简介
This paper explores direct phone-to-phone communication (via WiFi interface) among vehicles to support mobile sensing applications. Direct communication among drivers' phones is important in improving data collection efficiency and sharing participatory sensing information in an inexpensive manner. We design a practical and optimized communication mechanism for direct phone-to-phone data transfer among drivers' phones that strategically enables phone-to-phone and/or phone-to-WiFiAP communications by optimally toggles the phone between the normal client and the hotspot modes. We take advantage of the WiFi hotspot functionality on smartphones, and hence require neither involvement of participants nor changes to existing wireless infrastructure and protocols. An analytical model is established to optimize toggling between client and hotspot modes for optimal system efficiency. We fully implement …
