ABSTRACT: Internet of Things (IoT) is ubiquitous, including objects or devices
communicating through heterogenous wireless networks. One of the major
challenges in mobile IoT is an efficient vertical handover decision (VHD)
technique between heterogenous networks for seamless connectivity with
constrained resources. The conventional VHD approach is mainly based on
received signal strength (RSS). The approach is inefficient for vertical
handover, since it always selects the target
network with the strongest signal without taking into consideration of
factors such as quality of service (QoS), cost, delay, etc. In this paper, we present a hybrid approach by
integrating the multi-cri- teria based VHD (MCVHD) technique and an algorithm
based on fuzzy logic for efficient VHD among Wi-Fi, Radio and Satellite
networks. The MCVHD provides a lightweight solution that aims
to achieving seamless connectivity for
mobile IoT Edge Gateway over a set of heterogeneous networks. The proposed solution is evaluated in real time using a testbed containing real IoT
devices. Further, the testbed is integrated with lightweight and efficient software techniques, e.g., microservices, containers,
broker, and Edge/Cloud techniques. The experimental results show
that the proposed approach is suitable for
an IoT environment and it outperforms the conventional RSS Quality based VHD by minimizing handover failures,
unnecessary handovers, handover time and cost of service.
