基于能量与功率控制的TopDisc拓扑算法研究

拓扑控制是无线传感器网络的一个重要研究方向,选择良好的拓扑控制机制,能够提高网络通信效率并延长网络的生命周期。在TopDisc算法的基础上,提出了一种基于能量与功率控制的拓扑控制算法,在能量的引导下,通过调整节点的发射功率,生成更适合的网络拓扑结构。仿真实验结果表明改进的算法形成的簇的交叠更少,网络的生存时间更长。

TopDisc Topology Algorithm Based on Energy and Power Control

Topology control is an important researching direction in wireless sensor networks. Selecting a good topology control mechanisms is good for improving the efficiency of network communication and prolonging the life cycle of net- work. Based on TopDisc algorithm, this thesis proposes a topology control algorithm based on energy and power control, which can generate a more suitable network topology through adjusting nodes transmission power under the guidance of the energy, Simulating results show that the improved algorithm can form the less overlap of the clusters and survival time on the net may become longer.
