Location management is very important in location-based services to provide services to the mobile users like banking, city guides and many more. Ubiquitous and mobile devices are the source of data in location management and its significant operations are update and search method. Some studies to improve these were presented by using optimal sequential paging, location area scheme and hierarch...

This paper presents binary differential evolution based optimal reporting cell planning (RCP) for location management in wireless cellular networks. The significance of mobile location management (MLM) in wireless communication has evolved drastically due to tremendous rise in the number of mobile users with the constraint of limited bandwidth. The total location management cost involves signal...

Location management deals with how to track mobile users within the cellular network. It consists of two basic operations: location update and paging. The total cost of location management is the sum of the location update cost and the paging cost. There are many location management schemes, Location Areas and Reporting Centers are two classical and popular location management schemes. To the b...

Change point detection in sequences of functional data is examined where the functional observations are dependent. Of particular interest is the case where the change point is an epidemic change (a change occurs and then the observations return to baseline at a later time). The theoretical properties for various tests for at most one change and epidemic changes are derived with a special focus...

In networks where nodes are aware of their locations via the use of a GPS receiver or other localization techniques, geographic routing has been suggested to be the candidate of choice for robust and resource efficient routing. However, efficient location management algorithms are required for the source node to obtain the destination node’s location before it can start data transfer using geog...

This paper is presenting a comparative study of existing location management scheme with its various variants in Personal Communication Services (PCS) network. The existing location management scheme is based on two tier database architecture; Home Location Register (HLR) and Visitor Location Register (VLR).In the existing location management scheme, there is a single HLR. In the HLR, profile o...

Miniaturization of computing devices, and advances in wireless communication and sensor technology are some of the forces that are propagating computing from the stationary desktop to the mobile outdoors. Some important classes of new applications that will be enabled by this revolutionary development include location-based services, tourist services, mobile electronic commerce, and digital bat...

Location Management of mobile users in a cellular network is considered from a performance and privacy point of view. Location management covers tracking functionality and paging (searching) functionality. After a risk analysis of location management w.r.t. privacy, we focus on the paging strategy. A sequential search strategy is proposed which reduces the signaling on the air interface and als...
