This paper presents a positioning algorithm to improve the performance of location systems based on two-way TOA techniques. This algorithm, which we call passive-TDOA, consists of computing the time-difference-of-arrival (TDOA) measurements from the TOA messages that some terminals generate in the positioning process. Passive-TDOA offers accurate results under optimum geometry. This work goes a step...
Location systems based on already-deployed cellular networks spend the resources of the underlying communications network. This paper proposes a middleware that reduces the consumption of resources and optimizes the location traffic load. This middleware, called MILCO (Middleware for Location Cost Optimization), is assumed to run on networks that can choose from among several location techniques (e...
This paper proposes a middleware to reduce the consumption of network resources and optimize the provision of location of traffic. This middleware, called MILCO (middleware for location cost optimization), selects the optimum location technique for each location request, i.e. the location technique that satisfies the required quality of service (QoS) and which, at the same time, minimizes the operating...
