The problem of cache sharing for supporting data access in mobile ad hoc networks is studied in this paper. The key to this problem is to discover a requested data item in an efficient manner. In the paper, we propose two caching protocols, IXP and DPIP, which distinguish themselves from the existing ones in that they fully exploit in-zone broadcasts to facilitate cache sharing operation. In particular, the DPIP protocol offers an implicit index push property, which is highly useful for enhancing cache hit ratio in the neighborhood of a data re ....etc

ABSTRACT:
Secure communication, an important aspect of any networking environment, is an especially signicant challenge in ad hoc networks. The MANET paradism seeks to enable communication across networks whose topology and membership can change frequently. Its distinctive feature is that network nodes need to collaborate with their peers in supporting the network functionality. In such an environment, malicious or selfish nodes can disrupt or even deny the communications of potentially any node within the ad hoc net ....etc

Multipath Distance Vector Zone Routing Protocol for Asymmetric Mobile Ad-Hoc Networks
Abstract—
Most of the ad hoc routing protocols assume that all wireless networks aresymmetric (bidirectional links). In reality any practical network has some links may beunidirectional and hence the network is asymmetrical rather than symmetrical. The presenceof such links can reduce the performance of the existing protocol and could lead to networkclogging. In this paper we introduce a Multipath Distance Vector Zone R ....etc

A Multicast Protocol based on Zone Routing



Introduction to MZR:

What is MZR?
It’s a source initiated on-demand multicast routing protocol
Builds a multicast delivery tree rooted at the source based on the zone routing protocol
Does not depend on any underlying unicast protocol for global routing substructure
Why Multicast?
Ad hoc network  collaborative computing

Proactive versus Reactive

Proactive Routing Protocols
Exchange routing information periodically to maintain ....etc

Abstract
Mobile Ad Hoc Networks (MANET) are self-organizing multi-hop wireless networks. The MANETs are rapidly deplorable due to the absence of a fixed infrastruc- ture. A number of routing protocols have been proposed in solving routing problems for this type of network to provide and maintain better connectivity in the network. Before being implemented in real life the performance of a routing protocol is eval- uated primarily through the simulation experiments. This paper presents Taguchiâ„¢s method to optimize networks parameters ....etc
