INTERNET OF THINGS (IoT) MOBILITY SUPPORT BASED ON DISTRIBUTED SENSOR PROXY MIPV6

摘要

It is expected that the footprint of the Internet of Things (IoT) will increase in the future. In order for this increase to occur, a network architecture which is flexible and capable of handling multiple flows with varying requirements as well as dynamically meeting the current demands. A new era of dynamic entities (nodes) within an environment like smart hospitals and cities is being empowered by IoT. The Sensor Proxy Mobile IPv6 (SPMIPv6) has been specifically determined for IP-based wireless sensor network (WSN) mobility with the aim of potentially reducing the consumption of energy by means of preserving the mobile nodes from being part of the handoff process. The majority of the shortcomings of the Proxy Mobile IPv6 (PMIPv6) such as non-optimized communication path, long handoff latency, and bottleneck issues were inherited by SPMIPV6. An improved SPMIPv6 architecture called Distributed SPMIPv6 (DSPMIPv6) is presented in this work with the aim of addressing the aforementioned problems. The solution proffered in the present architecture includes de-coupling the entities that are part of the control and data planes; the Dynamic Mobility Access Gateway (MAG) located close to the edge of the network distributes and manages the data plane, while the control plane, is dependent on a central entity called Sensor Local Mobility Anchor (SLMA). The introduced design is evaluated analytically, and the numerical results show that the performance of the DSPMIPv6 design is better than that of both SPMIPv6 and PMIPv6 protocols in terms of Local Mobility Anchor (LMA) load, and transmission cost performance metrics.
