A Seamless Handover Based MIH-Assisted PMIPV6 in Heterogeneous Network(LTE-WIFI)


We consider the user equipment (UE) velocity as a vital trend in association problem in heterogeneous networks (HetNets), since there is a considerable relation between the velocity and the handover failure (HOF) as well as the probability of unnecessary handovers (ping-pong (PP) events). Several works have been carried out, in the context of standards and scientific research to perform the vertical handover process, such as the IEEE 802.21 Media Independent Handover(MIH) framework and Network Mobility Basic Support Protocol as a proxy mobile internet protocol version 6 (PMIPV6). Therefore, in our paper, we found that interconnecting those two frameworks will be effective in terms of handover decision-making. In addition, to solve the impact of velocity in handover process, we need to carefully and dynamically optimize handover parameters for each UE according to his velocity and coverage area of the access point (AP). To detect any variation in the velocity and evaluate if a transfer is necessary: MIH will study periodically the Allan Variance (AVAR) of received signal strength (RSS) from the serving AP and PMIPv6 will take over the control and execute the handover based on the results obtained by MIH. To evaluate our contribution, it was necessary to configure a heterogeneous network environment (LTE-WIFI) and to integrate MIH PMIPv6 for seamless handover. Simulation results show that it can not only gain relatively accurate velocity, but also reduces the number of PP and HOF.
