Improved Topology Control Algorithm for Wireless Sensor Networks
一种适用于无线传感器网络的拓扑控制算法

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.
