Reducing the transmission cost is one of the most important issues in multi-hop ad-hoc networks. Considerable research has been done on efficient routing and data accessing algorithms. However, most previous research on routing schemes focus on topological structures, and not much attention has been made to data content distributions in ad-hoc networks. The exponential emergence of multimedia applications puts further challenges to the routing schemes. Due to the restrictions of ad-hoc networks and the volume of multimedia data, efficient data accessing schemes are needed for various applications.
