Abstract:This paper is based on the premise that the powerefficiency and timescheduling 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 timepower tradeoff are presented by utilizing the meanvariance model. Hereafter,the paper presents the heuristic conclusions involved in the arrangement of timescheduling, keeping the network equilibrium, and making full use of the power endowment.
