碩士 === 國立中山大學 === 資訊工程學系研究所 === 96 === With the state-of-the-art IC technology, we can share a variety of digital content stored in our mobile devices via wireless communications. When requests for digital content arrive, base stations have to search for at least one copy of the digital content. We extend the concurrent search approach to efficiently location digital content. In addition, we propose the opportunistic concurrent search scheme in which a base station could use a single channel to page a number of mobile stations simultaneously. We use computer simulations to evaluate the performance and justify the usage of the proposed schemes.
