Mobile ad hoc network (MANET) has been generally regarded as an ideal network model for group communications. However, the security deployment for MANET routing operations is problematic. Firstly, existing secured routing protocols are deficient in achieving both authentication efficiency and full scale of security. In addition, the diversity of routing protocols presents difficulties in the ge...

A mobile ad hoc network is characterized by constraints such as limited bandwidth, energy constraints, less memory and processing capabilities. Also MANET’s are required to be deployed under scalable conditions for some applications. A routing protocol is a central to the design of such networks. In this paper we compare the energy conservation of proactive routing protocols like DSR and AODV. ...

IP anycast allows a source node to transmit IP packets to a single destination node, out of a group of destination nodes. It can be an important paradigm for an ad-hoc network in terms of resource, robustness and efficiency for replicated service applications. DSR is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. This...

In Wireless sensor network sensor nodes have a limited battery life and their efficient utilization is a very much importent task. Their are many ways are proposed for efficient utilization of energy.For efficient energy utilization many topologies,protocals are proposed by the help of which we can maximize the battery life. In this paper we propesed a methode in which a correlation is made bet...

MANETs are infrastructure less and can be set up anytime anywhere. One of the main design constraints in mobile Ad Hoc networks (MANETs) is that they are power constrained. Hence, every effort is to be channeled towards reducing power. More precisely, network lifetime is a key design metric in MANETs. In this kind of network the mobility rate of nodes is high, so excessive use of energy and als...

Multipath on-demand routing protocols for mobile ad hoc networks try to reduce control overhead and end-to-end delay by computing multiple paths with a single route discovery process. We propose Graph-based Multipath Routing (GMR), a novel multipath routing protocol that generate the network topology graph to compute all link disjoint paths in the network. The destination node computes link dis...
