针对特定应用场合的混合型拓扑控制算法是WSN拓扑控制领域的研究热点之一。在深入研究经典的面向事件驱动型网络拓扑控制算法—ASCENT基础上,提出了一种自适应的混合型拓扑控制算法—AHTC算法。它针对大规模事件驱动型网络场景应用,解决了ASCNET算法不能适应于大规模网络、未考虑节点剩余能量、网络丢包率高等问题。仿真结果表明,改进的算法有更好的节能性和稳定性。
Hybrid topology control algorithm for specific applications is one of the hot issues in the field of WSN topology control. On the basis of the study of classical-oriented event-driven network topology control algorithm-ASCENT, an adaptive hybrid topology control algorithm-AHTC is proposed. Solve the problems of ASCNET when applying to network scenes of large-scale driven-event. The problems such as failure adaption in large scale network, less consideration of node residual energy and high rate of network packet loss. Simulation results show that the improved algorithm has better energy efficiency and stability.
