In this paper, focus is on energy aware model of wireless sensor networks in which each sensor node randomly and alternatively stays in an active or sleep mode. The active mode consists of two phases, the full-active phase and the semi-active phase. When a particular sensor node is in the full-active phase of the active mode, it may sense data packets, transmit the sensed packets, receive packets, and relay the received packets. However, when the phase of the sensor node switches from the full active phase to the semi-active phase, it is only able to transmit/relay data. When the particular sensor node is in a sleep mode, it does not interact with any other node. In this work, emphasis is also given on numerical analysis for energy aware model. An energy aware model for WSN is being also developed with active and sleep features and justified with mathematical analysis and results thereon.
