Optimal sizing of a network for smart metering

Abstract:

In this article we propose an optimal sizing of WSN network, the network required for the location of Universal Data aggregation UDAP. These allow data exchange between the UDAP and the smart meter. We consider a georeferenced stage for randomly placed points on the map, getting potential candidates sites to be activated by a UDAP. There are several problems when we consider the coverage, capacity and interference. But we have parameters that we can control and some we can not control parameters, then to solve the problems presented. We assume some parameters as a constant radius depending on the technology used, as we assume a scenario without interference. When we take into account the capacity we consider to each UDAP has limited capacity so that He can serve multiple users simultaneously, then this is an important parameter for dimensioning. In addition to the network may have scalability in the future, we try to minimize the number of channels used. Interference is a very important aspect to consider, that parameter appears when you have two UDAP functioning at a very short distance from each other. For all inconvenienced, we propose an algorithm that optimizes the number of UDAP used, using a MILP to cover at least a percentage N of users, but considering all the problems described.
