A common feature of all wireless mobile data networks is the dynamic nature of the propagation environment. Our work introduces a real-time propagation model that runs independently on each node in a mobile wireless ad hoc network. It computes and predicts RF propagation conditions for wireless links between mobile nodes and assists the network routing protocol in making hand-offs or choosing t...

Recently, long-range wireless networks such as cellular networks, and short-range wireless communication devices such as IrDA, Wireless LAN(IEEE802.11), and Bluetooth become popular. In this paper, we introduce the concept of ad-hoc communication which is the short-range wireless communication between the information devices that happen to meet each other. We clarify the characteristics of ad-h...

A mobile ad hoc network is a collection of autonomous nodes that communicate with each other by forming a multi-top wireless network. Different from conventional wireless networks, the resource of the nodes in ad hoc networks is limited and there may be tens of thousands of low-power energy constrained nodes in ad hoc networks. As such, the costs of the nodes resource and the network size shoul...

Over the past decade wireless multi-hop ad-hoc networks have received a tremendous amount of research focus. Mobile devices equipped with wireless short range communication technologies make possible new applications for spontaneous communication, interaction and collaboration. The collaboration is used to facilitate communication when mobile devices are not able to establish direct communicati...

A mobile ad hoc network is a collection of digital data terminals equipped with wireless transceivers that can communicate with one another without using any fixed networking infrastructure. Communication is maintained by the transmission of data packets over a common wireless channel. The absence of any fixed infrastructure, such as an array of base stations, make ad hoc networks radically dif...

In mobile ad hoc networks (MANETs) the wireless links are error prone in nature and the mobile devices are highly mobile, therefore traditional Internet QoS protocols like RSVP cannot be easily migrated to the wireless environment. The management of bandwidth is critical to establish session guarantees for traffic flows. This paper examines the challenges of incorporating scalable bandwidth man...

A Mobile Ad-Hoc Network (MANET) is a decentralized network of autonomous mobile nodes able to communicate with each other over wireless links. We selected three routing protocols DSDV, DSR and AODV for measuring QoS parameters. We have used the network simulator ns-2 for simulating routing protocols using group mobility model, and present the results of simulations of networks of 40 wireless mo...

A mobile ad hoc network is a network in which a group of mobile computing devices communicate among themselves using wireless radios, without the aid of a fixed networking infrastructure. This paper presents a logical survey on to detect the misbehaving node in Mobile Ad hoc Network (MANET) using Intrusion Detection System (IDS). Mobile ad hoc networks have a different characteristic from wired...

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...
