Seamless service handoff based on Delaunay triangulation for Mobile Cloud Computing

It is being envisaged that a wide variety of applications can be running on Mobile Cloud Computing (MCC) in the near future. The MCC suggests that the speed and direction of Mobile Terminal (MT) are unpredictable. That easily leads to large service latencies when MT handoff, and even results in the failure of time-critical applications for a long time. To address this issue, we propose a service handoff mechanism using the Delaunay triangulation (DTSHM). The DTSHM, which splits the network into Triangle topology by Delaunay triangulation, and accurately obtains MTs target access point. The master-standby service model is a key service platform for the DTSHM, which is composed of a master service point and two standby service points. Since the standby service points can in advance authenticate and cache the MT needed data packet, the MT can obtains lower service delay when do handoff. The simulation results and performance analysis show that the DTSHM works well.
