Location is a valuable information for services implemented in wireless networks. Location systems often use the infrastructure of already deployed cellular networks. Accordingly, location systems spend resources from the network they use. This paper proposes a middleware to reduce the consumption of network resources and optimize the location traffic 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 fulfills the required quality of service (QoS) and minimizes the resource operating expense. In addition, MILCO takes advantage from ongoing and carried location processes to reduce the overall expenditure of resources. Results show that MILCO can reduce the location-process failures and improve the figures of latency for the location provisioning and resource usage in cellular networks such as UMTS.
