【摘要】：随着人们对水环境的日益关注以及无线传感器网络技术的成熟,如何使用无线传感网络对水环境进行监控成为一项重大课题。该文在动态水环境中,基于正方体网格剖分思想提出了一种以熵为尺度来衡量路径稳定性的QoS路由算法(EWSQoS),该算法使用正方体网格对信息收集区域进行剖分,再在此基础上寻找到达Sink节点的最短网格,最后利用"熵"来选择路由,减少了重建路由(或路由修复)的次数,在网络拓扑频繁变化的环境中尽可能地提供QoS保证。经仿真实验与性能分析表明,EWSQOS算法与Long-term、DBR、DTN等算法比较,在路由重建次数、路由成功率、网络能耗、网络延时方面具有更优性能。
[Abstract]:With the increasing attention to water environment and the maturity of wireless sensor network technology, how to use wireless sensor network to monitor water environment becomes an important issue. Based on the idea of cuboid mesh generation, an QoS routing algorithm based on entropy to measure path stability is proposed. The algorithm uses cube mesh to partition the information collection area, and then finds the shortest grid to reach the Sink node. In the end, "entropy" is used to select route, which reduces the number of reconstructing routes (or route repair), and provides QoS guarantee as much as possible in the environment of frequent changes in network topology. The simulation experiments and performance analysis show that the EWSQOS algorithm is compared with Long-termDBRN algorithm. It has better performance in the aspects of route reconstruction times, route success rate, network energy consumption and network delay.
