A Protocol for Content-Based Communication in Disconnected Mobile Ad Hoc Networks

Abstract

Abstract. In content-based communication, information flows towards interested hosts rather than towards specifically set destinations. This new style of communication perfectly fits the needs of applications dedicated to information sharing, news distribution, service advertisement and discovery, etc. In this paper we address the problem of supporting content-based communication in partially or intermittently connected mobile ad hoc networks (MANETs). The protocol we designed leverages on the concepts of opportunistic networking and delay-tolerant networking in order to account for the absence of end-to-end connectivity in disconnected MANETs. The paper provides an overview of the protocol, as well as simulation results that show how this protocol can perform in realistic conditions.

Disruption-tolerant content-driven information dissemination in partially connected military tactical radio networks

“…These results were obtained either in real conditions, or using a simulator. For example, [8] presents some the results we obtained while simulating the behavior of 120 Wi-Fi enabled mobile terminals running DoDWAN, these terminals being carried by pedestrians such as students moving in a campus-like environment.…”

JOMS: A Java Message Service Provider for Disconnected MANETs

“…It has also been used in a military tactical network involving VHF battlefield radios with built-in modems, and proved robust and reliable in such harsh conditions [9]. The scalability and stability of the algorithms DoDWAN relies on have been verified in simulations, using scenarios involving hundreds of mobile hosts [5].…”

“…JOMS relies on a communication middleware system called DoDWAN (Document Dissemination in mobile Wireless Ad hoc Networks). This system was designed in our laboratory in order to support content-based information dissemination in D-MANETs [5].…”

“…In contrast JOMS presents a two-layer architecture: the upper layer is concerned with queue and topic management and utilisation, while the lower layer supports opportunistic communication. For the lower layer JOMS currently relies on DoDWAN, a middleware system we designed to support content-based information dissemination in D-MANETs [5]. Yet JOMS could theoretically be implemented above any other communication system, provided this system can operate satisfactorily in D-MANETs.…”

Broadband Access for All: Strategies and Tactis of Wireless Traffic Sharing

“…The ad-hoc networks are mobile, dynamic wireless networks that require no fixed infrastructures [4]. As the continuous end-to-end connectivity between its mobile nodes is not guaranteed, [5] pointed out that the ability to self-form and self-mange remains a major challenge.…”
