Abstract

The standardized IEEE 802.11 Distributed Coordination Function (DCF) provides a contention-based distributed channel access mechanism for mobile stations to share the wireless medium. However, when stations are mobile or portable units, power consumption becomes a primary issue since terminals are usually battery driven. In this paper, we propose an analytical model that calculates the energy efficiency of the hybrid of the basic and the RTS/CTS access mechanism of the IEEE 802.11 protocol, assuming that the packet lengths are variable. Validation of our new analytical model is carried out by comparison with simulation results using NS-2 simulation package.
