Research On Energy Efifcient Technology In Wireless Sensor Networks Based On Energy Harvestinnd Low Duty-cycle Optimization

Wireless Sensor Network is composed of multitudinous sensor nodes which havespecific acquisition function, and the energy it carries determines its continuousworking ability, this is the embodiment of node’s life cycle. Therefore, the energymanagement of sensor nodes appears particularly important.This paper realizes a kind of energy-saving design using solar sensor nodes. Itdoes research into the MPPT algorithm model of solar node, and presents a nodeenergy adaptive control algorithm particularly suitable for disaster weather andconducting simulation experiments. The results show that the algorithm has a goodeffect. For solve low duty ratio under the way of delay limit problem, this paper putsforward a kind of based on tabu search heuristic optimization algorithm which canmaintain the complex network of E2E delay, simulation results show that its DelayMaintenance performance is better than the Delay Maintaince. In order to solve thepoor-quality link and energy-constrained network delay problems, this chapterproposes a MC-Streamline deferred maintenance program to protect waiting delayfrom Sink node to a specific node. Simulation and experimental results show that theMC-Streamline has the best delay protection performance among the Single Streamlineand the Muti-Streamline.Delay constraint protocal currently evaluates only in the Matlab simulationplatform, and the simulation results have certain one-sidedness. The next major work isto verify the effectiveness of the protocal in actual node.
