The exponential growth in wireless services has resulted in an overly crowded spectrum. The current state of spectrum allocation indicates that almost all usable frequencies have already been occupied. This makes one pessimistic about the feasibility of integrating emerging wireless services such as large-scale sensor networks into the existing communication infrastructure. Cognitive radio is the...
This paper examines rendezvous protocols for ad hoc network establishment in cognitive radio networks. Such capability is needed when deploying cognitive radios in an area whose existing fixed communications infrastructure has been destroyed, such as after a natural disaster. A review of previous rendezvous strategies reveals the need for more research and analysis on the multi-channel, asynchronous...
