On Detecting Termination in Cognitive Radio Networks

The cognitive radio network is an emerging wireless communication and computing paradigm where the network is not equipped with control infrastructure. The cognitive radios are allowed to execute the processes over the multiple heterogeneous channels without perturbing the licensed users of respective channels. The termination detection is a fundamental and non-trivial problem in the distributed computing systems. In this article, we present a termination detection protocol for heterogeneous multihop cognitive radio network. The proposed protocol applies the credit distribution and recovery approach. We present the two types of termination detection, i.e., strong and weak termination. Also, we give the correctness proof of the protocol.
