摘要
通过对蚁群算法(ACO)的研究,设计了一种适合无线多媒体传感器网络的路由协议.该算法模拟自然界蚂蚁群体在寻找路径的方式,在节点发送数据包时,以该路径之前发送数据包的频率以及通过该路径的代价为参数,计算选择该节点为下一跳的转发概率.仿真结果表明,采用该算法时,节点的平均寿命要比采用传统的定向投递算法时的节点寿命高20%,数据包成功发送速度也远远高于传统算法.
This paper proposes a routing algorithm by using the ant colony optimization that is applicable to WMSN.The algorithm simulates the means of ant colony finding their ways in nature.One node calculates the probability to choose next hop to send package on the basis of the frequency used prier to this route and the cost through this path.The experimental results show that,compared with traditional direct diffusion algorithm,the average service life lengthens by 20%,and the speed of successfully sending packages is much higher by using the proposed algorithm.
