In this paper, different control channel (CC) implementations for multichannel medium access control (MAC) algorithms are compared and analyzed in the context of opportunistic spectrum access (OSA) as a function of spectrum-sensing performance and licensed user activity. The anal

Abstract¿Personal Networks (PN) is a concept in the area of
modern communication networks in which devices belonging to
a person cooperate to offer services to the person regardless of
their geographical locations. A PN may consist of several adhoc
sub-networks (or clusters) whic

Ad-hoc networks, fundamental properties and network topologies provides an original graph theoretical approach to the fundamental properties of wireless mobile ad-hoc networks. THis approach is comined with a realistic radio model for physical links between nodes to produce new i

In this paper we propose a new model to calculate interference levels in wireless multi-hop ad-hoc networks. This model computes the expected value of Carrier to Interference ratio (C/I) by taking into account the number of nodes, density of nodes, radio propagation aspects, mult

In this paper we study connectivity in wireless ad-hoc networks by modelingthe network as an undirected geometric random graph. The novel aspect in our study is that for finding the link probability bwtween nodes we use in a radio model that takes into account statistical variati
