In this paper we examine the benefit of reports about resources in mobile ad-hoc networks. Each disseminated report represents information about a spatio-temporal event, such as the availability of a parking slot or a cab request. Reports are disseminated by a peer-to-peer broadcast paradigm

Abstract The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. DSR allows the network to be completely self-organizing and self-configuring, without the need for any existing network

Automatic discovery of services and resources is a crucial feature to achieve the expected user-friendliness in Mobile Ad-hoc Networks (MANETs). Due to limited computing power, scarce bandwidth, high mobility and the lack of a central coordinating entity, service discovery in these networks is a

answers to be useful. Using a simplified mobility model, we analytically quantify the benefits from cooperation (in terms of the system’s ability to satisfy spatio-temporal constraints), which we show to go beyond simple space-time tradeoffs. In managing the limited storage resources of such cooperative

Abstract — In this paper we study the feasibility of disseminating reports about resources via vehicular ad-hoc networks. Each disseminated report represents information about a spatial-temporal event, such as the availability of a parking slot at a particular time. The simple flooding algorithm

Abstract. The extension of grid computing technology to ad-hoc mobile environments is giving rise to the development of ad-hoc grids, which enable wireless and mobile users to share computing resources, services, and information. However, the adaptation of grid technology to ad-hoc networks

Abstract — Space-time communications can help combat fading and hence can significantly increase the capacity of ad hoc networks. Cooperative diversity or virtual antenna arrays facilitate spatio-temporal communications without actually requiring the deployment of physical antenna arrays. Virtual

... component for ad hoc communications and collaboration in ubiquitous computing environments. In this paper, a lightweight service advertisement and discovery protocol for MANET (Mobile Ad hoc NETworks) based on ODMRP (On-Demand Multicast Routing Protocol) is presented. Its service advertisement

Abstract –With the rising popularity of network-based applications and the potential use of mobile ad hoc networks in civilian life, an efficient resource discovery service is needed in such networks for quickly locating resource providers. In addition, to improve user experience, QoS awareness
