摘要:Use of mobility models to model user movement in mobile networks is a key aspect when developing and evaluating networking protocols in simulators. A trace obtained from an actual user movement is considered as being more realistic than using synthetic mobility models in simulators. Though realistic, usually, these traces lack information about the actual wireless contact durations between users. Most simulators use Unit Disk Graph (UDG) model to determine contact durations. However, due to the nature of radio propagations, a simplistic connectivity model (with UDG) may result in simulating unrealistic connectivity patterns. In this work, we have used an Android Smartphone application to collect GPS traces of moving users and their corresponding Bluetooth Low Energy (BLE) contact times to compare the viability of using UDG to determine contact durations. The results show that trace based model with UDG based wireless connectivity is an effective method to determine contact durations. © Springer International Publishing AG 2017.
