Ad hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. We compare the performance of three routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-Demand Distance Vector Routing (AODV), location-aided routing (LAR1).Our evaluation is based on energy consumption ...

Mobile ad hoc networks are formed by co operative association of wireless nodes communicating with each other without the use of infrastructure. Every node acts as a router in the network and enables the communication between nodes that are separated over their radio range. Typically in ad hoc networks one or more nodes may act as gateway connecting to the external world. The node acting as the...

Nowadays, the world gets more and more mobile in such a way that communication services are desirable anytime and anywhere. In this context, Mobile wireless ad-hoc networks, including mobile ad-hoc networks (MANETs) and Mesh-Networks, are systems of nodes that interconnect in a dynamical self-organized way providing an attraction especially during mission-crucial or time-crucial applications, f...

In multi hop wireless systems, such as wireless sensor networks, mobile ad hoc network, security is an important factor. It becomes more critical issue when we transmit important data between nodes. There are a lot of attacks available in wireless sensor network or mobile ad hoc network. In our paper we are going to discuss about a particularly devastating attack, known as the wormhole attack. ...

Today, Vehicular Ad Hoc Network (VANET) is an emerging technology. The routing problems in heterogeneous network become popular research area in the field of VANET for supporting different aspects of Intelligent Transportation System (ITS) applications. With the progress of wireless radio technology, telecommunication, various wireless specifications and protocols form the heterogeneous network...

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...

Wireless ad hoc networks can be flexibly and quickly deployed for many applications such as automated battlefield, search and rescue, and disaster relief. Unlike wired networks or cellular networks, no physical backbone infrastructure is installed in wireless ad hoc networks. A communication session is achieved either through a single-hop radio transmission if the communication parties are clos...

An ad-hoc network is a collection of wireless mobile nodes that forms a temporary network without any centralized administration. While early research effort assumed a friendly and cooperative environment and focused on problems such as wireless channel access and multihop routing, security has become a primary concern in order to provide protected communication between nodes in a potentially h...

An ad hoc wireless network is a collection of two or more devices or nodes or terminals with wireless communications and networking capability that communicate with each other without the aid of any centralized administrator also the wireless nodes that can dynamically form a network to exchange information without using any existing fixed network infrastructure. And it’s an autonomous system i...

Ad-hoc wireless networks are networks of cooperating users, with no reliance upon fixed infrastructure. Such networks are growing in popularity, as wireless communication hardware, both fixed and mobile, becomes more common and affordable. Much attention has been devoted to developing ad-hoc network systems, and many different strategies have been developed, for a variety of network scenarios. ...
