A mobile ad hoc network (MANET) is formed by a group of mobile wireless nodes, each of which functions as a router and agrees to forward packets for others. Many routing protocols (e.g., AODV, DSDV, etc) have been proposed for MANETs. However, most assume that nodes are trustworthy and cooperative. Thus, they are vulnerable to a variety of attacks. We propose a secure routing protocol based on ...

Ad hoc networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology; thus the need for a robust dynamic routing protocol that can accommodate such an environment. To improve the packet delivery ratio of Destination-Sequenced Distance Vector (DSDV) routing protocol in mobile ad hoc networks with high mobility, a message exchange scheme for its inv...

In this paper, an extended version DSDV (eDSDV) Protocol is proposed for Ad Hoc networks. eDSDV overcomes the problem of stale routes, and thereby improves the performance of regular DSDV. The proposed protocol has been implemented in the NCTUns Simulator and performance comparison has been made with regular DSDV. The performance metrics considered are packet-delivery ratio, end-end delay, drop...

Efficient routing protocols can provide significant benefits to mobile ad hoc networks in terms of both performance and reliability. Mobile Ad-hoc Network (MANET) is an infrastructure less and decentralized network which needs a very strong dyNAMic routing protocol. There are many routing protocols available for such networks and many have been proposed so far. Amongst the most popular ones are...

IEEE 802.11 is a standard for mobile ad hoc networks (MANET), implemented with various different protocols. Destination-Sequenced Distance-Vector Routing (DSDV) is one of the several protocols of IEEE 802.11 intended to provide various Quality of Service (QOS) parameters under acceptable range. To avoid the collision and interference the MAC protocol has only two solutions, one, to sense the ph...

MANET (Mobile Ad hoc Network) is a self organizing and self configuring network without the need of any centralized base station. It is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. MANETs are infrastructure less and can be set up anytime, anywhere. In MANETs, the nodes are mobile and battery operated. As the nodes have limited battery re...

We present ARM (Adapting to Route-demand and Mobility), a control mechanism that allows any proactive routing protocol to dynamically adapt in a totally distributed manner to changes in node mobility and workload route-demands. Each node independently maintains a mobility metric indicating how fast its neighborhood is currently changing, and a route-demand metric indicating which destinations a...
