Energy Modeling of ML-MAC Wireless Sensor Network Protocol

Abstract

It is well recognized that a proper energy consumption model is a foundation for developing and evaluating a power management scheme in the wireless sensor networks (WSN). Duty Cycle is a prominent mechanism for achieving energy efficiency in wireless sensor networks (WSNs). For this purpose, current WSN MAC (Medium Access Control) protocols use duty cycle schemes, where they consciously switch a node's radio between active and sleep modes.The contribution of this paper is twofold: First, a theoretical energy model based on simple finite automata is presented. This model can be used for simulation and generation of ML-MAC with duty cycle variation. Second, the proposed theoretical model is backed up by simulation measurements using QualNet 6.1 Thereafter; output of the theoretical model and simulated results are compared and validated.
