Executive Summary

An important issue in the design of mobile computing is how to manage the location information of mobile nodes in wireless cellular networks. The existing system has two approaches. First approach is spatial quantization technique in which location update takes place only when the mobile terminal move from one location area to other and second approach is temporal quantization in which location update takes place only after a specific time threshold. In this paper, the authors introduce Intelligent Agent Quantization (IAQ) which is based on prediction of movements and distance between node and Base Station Controller (BSC) to locate the mobile nodes. The main idea of using IAQ is reduce the update cost considerably with slight increase in paging cost.
