Võrguliikuvus

Võrguliikuvus, often translated as network mobility, refers to the ability of a mobile device or node to maintain its network connectivity and services as it moves across different network access points or even different networks. This movement can be physical, such as a user walking with a smartphone, or logical, such as a virtual machine migrating between servers. The primary goal of võrguliikuvus is to ensure seamless and uninterrupted communication for users and applications, regardless of their location or the underlying network infrastructure.

Key challenges in achieving effective võrguliikuvus include maintaining session continuity, managing IP address changes, ensuring security, and providing consistent quality of service. Technologies like Mobile IP (MIP) were developed to address these issues by allowing a mobile node to keep its original IP address while roaming. More advanced solutions involve various handover mechanisms, such as hard and soft handovers in cellular networks, and seamless mobility protocols in wireless local area networks.

The concept of võrguliikuvus is crucial for the widespread adoption and effective functioning of mobile computing, wireless networking, and the Internet of Things (IoT). It underpins the user experience in modern mobile applications, enabling features like real-time communication, location-based services, and cloud access without manual reconfiguration. As networks become more heterogeneous, with a mix of Wi-Fi, cellular, and other access technologies, the importance of robust võrguliikuvus solutions continues to grow.
