چکیده
The objective of this project is to improve the connectivity of Ad Hoc Cognitive Radio network using the temporal traffic dynamics with Scheduling and Queuing. In this first set the primary and secondary users. These users are requesting for data. Queuing will be done based on the service requirement. Scheduling will be done based on calculating the distance and according to the data type. Apply the temporal traffic and establish the connection. The connection between the two users is based on the transmission range. So find the traffic of two users and find the distance. After finding the distance, identify the type of data. Finally establish the connection between the primary and secondary users. In addition this project proposes the queuing in CR set-up.

متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
