摘要
无线传感器网络拓扑控制算法对于延长网络的生存时间、减小通信干扰、提高路由协议和MAC协议的效率等具有重要的意义。在分析XTC(eXemplary Topology Control)算法的基础上,提出一种改进的基于局部网络信息的分布式拓扑控制算法M-XTC(Modified-XTC)。改进算法保持了XTC算法简单、实用,不需要节点位置信息,适用于普通节点、异构网络和三维空间等优点,并且更有利于延长网络的生存时间,具有更好的实时性和鲁棒性。
Topology control algorithms for wireless sensor networks are significant for prolonging the network lifetime, reducing radio interference, increasing the efficiency of routing protocols and MAC protocols, among other things. Based on the analysis of the XTC (eXemplary Topology Control) algorithm, this paper proposed a modified local distributed topology algorithm M-XTC (Modified-XTC). The modified algorithm maintains the advantages such as simple, practical,available without node position information, applicable for nodes without special instruments, heterogeneous networks, three-dimensional space networks as the XTC algorithm does. Moreover, it is also more conductive to prolong the network lifetime,and has much more real-time and robustness.
