Vertical Handover Decision Algorithm Using Ants’ Colonies for 4G Heterogeneous Wireless Networks

Abstract: With the development of 4G mobile telecommunication systems, providing users with the convenience of a seamless continuous connection is not enough anymore. Users want to be connected through the best available network with the best quality of service. It is necessary to have a good decision-making algorithm which decides whether it is necessary to perform handoff to another network, the best network to vertically perform handoff to, and the right time to initiate the handover. This paper proposes a new approa… Show more

“…where the authors indicate possible underutilization of network resources, lack of fairness, and inappropriate load balancing in the network. The RSS metric is conventionally used for selection and handover (Benaatou et al, 2017;El Fachtali et al, 2016), but some authors (Mahardhika et al, 2015;Miyim et al, 2013) argue that it is only convenient to start the handover and then adding some other QoS criteria is needed for better results. Therefore, to maximize the utilization in the C-RAN network, a decision for RRH-Sector selection should consider the requirements and constraints of the user and the operator.…”

“…Several mobility management algorithms have been proposed in [13][14][15][16][17] to predict the target cell. The authors of [13] suggest an effective measurement scheme and network investigation for user equipment mobility from macrocell to femtocell (hand-in/handover scenario).…”

“…Furthermore, to decrease the number of needless handovers and the number of handover failures, the authors in [16] proposed ant colony optimization for the handover stage. The proposed scheme uses several input factors along with RSS, such as prediction of traveling distance, UE velocity, cost of service, and bandwidth.…”
