-The proliferation of Internet of Things (IoT) devices has ushered in a paradigm shift in the way we interact with our surroundings. As these devices seamlessly exchange data across heterogeneous networks, maintaining uninterrupted connectivity and optimal quality of service (QoS) becomes a paramount concern. The process of vertical handoff, which facilitates the seamless transfer of communication sessions between different networks, is of particular significance in this dynamic IoT landscape. This research paper delves into the realm of "Context-Aware Vertical Handoff Algorithms for IoT-enabled Environments," aiming to harness the power of context-awareness to enhance the efficacy of vertical handoff decisions in IoT scenarios. The introduction highlights the intricate network challenges posed by IoT's diverse devices and applications. These challenges necessitate the development of innovative solutions that can adapt to varying communication technologies, device constraints, and QoS demands. The focal point of this exploration lies in the integration of context-awareness into vertical handoff algorithms. Context-awareness leverages real-time contextual information, encompassing factors such as device location, network conditions, application requirements, and user preferences, to make informed handoff decisions that align with the unique demands of each IoT situation. Drawing from the wellspring of context- aware computing, the paper delves into the mechanics of context-aware vertical handoff algorithms. It explores their attributes and capabilities, shedding light on how these algorithms leverage context to optimize handoff decisions.

As the IoT landscape brings forth its own set of challenges, the paper addresses considerations like limited resources, heterogeneous data, and intermittent connectivity. It delves into the spectrum of algorithm types and approaches that align with the IoT's intricacies, ensuring that vertical handoff decisions resonate with the unique characteristics of IoT devices. In the quest to gauge the effectiveness of context-aware vertical handoff algorithms in IoT scenarios, the paper outlines a comprehensive methodology for performance evaluation. This methodology involves defining IoT-centric performance metrics, such as data delivery reliability, energy efficiency, latency, and adaptive decision-making, which accurately capture the impact of context-awareness on QoS enhancement and device efficiency. Through practical case studies, the paper demonstrates how context-aware vertical handoff algorithms find application across various IoT domains, from smart cities to healthcare. It unveils how these algorithms address the dynamic challenges presented by real- world scenarios, where devices navigate between heterogeneous networks and diverse application requirements.
