- W577287463 abstract "The major issue of the integration of wireless and wired ATM is thesupport of user mobility. In effect, many technical challenges have been posed dueto mobility support. One of the most important challenges is the rerouting of activeconnections of mobile user during handover. The rerouting of connections mustexhibit low handover latency, limit the handover delay or disruption time, maintainefficient routes and minimise the impact on existing infrastructure.To date, two dominant approaches have been proposed to support mobilityinto fixed ATM network. The first is the mobility enhanced switches approach andthe second is the separate network-elements specific to mobility approach. Thefirst approach implies updating the existing ATM switches with mobile specificfeatures. The mobility functions in the second approach are entrusted to a controlstation attached to the ATM switch as is implemented by the Magic WANDprojects. In this thesis, we investigate how mobility can be supported using bothapproaches. To demonstrate the effectiveness of the above approaches, wecompare the performance by analytically derived formulate for their hand overlatency, hand over delay, buffer size, and bandwidth requirements. The formulatewere derived for both backward and forward hand overs using a number ofpotential rerouting schemes proposed for wireless ATM network.The results show that the mobility enhanced switches approach has slightlybetter performance than the separate network elements approach. The results alsoshow that backward handover has better performance than forward handover interms of the handover delay and buffer requirement. Finally, the results show thatthe Anchor Switch rerouting scheme is the best among other rerouting schemesproposed for wireless ATM." @default.
