A Mobile Ad hoc NETwork (MANET) is a kind of wireless ad-hoc network, and is a self configuring network of mobile routers (and associated hosts) connected by wireless links – the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the network's wireless topology may change rapidly and unpredictably. Such a network may opera...

This project is an extension of the Ad-hoc Walkie-Talkie project by UIUC PhD Lewis Tseng and my colleague UIUC undergraduate Pratch Piyawongwisa. Ad-hoc Walkie-Talkie is an application simulating walkie-talkie on top of an ad-hoc wireless network. A wireless sensor network comprises a number of sensor nodes, each of which has limited energy supply as well as intrinsic sensing and communicating ...

Achieving secure communication is especially challenging in wireless ad hoc networks, where no infrastructure or central authority exists, and the state and topology of the network is dynamic and fault-prone. These unique characteristics of wireless ad hoc networks make traditional cryptographic mechanisms and assumptions inappropriate. In this paper, we propose mobile agents as a solution to t...

The emergence of portable computing devices such as laptops, palmtops and personal digital assistants (PDAs) has fuelled the demand for mobile connectivity and hence, led to the development of wireless local area networks (LANs). Wireless LANs offer users increased mobility and flexibility compared with traditional wired networks, and may be classified as either infrastructure wireless or ad ho...

An ad hoc network is a dynamically reconfigurable wireless network with no fixed infrastructure or central administration. Each host is mobile and must act as a router. Routing and multicasting protocols in ad hoc networks are faced with the challenge of delivering data to destinations through multihop routes in the presence of node movements and topology changes. This paper presents the On-Dem...

Most previous work on real-time event-based communication has assumed infrastructure-based networks. The underlying assumption of this work is that application components are stationary and that a fixed network infrastructure exists to facilitate communication between them [1]. Ad hoc wireless networks comprise sets of mobile nodes connected by wireless links that form arbitrary wireless networ...

On wireless computer networks, ad-hoc mode is a method for wireless devices to directly communicate with each other. Operating in ad-hoc mode allows all wireless devices within range of each other to discover and communicate in peer-to-peer fashion without involving central access points (including those built in to broadband wireless routers). An ad-hoc network tends to feature a small group o...

Broadcasting is a fundamental operation in any wireless networks, more so in wireless ad hoc sensor networks, where each sensor node has limited transmission range and battery power. Although broad-casting in wireless ad hoc sensor networks has many advantages but it can cause serious problems like—broadcast storm, which could cause a lot of contention, redundant, retransmission, collision and ...

Wireless Mobile ad-hoc network (MANET) is an emerging technology and has great strength to be applied in critical situations like battlefields and commercial applications such as building, traffic surveillance. MANET is infrastructure less, with no any centralized controller exist and also each node contain routing capability, Each device in a MANET is independently free to move in any directio...

A wireless ad-hoc network is a decentralized type of wireless network [7]. InVANET, or Intelligent Vehicular Ad-Hoc Networking, defines an intelligent way of using Vehicular Networking [7]. InVANET combines different ad-hoc networking technologies for easy, accurate, effective and simple communication between vehicles on dynamic environment. Vehicular Ad-hoc Networks are expected to implement a...
