In this paper we study a novel distributed rendezvous protocol for cognitive radio networks (CRNs), which is based on a grid quorum system, hence we call it the gQ-RDV protocol. A paper tackles with an asymmetric channel view problem rarely investigated due to its complexity. Hence, the objective of the paper is twofold. Different grid-based quorum(More)
— IEEE 802.11 [1] has become the standard for Wireless LAN's both in infrastructure and in ad hoc mode. The standard specifies the medium access control mechanism, Distributed Coordination Function (DCF). Deploying the 802.11 DCF in wireless multi-hop networks leads to inefficient utilization of bandwidth and energy due to many unnecessary collisions. To(More)
