Information Dissemination in Mobile Ad-Hoc Geosensor Networks

Abstract

Abstract. This paper addresses the issue of how to disseminate relevant information to mobile agents within a geosensor network. Conventional mobile and location-aware systems are founded on a centralized model of information systems, typified by the client-server model used for most location-based services. However, in this paper we argue that a decentralized approach offers several key advantages over a centralized model, including robustness and scalability. We present an environment for simulating information dissemination strategies in mobile ad-hoc geosensor networks. We propose several strategies for scalable, peer-to-peer information exchange, and evaluate their performance with regard to their ability to distribute relevant information to agents and minimize redundancy.

Decentralized Monitoring of Moving Objects in a Transportation Network Augmented with Checkpoints

“…This idea of using the movement of objects in this way has already received much attention in the literature, also termed the mobility diffusion effect [39], participatory data transfer [40] and is closely related to opportunistic data dissemination [41,42].…”

Estimating the Relevance of Information in Inter-Vehicle Ad Hoc Networks

“…• In [13], the authors focus on how to disseminate relevant geospatial information (mainly road hazards). They propose a dissemination strategy that they say to be similar to the opportunistic exchange proposed in Mobi-Dik.…”

Dissemination of information in inter-vehicle ad hoc networks

“…Thus, for example, the dissemination strategies proposed in [7] may be suited to specific events (mainly, road hazards), but the features of different types of events (e.g., mobile events) are not considered. The work presented in [9] focuses only on highway scenarios, does not take the relevance of data into account, and does not consider different types of events.…”

“…Other data dissemination protocols specific to V2V are being proposed (e.g., [7], [8], [9]). In [7], three dissemination protocols are studied: the flooding strategy (communicate all the known events to all the peers within communication range, which is a protocol with important disadvantages [8]), the epidemic strategy (only inform a certain number of peers), and 3) the proximity strategy (inform only the peers within a certain distance of the location of the event).…”

Within the TrafficView project, three dissemination protocols for highway scenarios are evaluated in [9]: 1) dissemination by vehicles circulating in the same direction (same-dir), 2) dissemination by vehicles moving in the opposite direction (opp-dir), and 3) dissemination by vehicles moving in both directions (bi-dir).…”
