Maximum lifetime broadcast tree construction algorithm based on particle swarm optimization in wireless ad hoc networks using directional antennas
针对无线自组网中在使用单波束定向天线情况下的最大生命期广播路由问题,提出一个基于粒子群优化的最大生命期广播树构造算法.在该算法中,粒子位置表示一棵广播树,粒子适应度值为粒子位置所表示的广播树的生命期.该算法在粒子群执行搜索的过程中采用多种措施提高求解质量和效率.在更新粒子位置时对新粒子位置进行限制以保证节点的生命期不低于某个阈值.利用EPUS-PSO的粒子群体管理策略根据解的搜索状态动态地增减粒子,利用EPUS-PSO的解信息共享策略使每个粒子可…查看全部>>
To solve the maximum lifetime broadcast routing problem in wireless ad hoc networks where each node is equipped with single-beam directional antennas, a maximum-lifetime broadcast tree construction algorithm based on particle swarm optimization is proposed. In this algorithm, each particle position represents a broadcast tree, and the particle fitness is the lifetime of the broadcast tree represented by the particle position. During the searching process of …查看全部>>
