多次重传的链状无线传感网络可靠性分析
Analysis of reliability for wireless sensor network with chain topology based on multiple retransmission strategy
摘要
Abstract
To solve the problem that multi-hops decrease the reliability in wireless sensor network with chain topology, the reliability indexes such as link reliability,energy availability for nodes,instantaneous reliability and average time without failure are presented and analyzed.The models of composite channel fading and energy for sensor nodes are established. Based on the established models,theoretical expressions of the relevant reliability index are derived.Based on the analysis on energy imbalance between the nodes, the program of initial energy is distributed.The simulation results verify the correctness of the theory.It provides a new theoretical support for analysis on the reliability of wireless sensor networks and reliability assessment or prediction.关键词
