Achieving Scalable Performance in Large-Scale IEEE 802.11 Wireless Networks
Overview In large-scale wireless networks, interferences among nodes limit channel spatial re-use and are a main hurdle for scalable performance. There are two types of interferences: physical interferences due to the receiver's inability to decode a signal when the powers received from other signals are large; and protocol interferences imposed by the specific multi-access protocol being used. This paper models interference types 1 and 2 in terms of a set of inequality constraints for the IEEE 802.11 CSMA/CA protocol. Based on the inequalities, it investigates the impact of the parameters basic-rate, data-rate, and physical-preamble-rate, on channel spatial re-use.
