Abstract

In wireless ad hoc networks broadcasting is a fundamental operation where control information is usually propagated as broadcasts for the realization of most networking protocols. In traditional ad hoc networks, since the spectrum availability is uniform, broadcasts are delivered via a common channel which can be heard by all users in a network. However, in cognitive radio (CR) ad hoc networks, unlicensed users may observe spectrum availability, which is unknown to other unlicensed user before the control information was broadcast. Thus it is extremely challenging that broadcasts can be successfully conducted without knowing the spectrum availability information in advance. In this paper, the performance of a neighbour coverage based broadcast protocol is proposed using different QoS metrics such as packet delivery ratio, end -to-end delay, packet loss probability and network control overhead.
