Interference Pattern Diffusion Mechanism to Enhance the Capacity of IEEE 802.11 Ad Hoc Networks
Abstract
This work presents an efficient method for interference pattern reporting in wireless ad hoc IEEE 802.11 networks. The information disseminated can be used by neighboring terminals to adjust transmission parameters so as to increase spatial reuse. We simulated the operation of ad hoc networks, in which the intensity of the interference produced by close communication is monitored in a set of terminals. The results show that the variation of received interference in time, under certain conditions, corresponds to transitions between values belonging to a finite set, with the addition of a series of residuals. The proposed method is basically to transmit the interference pattern received through the periodic dissemination of this set of values and their relative occurence rate. Thus, it is possible to transmit to the neighboring terminals a summary of the interference received by the terminal of interest, without sending the entire time series collected, minimizing the overhead required.References
