Fast Response and Energy Efficient Caching Policy for Information Centric Networking with Flexible User Mobility

摘要

In this research we propose a moderate caching policy, in which the most popular or requested data will be stored in lower level access point routers of network. Data will be sorted as name-wise that reduces the searching time. Due to reduction of searching time, the power consumption is substantially reduces and the user will get fast response. Moreover, our new architectural design will improve the mobility to user. If users change the position after requesting data, the users may loss the lower level access point routers connectivity. But In new star network topology the user can get the data from other side's lower level access point routers. That increases the possibility of get popular data in the other lower level access point routers in the same network. This may help users to get desired data in shorter time. There for the mobility will be increased. We also design the network for YouTube. Most naturally, when client requests for data, then it comes from the server. But we assume that if user can get the data from intermediate node then link utilization will be reduced and power will be saved, response time will be shorter and node data will be performed as backup.
