无线传感器网络节点活动时间协调优化策略

Optimized Strategies Approached for Time Scheduling in Wireless Sensor Networks

在分析无线传感器能量有效性和状态周期时间策略的基础上,通过建立合理的基于单个节点的周期状态工作模型的功耗和时间分布策略,以及着眼于网络完整性的节点间时间协调工作分配的理论模型,来探讨在网络中进行节点内的时间分配以及节点间的时间水平和功率分配的最佳组合边界,得出了有益的结论.

This paper is based on the premise that the powerefficiency and time-scheduling of wireless sensor networks would be optimized. Analytical models are established on the performances about the time scheduling of both the nodes themselves and their coordination which aims to enhance the network integrity. The optimal frontier of the portfolios that comes from nodes power consummation and time-power tradeoff are presented by utilizing the mean-variance model. Hereafter, the paper presents the heuristic conclusions involved in the arrangement of time-scheduling, keeping the network equilibrium, and making full use of the power endowment.
