A MIH-based approach for best network selection in heterogeneous wireless networks

The fifth-generation communications system (5G) will commercialize at 2020 in order to satisfy the increasing demands on data rate and also to enable the internet of things (IoT). One of the most challenging issues in 5G communications network is to provide provisioning quality of service (QoS) while maintaining seamless mobility for user equipment (UE). This paper proposes a QoS-aware handover algorithm based on fuzzy-TOPSIS to trigger and achieve the optimal cell selection. The proposed algorithm integrates both advantages of fuzzy logic and technique for order preference by similarity to an ideal solution (TOPSIS). The weights value of network attributes is first calculated by Entropy and the fuzzy-TOPSIS algorithm are then applied to rank each access networks. This QoS-aware algorithm is able to achieve the optimal Mean Option Score (MOS) for UE by considering QoS related parameters such as network jitter and packet loss ratio. The simulation results indicate that the proposed algorithm can guarantee good QoS while maintaining number of handover at a low level.

“…The PMIPv6 is responsible for executing handover based on information about velocity and received signal strength indicator (RSSI) gathered by the MIH entities. Several other relevant approaches have been proposed in the literature to solve mobility management issues such as in our previous works [15][16][17].…”

Mobility management has always been a challenging and important issue for the next-generation all-IP mobile networks. Seamless mobility is one of the requirements to provide real-time services in such networks. Proxy Mobile IPv6 (PMIPv6) has been developed by the Internet Engineering Task Force (IETF) as a network-based mobility management protocol to support the mobility of IP devices. Although several designs have been presented in the literature to reduce the amount of PMIPv6 signalling and latency handover, they do not satisfy the real-time application requirements. In this study, the authors first propose a novel vertical handover algorithm that helps to anticipate the handover process in an efficient manner. The suggested approach is based on PMIPv6 and IEEE 802.21 Media Independent Handover (MIH) standard. The authors also added a new MIH primitive in order to indicate that a handover is needed to be done very soon. The triggering of such process is done thanks to two proposed dynamic thresholds. According to the analytical evaluation and simulation results, the proposed method guarantees a significant reduction of the handover delay and the signalling overhead, handover blocking probability and packet loss.

“…This policy is motivated by the abundance of resources in lower tiers, lower power consumption due to closer distance, and lower service cost. The handoff decision in heterogeneous networks is still an open research problem [10,17,32,36]. However, using another handoff policy would change the ZRT mobility model parameter and the presented framework remains applicable.…”

Heterogeneous networking is envisioned as a key solution for accommodating the traffic surge resulting from resource demanding applications such as video streaming. In this paper, the diversity in cost, coverage, and resource availability in heterogeneous systems is exploited to minimize the streaming session cost in three-tier integrated systems. A sub-optimal streaming decision engine is developed to overcome the complexity of the original problem whose solution contradicts with both the limited processing capabilities of end-user equipment and short handoff delay requirements. Our results show that the developed framework achieves significant monetary cost savings in comparison to typical greedy streaming behavior. Additionally, our solution can be easily tuned to compromise the tradeoff between monetary, signaling and quality cost components.
