Mobility refers to the ability of the user or other mobile entity to communicate and access services, irrespective of any changes in the location or in the technical access environment. The chapter begins by explaining mobility and mobility management including protocol reference model (data, control and management plane) and network reference model. The last part of the chapter discusses moving objects and aspects related to moving object database (MOD) like modeling, location tracking, indexing, uncertainty management and querying. This chapter’s appendix describes aspects related to spatio-temporal databases: This chapter’s appendix introduces fundamental concepts in temporal data model and temporal database. Last part of appendix introduces spatio-temporal data model and spatio-temporal database system. Spatio-temporal database can deal with the objects’ temporal and spatial properties uniformly, and it can manage data that is evolving with time.
