Dynamic Task Allocation Algorithm with Parallel Alliance in Wireless Sensor Networks
Zhanghui Liu · Journal of Chinese Computer Systems · 2012
Due to the characteristics of wireless sensor networks(WSNs),such as dynamic change of the load,the paper proposes the concept of the parallel alliance of WSNs,and designs the algorithms of discrete particle swarm optimization based parallel alliance and over-demanding.The algorithm allocates several tasks to some suitable alliances in parallel;at the same time,tracking and adjusting the running condition of WSNs in real-time.The proposed algorithm processes complex or real applications well,and effectively improves the utilization of the resources in WSNs.The simulation results show the effectiveness of the proposed algorithm,and prolong the lifetime of the network in some extent.
