Abstract

Contention-based bandwidth request (BR) mechanism in wireless networks is suggested for users with ad-hoc connectivity to support best effort services at affordable cost. In this letter, we develop failure aware contention mechanisms when message and code based signaling mechanisms are carried out on a link with three-hop. The stations perform contention with dynamic update of contention window from the model developed through appropriate failure events of a link. Attributes that influence the contention BR are analyzed through the developed model. The proposed model is validated by means of numerical results.
