Paging and Location Management in IEEE 802.16j Multihop Relay Network

摘要

IEEE 802.16j is an emerging wireless broadbandnetworking standard that integrates infrastructure base stationswith multihop relay technology. Based on the idle mode operationin IEEE 802.16j, we propose a novel location management andpaging scheme. It integrates the paging area-based and thetimer-based location update mechanism. In paging area-basedscheme, an idle mode mobile station updates when it moves toa new paging area. In timer-based scheme, an idle mode MSupdates when the location update timer expires. In this work, weformulate the mathematical model to evaluate the performance ofthe proposed paging scheme. A new random walk mobility modelthat is suitable for modeling in multihop relay network is created. Optimization of location update timer is also investigated.
