WSN12-2: Hierarchical Pipeline Paging in Hierarchical Wireless Networks
Yang Xiao, Mohsen Guizani, Hui Chen · Globecom · 2006
In this paper, we propose and study a hierarchical pipeline paging (HPP) for multi-tier hierarchical cellular networks, in which each mobile terminal (MT) can be paged in any tier of a network. Furthermore, paging requests are queued in N different waiting queues, where N stands for the number of tiers, and multiple paging requests in each waiting queue are served in a pipeline manner. We study the HPP scheme analytically in terms of discovery rate, total delay, paging delay, cost, and load balance, validated with simulations.
