Abstract
The topology control can improve the performance of ad hoc networks,the topological connectivity of beam forming antennas in multihop wireless networks is more complicated than topologies for wireless networks with omni-directional antennas. This paper proposes a local optimal topology control algorithm for ad hoc networks based on steered beam directional antennas. This kind of algorithm uses the idea of cluster to divide the network into a number of areas which can be overlapped. Through running the local Minimum Spanning Tree(MST) algorithm,the neighbourship of nodes in areas is confirmed. Regulating the transmission power of nodes and changing the directional antenna's direction,beam width and gain,topology can be built. It reduces the average node degrees and the transmission power, thus energy consumption is reduced,traffic interference is decreased and the network throughput is improved. The result of simulation shows that this algorithm significantly improve the network performance.关键词
