TopDisc algorithm for topology control research based on dump energy

在保证无线传感器网络连通性和覆盖度的前提下,通过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。在分析TopDisc算法的基础上引入能量剩余,得出一种改进的TopDisc算法,并对算法进行仿真,结果表明:改进的算法在网络的生存时间上要长于原算法,在节点剩余能量上比原算法更平均。

Under the promise of ensuring the network connectivity and coverage, by selecting a good topology control mechanism, the efficiency of network communication is improved and the life cycle of network is prolonged. Based on the analysis algorithms of TopDisc algorithm, an improved algorithm of TopDise is introduced to inject the surplus of energy into the algorithm. Through the analysis and comparison of the two results, conclusion are drawn that on the one hand, the network survival time of improved algorithm is longer than the original algorithm. On the other hand, the dump energy of nodes by improved algorithm are more even than the original algorithm.
