Mobile Ad-Hoc Networks (MANETs) are becoming increasingly popular as more and more mobile devices find their way to the public, besides ―traditional‖ uses such as military battlefields and disaster situations. They are being used step by step in every-day stages. With this increased usage of MANETs comes the need for making the networks secure as well as efficient, something that is not readily...
Mobile entities with wireless links are able to form a mobile ad-hoc network. Such an infrastructureless network does not have to be administrated. However, self-organizing principles have to be applied to deal with upcoming problems, e.g. information dissemination. These kinds of problems are not easy to tackle, requiring complex algorithms. Moreover, the usefulness of pure ad-hoc networks is ...
Mobile Ad Hoc Network (MANET) is a kind of wireless ad hoc network. It is a self-managed network of mobile routers connected by wireless links with no access point. Every mobile device or node in a network is independently controlled in autonomous mode. The mobile devices are free to move randomly and organize themselves arbitrarily. The wireless ad-hoc network is particularly vulnerable due to...
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...
Ad Hoc networks does not connected central mode. It is infrastructure less wireless network. Due to high mobility of nodes and multipath propogations topology of this network is dynamically changes. It is self configured network. No. of mobile nodes are connected internally in this network. Mobile Ad Hoc networks protocols are different from other internet protocols of infrastructure based wire...
The idea of extending Mobile IP capabilities to ad-hoc networks introduces fast agent discovery, increases cell coverage of access points, and extends ad-hoc network size by providing connection to the Internet. We aim to show that an adaptive protocol is required since different protocols are optimum for different environments. We propose two protocols called MEWLANA-TD and MEWLANA-RD based on...
Advances in wireless personal area networking p. 3 A comparative study of routing strategies for wireless sensor networks : are MANET protocols good fit? p. 5 Detecting disruptive routers in wireless sensor networks p. 19 Energy-efficient data dissemination in sensor networks using distributed dynamic tree management p. 32 Virtual coordinates with backtracking for void traversal in geographic r...
Topology control in mobile ad-hoc networks allows better spatial reuse of the wireless channel and control over network resources. Topology control algorithms tend to optimise network power usage by keeping the topology connected. In this paper, we provide an overview of a range of centralised and distributed topology control algorithms proposed in literature. We also provide a comparison of th...
Many security schemes for mobile ad-hoc network(MANET) have been proposed so far but none of them has been successful in combating the different types of attacks that a mobile ad-hoc network often faces. This paper is providing one way of mitigating attacks in mobile ad-hoc networks by authenticating the node who tries to access this network .This scheme has been applied by using cellular autom...
