Abstract
In this dissertation a new comprehensive model for the lifetime of Wireless Sensor Networks (WSNs) in different environments is presented. 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, and power consumption. Furthermore, the model considers the power consumed in the electronic circuitry, the data size, the probability of transmission or receiving of data, and the distance of transmission. A number of wireless sensor networks scenarios are presented and discussed. In order to examine the validity of the model, it is tested for many scenarios. Furthermore, it is validated against the simulations results of Micaz sensors. In this dissertation, several scenarios in the air, water, and soil are presented. In each scenario, the total power in the network, number of dead sensors, total number of alive sensors, and number of dead sinks nodes over the lifetime of the WSN are evaluated. The new model addresses the following issues: (1) study the effect of communications on the lifetime of Wireless Sensor networks, (2) present an advanced model of power consumed in communications and its effect on the lifetime of Wireless Sensor Networks, (3) develop a new model for the Lifetime of Wireless Sensor Networks in both pure water and salty water communication, and (4) develop a model for the lifetime of the wireless sensor network communications in different types of soil including, sandy, loamy and magnetite soil. The results obtained from the model are accurate compared to the results of the Micaz simulation. The results presented in this model show its importance from the designer perspective. The model can be used as a design tool as well as a research tool to evaluate the performance of the wireless sensor networks.
