A WiFi-Direct Based Local Communication System

The infrastructure-based networks will be unavailable in the case of infrastructure failures (e.g., earthquake and tsunami) or in crowded areas (e.g., concert and conference hall). This promotes the evolution of location communication systems, which also benefit offloading computing, mobile edge computing and mobile crowdsourcing. In this paper, we utilize Wi-Fi Direct (WFD) to develop a local communication system. We not only present an intra-group communication solution by the native characteristics of WFD, but also propose a general solution for the bidirectional inter-group communication, which is beyond the scope of WFD specifications. Experimental results show that the maximum throughput of intra-group communication could reach up to 31.7 Mbps, and the maximum throughput of inter-group communication is 8.26 Mbps.
