Internet of Things (IoT) is ubiquitous, which includes objects communicating through heterogenous networks. One of the challenges in mobile IoT is vertical handover decision (VHD) between heterogenous networks for seamless connectivity. Conventional VHD approach is based on received signal strength (RSS), which is limited to only RSS Quality and hence inefficient to decide best network for vertical handover. This thesis proposes multi-criteria based VHD (MCVHD) algorithm for efficient VHD between Wi-Fi, Radio and Satellite network. The experiment results show that MCVHD outperforms the conventional RSS Quality based VHD by minimizing handover failures, unnecessary handovers, handover time and cost of service by selecting best available network using multi-criteria parameters. The proposed IoT solution also employs container based microservices architecture. The results show that the container technology produces negligible resource overhead and can be used on resource constrained IoT devices like Raspberry Pi 3, for efficiently managing IoT application and services.
