摘要
针对目前大多数拓扑控制算法忽略节点间通信干扰的问题,提出一种更为合理的节点间通信干扰的定义方法,并在此基础上提出具有低干扰特点的拓扑控制算法。仿真结果表明,该算法能在保证连通性的前提下,减小节点的通信半径,减少生成拓扑中的冗余通信链路,降低节点之间的通信干扰。
Topology control is one of the most important techniques in wireless sensor network,and also one of the hottest research topics.However,most topology control algorithms fail to take communication interference into account.In this paper,a more practical definition of communication interference is introduced first,and then a new topology control algorithm is proposed.At last simulation and analysis is given,which shows by careful choosing the communication range of nodes,redundant communication links can be significantly reduced and communication interference can be minimized,meanwhile the network's connectivity is not jeopardized.
