摘要

The paper addresses the performance analysis of the fixed-window CSMA media access protocol with the geometric probability distribution of choosing the slot within the contention window. This scheme, called Sift, was initially proposed for large-scale wireless sensor networks. The primary benefit of geometric CSMA is high channel utilization for broad range of numbers of contending nodes. The goal of the present paper is to compute the standard performance measures of geometrically distributed slotted-CSMA both in the context of data-centric dense sensor networks and node-centric industrial automation networks. The stochastic analysis of the throughput/channel utilization, the collision rate and the mean access delay is carried out. Finally, the protocol performance is compared with some conventional CSMA schemes with uniform distribution.
