Abstract

In this paper we present a model for the lifetime of wireless sensor networks that incorporates the effect of the communications model. The model takes into consideration several parameters such as the total number of sensors, network size, percentage of sink nodes, location of sensors, the mobility of sensors, power consumption when nodes move and the power consumption of the communications circuitry. A definition of the lifetime of the network based on three different criteria is introduced; percentage of available power to total power, percentage of alive sensors to total sensors, and percentage of alive sink sensors to total sink sensors. A Matlab-based simulator is developed for the introduced model. A number of wireless sensor networks scenarios are presented and discussed.
