摘要:

针对无线传感器网络周期性全局快速数据收集应用场合,提出了一种新的基于粒子群优化和禁忌搜索的混合算法,以对这类网络进行多指标TDMA优化调度。该算法采用基于熵权的逼近理想解的排序法对算法结果进行客观评价和择优。当网络数据收集任务量一定时,应用该算法,只需要较少的时隙数和能耗便可完成任务。仿真结果证实,算法搜索效率高,能改善网络TDMA调度效果,且比已经提出的一些TDMA调度算法性能优越。

Abstract:

A novel hybrid algorithm based on particle swarm optimization and tabu search is proposed for multi-objective optimized TDMA scheduling in the applications for wireless sensor networks which require periodic global data snapshots, and weighted entropy based technique for order preference by similarity to ideal solution is introduced to evaluate and choose the result of the algorithm objectively. When the amount of data collection tasks of the network is constant, it needs only fewer slots and energy expenditure to complete them by using the algorithm. Simulation results validate that the proposed scheme has a highly search efficiency and can improve the effect of the TDMA scheduling on wireless sensor networks and outperforms compared with that of other algorithms.
