Abstract

Mobile wireless communication is growing in scope and importance all around the world. The IP network is fast becoming the global network of choice for multimedia communications. Mobile IP network is also fast making its way to the consumer market. However, efficient and scalable mobility management is a key enabler in the mobile IP networks. Secondly, mobile terminals are portable devices that often depend on battery power; they therefore require efficient power management in order to prolong battery life. Paging is an important mobility management function that, not only helps to reduce location update cost, but also helps to conserve mobile terminal battery power. Therefore, efficient paging design is necessary for reliable IP mobility management. Several paging algorithms have been proposed in the literature. These proposals, while generally achieving the overall aim of terminal power conservation, differ in the balance between the amount of delay incurred to locate a given mobile node and the bandwidth cost incurred. This paper provides a paging design for cellular mobile Internet based on the architecture of CHIMA (a Completely Hierarchical IPv6-based micro mobility Management Architecture). The paging algorithm took advantage of the locality in user behavior to achieve a fast and sequential mobile node tracking, which considerably reduced bandwidth and delay costs.

Key words: Mobile communications, mobile IP, paging, resource management.
