Mobile Ad Hoc Networking Does Not Own Any Fixed Infrastructure And Hence, Stable Routing Is The Major Problem. The Mobility Nature Of Manet’s Node Facilitates Rediscovery Of A New Path To Organizing A Routing. In Order To Intensify The Quality Of Service And Routing Stability In Manet, We Propose A Dynamic Quality Of Service Stability Based Multicast Routing Protocol By Modifying The Cuckoo Sea...

Mobile ad hoc networks are infrastructure-less networks consisting of wireless, possibly mobile nodes that are organized in peer-to-peer and autonomous fashion. The highly dynamic topology, limited bandwidth availability and energy constraints make the routing problem a challenging one. The Swarm Intelligence paradigm has recently been used in solving the routing problem in static computer netw...

Definition: Wireless networks with intermittent connectivity (also called Delay or Disruption Tolerant Networks), are characterized by sporadic availability of end-to-end paths between end hosts. Existing TCP/IP packet routing protocols cannot cope with the lack of reliable end-to-end connectivity. New routing mechanisms are necessary. The Internet has been exceedingly successful in establishin...

nodes communicate with each other using multihop wireless links. There is no stationary infrastructure; for instance, there are no base stations. Each node in the network also acts as a router, forwarding data packets for other nodes. A central challenge in the design of ad hoc networks is the development of dynamic routing protocols that can efficiently find routes between two communicating no...

Cognitive radio is an enabling technology of dynamic spectrum access (DSA) networking. In DSA, unlicensed secondary users can coexist with primary licensed users and can share the radio spectrum opportunistically. Broadcasting is an important networking primitive that is useful for many CRN applications such as control information dissemination, warning notification, etc. Unfortunately, the spo...

An architecture to deploy virtual IP networks with P2P-like dynamic topology management is described. Existing virtual IP network deployment mechanisms do not allow for dynamic topology adaptation and fault-tolerance since provisioning of IP tunnels is performed only once when a virtual network is deployed. We propose a P2P-XBone, in which a P2P protocol such as DHT drives the topology and the ...

Network Reconfiguration Processes Olav Lysne, Timothy Mark Pinkston and José Duato Abstract Dynamic network reconfiguration is defined as the process of changing from one routing function to another while the network remains up and running. The main challenge is in avoiding deadlock anomalies while keeping restrictions on packet injection and forwarding minimal. Current approaches either requir...
