A SIMULATION MODEL FOR THE LIFETIME OF WIRELESS SENSOR NETWORKS

In this paper we present a model for the lifetime of wireless sensor networks. The model takes intoconsideration several parameters such as the total number of sensors, network size, percentage of sinknodes, location of sensors, the mobility of sensors, and power consumption. A definition of the life time ofthe 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. AMatlab based simulator is developed for the introduced model. A number of wireless sensor networksscenarios are presented and discussed.
