Providing entity authentication and authenticated key exchange among nodes are both target objectives in securing ad hoc networks. In this chapter, a security framework for authentication and authenticated key exchange in ad hoc networks is introduced. The framework is applicable to general ad hoc networks and formalizes network phases, protocol stages, and design goals. To cope with the divers...

As wireless devices become more pervasive, mobile ad hoc networks are gaining importance, motivating the development of highly scalable ad hoc networking techniques. In this paper, we give an overview of the Safari architecture for highly scalable ad hoc network routing, and we present the design and evaluation of a specific realization of the Safari architecture, which we call Masai. We focus ...

Much progress has been made toward solving the problem of routing packets inside an ad hoc network, but there are presently no complete proposals for connecting ad hoc networks together to form larger networks, or for integrating them with wired internets. This paper describes a technique that allows a single ad hoc network to span across heterogeneous link layers. Using this technique, we can ...

A mobile ad hoc network can be defined as a network that is spontaneously deployed and is independent of any static network. The network consists of mobiles nodes with wireless interfaces and has arbitrary dynamic topology. The network suffers from frequent link formation and disruption due to the mobility of the nodes. A clustering method is used for obtaining a hierarchical organization for t...

Mobile Ad hoc Network is a collection of mobile nodes in which the wireless links are frequently broken down due to mobility and dynamic infrastructure. Routing is a significant issue and challenge in ad hoc networks. In Mobile ad hoc network, due to mobility of nodes network topology change frequently and thus, routing become challenging task to transfer the data from source to destination. A ...

A wireless mobile ad hoc network (MANET) is a collection of solely independent nodes that communicate with each other by forming a single hop/multi-hop network, and maintain connectivity in a decentralized manner. The important characteristic of the ad hoc network is that the nodes move randomly around the area of deployment making the topology highly dynamic. Because of this configuration and ...

Ad hoc network is infrastructure less network which posses characteristics like decentralized administration and very less efforts for setup. Due to this, it is most suitable for many applications like military, disaster area, rescue operation, collaborative computing and conference meeting where it is not possible to setup wired network or infrastructure based wireless network. During any disa...

Ab8tmct-A mobile ad-hoc network is composed of only mobile nodes, which are distributed dynamically, without any wired backbone or centralized entities. Each terminal in the mobile ad-hoc network also has the role of the router, but the frequent changes of the terminal positions induce the waste of time, energy and computing power for updating the routing table with the paging, and also may pro...
