Spectrum Handoff Aware AODV Routing Protocol for Cognitive Radio Vehicular Ad Hoc Networks

Algorithm 1

//Spectrum handoff packet buffering at intermediate CR nodes//

	Spectrum handoff based CR-AODV {
	while (Avg_Queue_lengthold-CR-node < RED_minthresold) {
	Prioritybit = 0; //packet with no priority.
	REDpriority = Fa1se; //No need to create Priority buffer.
	Markerpriority = 0; //packets with no priority
	REDInput ()//InputRED buffer at new-CR-node. {
	REDInput = PacketsNon−priority + NormalIP;
	CongestionNotification = 0;
	Commonchannelold node−new node = True;
	}
