Description: In last decades, the demand of wireless spectrum has
increased rapidly with the development of mobile communication
services. Recent studies recognize that traditional fi xed spectrum
assignment does not use spectrum effi ciently. Such a wasting
phenomenon could be amended after the present of cognitive
radio. Cognitive radio is a new type of technology that enables
secondary usage to unlicensed user. This paper presents an
Opportunistic Cognitive MAC Protocol (OC-MAC) for cognitive
radios to access unoccupied resource opportunistically and coex-
ist with wireless local area network (WLAN). By a primary traffi c
predication model and transmission etiquette, OC-MAC avoids
producing fatal damage to licensed users. Then a ns2 simulation
model is developed to evaluate its performance in scenarios with
coexisting WLAN and cognitive network.-In last decades, the demand of wireless spectrum has
