Analysis of the lifetime of wireless sensor networks for underground communications in dry sand

In this paper we present an advanced model for power consumption in communications and study its effect on the lifetime of the wireless sensor networks in underground communications for dry sand. The power communications model is incorporated in the life time model of wireless sensor networks. The life time 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 communications. The model for power consumption in communications shows more accurate results about the lifetime of the sensor network in comparison with previously published results.
