Due to this, multipath routing protocols become an important research issue. In this paper, we suggest and im-plement a consistent node disjoint multipath routing protocol. The key purpose of the proposed scheme is to determine all available reliable node-disjoint routes from source to destination with minimum routing control overhead. In the route discovery method, the routes with good link quality and route expiration time are selected as the primary and backup routes. If there is any route failure during the data transmission through primary path, the next obtainable backup route with good link quality and route running out time is selected from the list. The performance of the proposed protocol will be evaluated using NS-2 and will be revealed that it re-duces the packet drop and delay there by escalating the packet delivery ratio.
Virtual Networks Through Manets , a Study on Qos Enabled NDMR

To sustain multimedia applications such as video and voice MANETs need a proficient routing protocol and quality of service (QoS) mechanism. Node-Disjoint Multipath Routing Protocol (NDMR) is a practical protocol in MANETs: it reduces routing overhead radically and achieves multiple node-disjoint routing paths. QoS support in MANETs is a significant issue as best-effort routing is not able for supporting multimedia applications. This paper presents a novel version of NDMR; QoS enabled NDMR, which brings out agent-based SLA management. This augmentation allows for the intelligent selection of node-disjoint routes depending on network circumstances, thus fulfilling the QoS requirements of Service Level Agreements (SLAs).

Group key establishment involves creating and distributing a common secret for all group members. However, key management for a large and dynamic group is a difficult problem because of scalability and security. Dynamical changes in network’s topology causes feeble conviction relationship among the nodes in the network. In MANETs a mobile node operates as end terminal as well as an midway router. Therefore, a multi-hop situation occurs for communication in MANETs; where in between source and destination there may be one or more malicious nodes. In this paper, we proposed a key management scheme. We assume that MANETs is alienated into groups having a group leader in each group. Group leader has accountability of key management in its group. Proposed key management scheme is a decentralized method that does not need any Trusted Third Party (TTP...

Nodes of wireless networks communicate by sending signals transmits a message through a single source to single destination. Signals are in the encoded form when receives at the node it processes decoded/ encodes with information received from previous nodes. In the wireless network, there is a problem of routing path complex and combinatorial problem transmission from source to destination. In this system, we investigate the optimal routing problem in signal transmission from source to destination for the multi-hop network. We use the technique of rate less code which is used to accumulate the data with each packet in the transmission. This can decrease the total energy; reduce delays in transmission for transmitting data from the source to the destination. Proposed system enables significant performance through the shortest path routing using Flo...
