An enhanced leader election for Cognitive Radio Ad-Hoc Networks

Leader election protocol is a classical approach for coordination and synchronization between nodes in a network. Cognitive Radio Network is the improved version of wireless network in which the primary concern is spectrum sharing or spectrum utilization among the secondary user (SU) nodes. Henceforth, for this type of network, there is also requirement of leader election approach for the synchronization and coordination among secondary users, since they access the unused or less-used free spectrum of primary users. This paper presents an enhanced method for the election of leader in Cognitive Radio Ad-Hoc Networks [4], which can be implemented or adopted with some change to a leader election protocol for this network. Since for Cognitive Radio Networks a very less in number leader election algorithm is proposed by different authors and simultaneously all the critical parameter of Cognitive Radio Networks is not considered. In this paper we have considered primary user (PU) involvement during leader election phase in Cognitive Radio Ad-Hoc Networks.
