Abstract

Mobility management for heterogeneous networks (HetNets) remains one of the most important topics of modern research due to the joining of numerous user equipment (UE) with different capabilities. Handover is one of the core issues in network management that allows UEs to navigate, but it remains a challenging issue for continuous development in the field of telecom networking. One of the most important proposals in the field of networking is the Software Defined Network (SDN). This study exploited the SDN by shifting most of the handover procedure cost to SD-Switch and the SD-Controller. Next, we introduced other parameters along with signal strength (signal-to-interference plus noise ratio, delay, bandwidth, UE trajectory, UE speed) to ensure that the appropriate target Point of Access (PoA) is selected for the UE. UEs measure the parameters of neighboring PoAs with their serving PoA, as well as their location coordinates, and then send them to the SD-Switch via their serving PoA. A polynomial function is used in SD-Switch to track the UE’s trajectory, and when a handover process is requested from the UE, SD-Switch will choose the appropriate PoA and only send the handover command to the UE for transportation. The performance metrics show an improvement in the proposed method in reducing the number of handovers, packets delay ratio, reducing packets loss ratio, and reducing the average of signaling messages overhead for the entire system. The proposed method reduced the average-signaling message overhead by more than 75% compared to previous studies.
