Information-Centric Local Resource Sharing System on Smart Phones

Device-to-Device (D2D) communication is considered as an efficient approach to improve current wireless networks. However, for inter-group communication, since devices are using the same IP address segment, IP conflicts can be induced into D2D networks. To address this problem, we propose an Information-Centric resource sharing system for D2D communication network. In the system, both P2P and WLAN network adaptor interfaces are adopted simultaneously for establishing a D2D network. A socket reusing mechanism is proposed for inter-group communication. In addition, to improve content distribution and retrieval, we base our system on Information-Centric networking (ICN) paradigm. We design ICN flow tables on network nodes to realize request forwarding and data backtracking. To demonstrate the feasibility and effectiveness, we have implemented the system on commercial Android devices using Wi-Fi Direct technology. Experimental results show that the proposed Information-Centric resource sharing system is feasible for D2D network in terms of data transmission and energy consumption. The average latency for transmitting 1MB data is 257.23ms; l.e., the throughput is up to 31.1 Mbps. The average energy consumption for transmitting 100MB data is only about 0.66 mAh.
