Proxy mobile IPv6 protocol becomes one of the most popular mobility management protocols due to its seamless handover as well as relieving mobile nodes during the mobility process. Relieving mobile nodes during the mobility process also eases the deployment of mobility protocols. However, achieving mobility management via additional network entities results in issues such as long handoff latency, packet loss, signalling cost, load distribution as well as mobility support in basic proxy mobile IPv6. However, to address and solve these issues; researchers and experts have enhanced its performance in a number of directions to provide the best possible solution. Efforts are still in progress to exploit effective features to optimize the functionality of PMIPv6 protocol extensions.

In this research study, the existing PMIPv6 extensions are analysed for the main factors affecting its performance, in order …
