Mobile Adhoc Network is a kind of wireless ad hoc network where nodes are connected wirelessly and the network is self configuring. MANET may work in a standalone manner or may be a part of another network. In this paper we have compared Random Walk Mobility Model and Random Waypoint Mobility Model over two reactive routing protocols Dynamic Source Routing (DSR) and Adhoc On-Demand Distance Vec...

The main aim of the MultiText experiments for TREC-7 was to derive very short queries that would yield high precision and recall, using a hybrid of manual and automatic processes. Identical queries were formulated for adhoc and VLC runs. A query set derived automatically from the topic title words, with an average of 2.84 terms per query, achieved a reasonable but unexceptional average precisio...

Reliable secure multicast communication in mobile adhoc networks is challenging due to its inherent characteristics of infrastructure-less architecture with lack of central authority, high packet loss rates and limited resources such as bandwidth, time and power. Many emerging commercial and military applications require secure multicast communication in adhoc environments. Hence key management...

In a Mobile adhoc network (MANET), Mobile nodes communicate with each other using multihop wireless links. There is no stationery infrastructure, for instance there is no base station. Each node in the network also acts as a router, forwarding data packets for other nodes [2] an adhoc network can be formed by mobile computers with wireless interfaces that communicate among themselves without an...

A wireless Mobile Adhoc NETwork (MANET) is an infrastructure-less mobile network which is based on radio to radio multi-hoping and has no centralized controller or a fixed router. All nodes are capable of movement and can be connected dynamically in an arbitrary manner. Due to the dynamic nature of network topology, frequent mobility, bandwidth limitation, limited battery power, routing in MANE...

Mobile adhoc network (MANET) is a collection of mobile devices which form a communication network with no pre-existing wiring or infrastructure. Multiple routing protocols have been developed for MANETs. As MANETs gain popularity, their need to support real time applications is growing as well. Quality of service(QoS) provisioning is becoming a critical issue in designing mobile adhoc networks ...

Knowledge of end-to-end path capacity is useful for video/audio stream adaptation, network management and overlay design. Capacity estimation in wired and last-hop wireless networks has been extensively investigated, but a thorough and systematic study in ad hoc, multihop wireless networks is still lacking. Yet the rate of a wireless link can change dynamically (and rapidly) due to changes in i...
