Systems optimization for mobility management
Ashutosh Dutta · ProQuest Demo Repository · 2010
Mobile networking technology seeks to preserve the user experience as the user moves and thereby crosses from one network into another. A mobility event is the result of one network con-nection path being replaced by another via the rebinding of common system properties that may happen at any one of several protocol layers of the mobile node. The rebinding is a sequential pro-cess and each process takes a nite amount of time. This overall process generates a period of time in which network service is degraded by transient data loss and increased end-to-end delay. Applica-tion specic and protocol specic ad hoc solutions are available for mitigating the service disruption. However, formal techniques to characterize this problem and to develop optimization methodologies for these processes have not been studied as part of a systematic framework for mobility solutions. This dissertation develops a systematic and formalized systems model that analyzes the basic opera-tions associated with a mobility event and characterizes several systems optimization techniques for these processes. The proposed formal mobility systems model represents these basic operations in the form of a discrete event dynamic system. I analyze this general mobility systems framework and develop
