Abstract :
Reducing the handoff rate and the handoff latency is one of the best ways to minimize performance degradation during cognitive user ongoing communications. In this paper we introduce an algorithm for dynamic channel allocation which is based on the task allocation model in ant colony. We called this algorithm as Channel Allocation algorithm based on Ant- Colony(CAAC). CAAC not only can enables minimize the cognitive users´ handoff rate but also can reduce the handoff latency because of its simple operations and need none or seldom coordination with other cognitive users.
