“…Location is also useful to operators further than the revenue they may obtain from providing it. This is because location information can be used to optimize the management of network resources [21,22,23], by taking advantage of, for example, intelligent paging and intelligent resource allocation for handoff [24,25] [in the case of the latter, the network knows the location, speed and direction of the mobile station (MS) and can therefore reserve a channel for handoff in the next cell].…”

Location is valuable information for services implemented in wireless networks. Location systems often use theinfrastructure of cellular networks that have already beendeployed. Accordingly, location systems spend resources of the network they use. This paper proposes a middleware to reduce the consumption of network resources and optimize the location traffic that is being carried. This middleware, called MILCO (Middleware for Location Cost Optimization), selects the optimum location technique depending on the request, i.e. the location technique that satisfies the quality of service (QoS) required and minimizes the resource operating expense. In addition, MILCO takes advantage of ongoing and carried location processes to reduce the overall expenditure of resources. Our results show that MILCO can reduce location-process failures and improve latency figures for location provisioning and resource use in cellular networks such as UMTS.

“…Even though some work has been done in this direction [7], [8], many of the underlying issues associated with location-based handovers such as location accuracy, availability of location information across different wireless networks, and the signalling overhead introduced during a handover as a result of location updates, have not yet been properly addressed.…”

Even though numerous proposals have been made for mobility management schemes in heterogeneous wireless IP networks, no single solution has emerged that is capable of supporting seamless and low latency handovers required to satisfy the stringent delay requirements of real-time multimedia applications. In this paper, we present a location-based mobility management architecture for realtime applications in a heterogeneous network environment. Handover latency is minimised by integrating optimised application layer mobility management signalling using the Session Initiation Protocol (SIP) with location-based information of nearby access points (APs). A newly defined Access Point Location Protocol (APLP) is used to disseminate geospatial information and network parameters associated with various APs to location-aware mobile devices that use this information to construct a virtual map of the APs. An intelligent decision engine (DE)implemented in the mobile node (MN) combines the information provided by APLP with knowledge of the user's mobility pattern and policy preferences to anticipate handovers.
