A dynamic IP paging algorithm based on the velocity of mobile node for proxy mobile IPv6

초록

Significant IP mobility mechanisms have been designed to minimize the handover overhead of mobile nodes. Although many efficient algorithms such as Mobile IP, HMIP and PMIP have been proposed, they did not attempt to upgrade their paging mechanisms that also heavily affect the power consumption of mobile nodes. Considering a good paging scheme is important because more than 95% of mobile nodes are moving in the idle state and change their states to active only for paging area updates. However, existing paging schemes assume the configuration of fixed paging areas and do not explore the dynamic nature of a paging area size depending on the states of mobile nodes. In this paper, we propose a novel dynamic IP paging scheme, where a paging area size is configured dynamically based on the speed and direction of a mobile node. The performance evaluation results demonstrate that the proposed IP paging scheme reduces the power consumption, compared to a fixed IP paging scheme.
