Choosing the channel reservation period in self-organizing wireless networks

Abstract

In order to improve the utilization of channel resources, modern technologies of self-organizing wireless system increasingly use methods of deterministic access, in which the stations preliminary reserve time intervals for packet transmission. To reduce the overhead caused by the distributed reservation of time intervals, these intervals have equal duration and are strictly periodic, i.e., equidistant from each other. Typically, the reservation periodicity is chosen according to the properties of a particular data stream. In the present work, we show that this approach is inefficient and propose a new method in which the periodicity is a multiple of a number called the basic periodicity. Using analytical modeling and simulation we show that the proposed method significantly increases the network capacity.
