Abstract: Wireless connectivity may not be available in congested locations (such as concerts or conference-halls) or may be interrupted by infrastructure outages caused by earthquakes and tsunamis. They are the great boon when it comes to device-to-device communication based on technologies like Wi-Fi-Direct and Bluetooth. However, no existing research builds a fully functional communication system which is local in nature, nor does it consider how the user mobility can be supported. A fuzzy logic-based normalised quantitative decision (FNQD) approach was proposed by the recent researchers, but it is suffering with the distance coverage among the communicating devices. We put forward an intragroup communication solution for local setup without the interference of any external network support. We propose a Bluetooth and Wi-Fi-Direct (Wifi_BL) system that improves the distance coverage obtained from the existing fuzzy logic-based normalised quantitative decisions. The proposed Wifi_BL system attains better distance coverage over the existing FNQD.

Keywords: local communication; Bluetooth; Wi-Fi-Direct; distance coverage; fuzzy logic.
