LORD: A Locality-Based Distributed Data Sharing System for Highly Dense and Dynamic MANETs

The rapid development of mobile communication techniques enables mobile video-on-demand and video sharing applications, which allow the sharing of video data among mobile handset users and vehicles whenever and wherever. These applications have been penetrating into our daily life with dramatic speed. Traditional video sharing systems built on infrastructure wireless networks suffer from the problems of single point of failure, hot spots, and low-scalable transmission. Mobile Ad Hoc Network (MANET) consisting of mobile nodes is a promising alternative structure for flexible and distributed video data sharing without central control. This paper presents a locality-based video sharing system for highly dense and dynamic MANET, namely LORD. LORD provides a series of protocols about region-based video centric storage and retrieval, which can provide highly efficient, scalable and dynamism-resilient video sharing services with low overhead. Simulation results are provided to show the superiority of LORD.
