional single-objective approach to target detection.Algorithm 1 shows the discrete time series method,by which the target is obtained by the detected distance and multi-node information of the detected nodes is polymerized.Algorithm 2 finds an optimal transmission of data packet transfer path to the sink aggregate node.A comparison is made between the single node and multi node detection target collaborative detection through simulation of the probability of the target and the weight coefficient for the average energy consumption of the detection node.The optimum target detection data sampling period is given.

Key words: wireless sensor networks;target detection;multi-sensor collaboration
