摘要

Wireless networks equipped with CSMA are sch eduled in a fully distributed manner. A disadvantage of such distributed control in multihop networks is the hidden node problem, which causes the effect of stealing, in which a downstream node steals the channel from an upstream node with probability p. Aziz, Starobinski, and Thiran [IEEE/ACM Trans. Networking, to appear] have recently shown that the N-hop model with stealing is stable only in the case N = 3 and p ∈ (0, 1]. This 3-hop model can be represented as a random walk in the quarter plane. We derive various asymptotic expressions for the stationary large buffer probabilities of the 3-hop model that capture the effect of p. We mainly rely on the ray method, and we show how this method is related to the compensation approach and singularity analysis.
