Erratum to “A Rendezvous Scheme for Self-Organizing Cognitive Radio Sensor Networks”
Junhyung Kim, Gisu Park, Kijun Han · International Journal of Distributed Sensor Networks · 2014
In the paper entitled “A rendezvous scheme for self-organizing cognitive radio sensor networks,” the corresponding author’s information was not correct and it is corrected here. We proposed an asynchronous channel hopping mechanism, called a hopping sequence guaranteeing rendezvous within a single period (HS-GRSP); cognitive radio (CR) nodes can rendezvous in a single period and reliably exchange control messages with each other. Equation (1) gives the length of guard sequence and its subsequences. However, it does not guarantee the appearance of a center channel in every subsequence in all cases. To make our scheme more robust, we changed (1) as follows:
