A Complete Energy Dissipation Model for Wireless Sensor Networks

Advances in both microelectronics and wireless commu- nication technology have made it possible to develop and manufacture low cost and energy efficient sensor nodes. To compare different designs and protocols with respect to both energy and delay constraints an energy dissipation model is needed that takes these aspects into account. In this paper we propose a complete energy dissipation model for wire- less sensor networks that uses four operation states. These states are based on the basic sensor nodes architecture and actual working conditions of a sensor node. It also takes into account the transition between the operation states, such that a decision to change operation state can be more accurately determined. In this paper we also present mea- sured values for both the power consumed in each operation state and the time it takes to complete a transition between two operation states.
