Abstract

In this paper, we propose a hybrid wireless data access algorithm in mobile hotspots, which enables ubiquitous Internet access in vehicular networks. We first introduce a novel architecture with proxy cache (PC) for strongly consistent wireless data access and investigate the trade-off relationship between a PC-based poll-each-read (P-PER) algorithm and a PC-based callback (P-CB) algorithm. We then present a hybrid wireless data access algorithm which reduces the transmission cost by adaptively choosing P-PER and P-CB depending on the access-to-update ratio. Extensive simulation results are given to demonstrate the performance of the proposed algorithm.
