A Multipath Routing Protocol for Cognitive Radio Ad Hoc Networks
Multihop routing is the advanced technology in wireless Networks. Multipath routing protocols for MANET are deemed superior over conventional single-path routing as the former to reduce end to end delay, increase consistency and provide toughness. Quality of Service (QoS) is an essential feature of networks. One of the main problems in Ad-hoc networking is the delivery of data packets to the no...
متن کاملOn-demand routing protocols for cognitive radio ad hoc networks
Cognitive radio ad hoc networks (CRAHNs) are a class of cognitive radio networks. In recent years, they have gained popularity, and routing protocols have been proposed. Above all, the protocols based on on-demand routing are considered favorable in the literature. It is mainly because the accomplishments of ad hoc on-demand distance vector (AODV) routing and dynamic source routing (DSR) in mob...
متن کاملReceiver-Based Ad Hoc On Demand Multipath Routing Protocol for Mobile Ad Hoc Networks
Decreasing the route rediscovery time process in reactive routing protocols is challenging in mobile ad hoc networks. Links between nodes are continuously established and broken because of the characteristics of the network. Finding multiple routes to increase the reliability is also important but requires a fast update, especially in high traffic load and high mobility where paths can be broke...
متن کاملEnergy Aware Multipath Routing Protocol for Cognitive Radio Ad Hoc Networks
Cognitive radio networks (CRNs) have emerged as a paradigm addressing the problem of limited spectrum availability and the spectrum underutilization in wireless networks by opportunistically exploiting portions of the unused spectrum by licensed primary users (PUs). Routing in CRNs is a challenging problem due to the PU activities and mobility that are beyond the control of CRNs. On the other h...
متن کاملAn Energy-Efficient and Robust Multipath Routing Protocol for Cognitive Radio Ad Hoc Networks
Routing in cognitive radio ad hoc networks (CRAHNs) is a daunting task owing to dynamic topology, intermittent connectivity, spectrum heterogeneity, and energy constraints. Other prominent aspects such as channel stability, path reliability, and route discovery frequency should also be exploited. Several routing protocols have been proposed for CRAHNs in the literature. By stressing on one of t...
