matlab code for simulate energy consumption in wsn

Wireless sensors have received increased attention in the past years due to their popularity and cost effectiveness when they are used in harsh environments. They have been used in many applications including military applications, environmental applications, health applications, and home applications. Although they are very cost effective and easily deployed in harsh environments, they are limited by the power available through their life cycle. Sensors are usually deployed with limited power which is depleted over their lifecycle. Once their power is depleted, the sensors become dead and they are no more useful. An evaluation of the life cycle of a wireless
sensor network is very essential to estimate how long a network can live and when the network and its sensors might be replaced or recharged if possible.
