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.
