Mobile ad hoc networks are becoming very popular in wireless communications due to the latest advances in technology. This has allowed millions of people to communicate with each other over wireless networks using mobile devices. Moreover, the latest models of many vehicles are equipped with communication devices which allow them to form a new type of ad hoc wireless networks, called Vehicular ...

Wireless mobile ad hoc networks (MANETS) are self configuring, dynamic networks in which nodes are free to move. In mobile ad hoc networks, the major performance constraint comes from path loss and channel fading. This project implements a channel adaptive routing protocol which extends the Ad hoc On-Demand multipath Distance vector (AOMDV) Routing protocol to accommodate channel fading. This c...

Ad hoc networks are special networks that do not require an infrastructure. Nodes of such networks are usually mobile and wireless. Wireless nodes use a shared medium for communication, so they are able to communicate with many nodes directly provided they are within communication range of those nodes. In this article we present a study of secure ad hoc routing protocols for wireless Networks. ...

Sending multiple copies of packet to different nodes is called Multicasting. Wired and infrastructure-based wireless networks are supported by many multicast routing protocols. But, applying this concept in Mobile Ad hoc wireless networks (MANETs) is a big challenge. Problems in ad hoc networks are the scarcity of bandwidth, short lifetime of the nodes due to power constraints and dynamic topol...

The focus of this paper is to survey the use of EXOR routing scheme and routing metrics to be applied in hybrid wireless networks over the traditional unicast routing protocols used for mobile ad hoc networks. On performing a thorough analysis of various literatures, it is proposed that use of EXOR with ETX metric in hybrid wireless networks would give a better throughput than that of the tradi...

Now a day, security in Mobile Ad hoc Network (MANET) is very important issue. Due to dynamic topology and mobility of nodes, Mobile Ad hoc Networks are more vulnerable to security attacks than conventional wired and wireless network. Nodes of Mobile Ad hoc Network communicate directly without any central base station. That means in ad hoc network, infrastructure is not required for establishing...

A Mobile ad-hoc network (Manet) is a system of wireless mobile nodes dynamically self-organizing in arbitrary and temporary network topologies. People and vehicles can thus be internetworked in areas without a pre-existing communication infrastructure, or when the use of such infrastructure requires wireless extension. Therefore, such networks are designed to operate in widely va ying environme...

In recent years the advancements in wireless communication technology and mobile computing fueled a steady increase in both number and types of applications for wireless networks. Wireless networks can roughly be classified into cellular networks which use dedicated infrastructure (like base stations) and ad hoc networks without infrastructure. A Mobile Ad Hoc Network (MANET) is a collection of...

In This paper presents a novel multicast routing protocol for mobile ad hoc wireless networks. The protocol, termed ODMRP (On-Demand Multicast Routing Protocol), is a mesh-based, rather than a conventional treebased, multicast scheme and uses a forwarding group concept (only a subset of nodes forwards the multicast packets via scoped flooding). It applies on-demand procedures to dynamically bui...

Wireless ad hoc networks are growing important because of their mobility, versatility, and ability to work with fewer infrastructures. The mobile ad hoc network is an autonomous system consisting of mobile nodes connected with wireless links. Establishing a path between two nodes is a complex task in wireless networks. It is still more complex in the wireless mobile ad hoc network because every...
