基于移动网关的大规模无线传感网能耗均衡技术研究

In order to resolve the energy hole problem of large-scale wireless sensor networks (WSNs), the project makes full use of mobile cellular networks (MCNs) base stations (BSs) and mobile sink gateways to solve the energy balancing for large-scale WSNs. At the theoretical layer, the project research focuses on the WSN nodes adaptive access control algorithms based on the mobile sink gateway level and the MCN-assisted cluster load dynamic balancing algorithms. At the same time, the project will research the adaptive power-control broadcast routing algorithms for different service types. According to the mobile sink gateway two-way data mapping of communications, the project establishes the communication model between MCNs and WSNs based on the service traffic, service level, transmission reliability, and constructs system cross-layer energy consumption model with the mobile sinks for large-scale WSN, which considers the WSN node's optimal transmitting power, the residual energy, the type of service to optimize the WSN nodes access and transmitting routing algorithm in order to make the WSN system energy consumption more balanced. Finally, at the experimental verification layer, this project builds a system simulation platform to verify and optimize the theoretical research results based on a actual physical simulation environment, which achieves the balance of energy consumption for large-scale WSN system. The research results of the project can extend the WSN life time, promote the convergence development and complement for MCN and WSN.
