In this article, the authors study querying binary large objects (blobs) such as video and voice clips in a network of vehicles communicating wirelessly. They introduce a novel paradigm, describe a set of derived query-processing strategies and compare them along three dimensions: push versus pull, whether or not a communication infrastructure is utilized, and whether metadata dissemination is separated...
In this paper we provide an architecture for Tactical Information Middleware for bandwidth constrained information management. We propose the ideas of rank-based data dissemination, and the use of a tactical information management query language. These ideas will deal with dynamic changes in bandwidth and explore opportunistic data dissemination. Thus, will lead to a cross layer design of a system...
In this paper, C3G-A (Combining the third generation mobile communication network and Ad hoc network) system is presented. Call Admission Control (CAC) plays an important role in radio resource management of wireless communication networks. It permits or denies the call arrival connection requests based on the certain criteria. To analyze the performance of CAC in C3G-A system, Markov chain model...
We examine the problem of mobile local search via P2P databases. We argue that P2P databases can lead to a new form of mass communication that may revolutionize local search. We introduce our approach, MOBI-DIK, which is a platform-independent search engine based on mobile P2P databases.
In this environment each mobile peer has a local database that stores and manages a collection of reports (where each report is a product record, or a coupon), and all the local databases maintained by the mobile peers form a mobile e-commerce (or, more generally, a mobile P2P) database. Queries on this database are posed by potential customers, and they search for coupons and products pertaining...
Peer-to-peer data dissemination in a mobile ad-hoc environment is characterized by three resource constraints, including energy, communication bandwidth, and storage. Most of the existing studies deal with these constraints separately. In this paper we propose an algorithm called RANk-based dissemination (RANDI), which provides an integral treatment to the three constraints. The contribution is in...
