摘要:

在多要素无线监控网络中,涉及图形、图像、视频等要素的采集和传输,而传统的传感网络路由在这种高负载的网络中表现出性能上的不足。为了高效地传输监控信息,针对这一网络中多路径路由进行优化设计,提出利用梯度导向的启发式信息来指导路由路径的建立,从而提高路径建立的能效。同时,针对监控节点分布的稀疏和稠密两种情况,提出基于梯度信息的贪婪式转发路径创建算法GBGF和基于梯度信息的受限广播路径创建算法GBRB。模拟结果显示,基于梯度思想的引入对多径路由的能效有极大的提高。

Abstract:

The multi-factor wireless monitoring network involves the collection and transmission of graphics, images,video,and other elements.Traditional sensor network routing in high load networks shows a lack of performance. In order to improve energy efficiency, the multi-path routing for such network is designed and optimized, and it is proposed that gradient oriented heuristic information is used to guide the establishment of the routing path, thus improving the energy efficiency of path establishment. Meanwhile, for both sparse and dense monitoring node distribution, the greedy forwarding path creation algorithm based on gradient information GBGF and the limited broadcast path creation algorithm based on gradient information  GBRB are proposed. The simulation results show that multi-path routing based on the gradient can greatly improve the energy efficiency.
