无线Ad Hoc网络中保留最小能量路径的拓扑控制算法

提出一个分布式的拓扑控制算法，通过改变节点的传输功率，该算法产生的无线网络拓扑结构具有最小能量特性，即它保留了网络中任意一对节点之间的最小能量路径．该算法不仅适用于同质的无线Ad Hoc网络，而且也适用于异质的网络．仿真研究表明，提出的算法在平均节点度和传输功率的效率方面均优于基于直接传输区域的拓扑控制算法．

Study of the minimum-energy path-preserving topology control algorithm for wireless Ad Hoc networks

We propose a distributed topology control algorithm for constructing a wireless network topology with the minimum energy property, namely it preserves a minimum-energy path between every pair of nodes. Moreover the proposed algorithm can be used in both the homogenous and the heterogeneous wireless networks. Simulation results show that the proposed algorithm has advantages over the topology control algorithm based on the direct-transmission region in terms of average node degree and power efficiency.
