Trustworthy P2P Data Delivery for Moving Objects in Wireless Ad-Hoc Networks

Abstract

In a mobile Peer-to-Peer (P2P) environment, where inherent resource constraints (e.g. battery, bandwidth and computing power) exist, the notion of reliability and efficiency especially around communication of messages between peers is a crucial factor. In this paper, we introduce a trustworthy token-passing multi-point relays (TOP) data dissemination scheme for moving objects in wireless ad-hoc networks. The proposed scheme encompasses the trustworthy model and location-based scheduling technique capable of determining the most optimal schedule for the target peers to receive messages based on the location and mobility parameter. The performance of the proposed approach is compared against the existing state of techniques namely pure flooding and Trustworthiness-based Broadcast (TBB) scheme. The experimental evaluation includes a number of metrics, such as transmission cost, computational cost and message deliverability, of which the results showed promising performance of the proposed scheme.
