Wireless Sensor networks (WSN) consist of tiny sensor nodes which are having limited processing power, memory, battery and communication capabilities. WSN differs from traditional networks in several ways: sensor nodes have severe energy constraints, redundant low-rate data and many-to-one flows. In order to enhance the lifetime of the node, many algorithms were proposed in the literature to reduce the energy consumption of the node. Taking the routing decision based on the energy or modifying the duty cycle of the node can obtain this objective. If these energy based algorithms are developed and tested in a well-known simulators like ns2, OMNETT++ etc, the energy estimation is not a prime criteria, since these simulators are having well defined energy models. While implementing these algorithms in real motes like MICA, IRIS etc., estimating the energy consumption is a big task. The effectiveness of these algorithms is based on how efficiently the residual energy of the system is calculated at run time. In this work, we explore the various methods used for estimating the residual energy of the real mote. Based on the previous work, we propose a method for estimating the energy of the WSN mote IRIS from Crossbow Technologies.
