-The purpose of this research is to study and analyze various congestion control mechanisms using a number of routing protocols in Mobile Adhoc Network (MANET). As MANET is infrastructureless network so node movement and data load traffic which exceeds the network capacity, can not be predicted which leads to problem of congestion. The objective of this paper is to design a comparative analysis...

This paper describes the setup and results of our contributions to the INEX 2006 AdHoc and Feedback tasks.

We present in this paper a new mechanism for the OLSR routing Protocol, aiming to improve mobility and energy management in mobile adhoc network. As known OLSR use the concept of an MPR mechanism where only nodes selected as MPRs can relay broadcast packet received from their selectors, those nodes have to satisfy certain requirements to assure this mission , speaking of stability and physical ...

The increasing diffusion of wireless devices suggests novel service deployment scenarios where there are no constraints on device mobility and distributed applications are the result of impromptu collaborations among wireless peers. Mobile adhoc network (MANET) makes it possible to dynamic changes in topology and in the availability of resources from different sources. Different sources can be ...

The Mobile adhoc network (MANET), is a collection of mobile wireless nodes that self-organize without the aid of centralized control or any preexisting infrastructure. This paper presents the effect of MAC protocols (MAC 802.11, MAC/TDMA) on various routing protocols in order to choose the best routing protocol and MAC protocol to enhance the performance. The simulation compared three adhoc rou...

We present results of a study in which 50 searchers, of varying degrees of experience in information retrieval (IR), each performed searches on two TREC4 adhoc interactive track topics, using a simple interface to the INQUERY retrieval engine. The foci of our study were: the relationships between the users' models and experience of IR, and their performance in the TREC-4 adhoc task while using ...
