Abstract:

With the rapid advancement of smart devices and mobile computing technologies, content sharing in dynamic wireless networks is in substantial demand. To address this problem, in our former work, we presented the Delay/Disruption-tolerant Mobile Content Sharing Network (DMCSN). In this paper, we further examine the routing strategy under the DMCSN framework. We first design the composite interest for organizing user interests. Then, an interest routing strategy based on incremental name relevance (IRINR) and a content routing strategy based on incremental contact opportunity (CRICO) are devised to correspond to the two stages of the content acquisition process:the spreading of the interests and the returning of the contents. Our simulation results validate the following:first, the composite interest can reduce redundant dissemination of content; second, matching of interests and contents are accomplished in a more cost-effective manner under the guidance of IRINR compared with baseline methods; and finally, the integration of IRINR and CRICO achieves a good balance between cost and performance.
