Connecting points to the nearest point belonging to a set of lines is an interesting problem that arises in many practical problems, especially Infrastructure Design Problems. In this paper an algorithm is presented for this problem. This algorithm is based on enumeration. To test the performance we define and explain several heuristic approaches. The algorithms is then, in comparison to the other...
Geometric models are a proven aid for calculating the CapEx needed for a network deployment and used widely by telecommunication network operators for their access networks. However, for the economic viability an accurate estimation of the delivered bandwidth is important as well. In this paper a method is described to calculate a bandwidth profile for an area under investigation, given a single topology...
Mobile operators' investments depend largely on the costs of the radio network. The efficiency of building and maintaining the radio network is determined largely by the quality of the radio planning process. The planning tool, the propagation predictions and the spatial traffic input together are the key ingredients of the planning process. In this paper we describe a method to create high quality...
The need for higher bandwidth by customers urges the network providers to upgrade their networks. Fibre to the home or Fibre to the curb are two of the scenarios that are considered. To make a proper assessment on the economic viability, a good estimation of the roll-out costs of the networks are important. Geometric models are easy to use for this estimation, but can be inaccurate. In this paper...
Rolling out a Fibre to the Home (FttH) architecture is very expensive, mainly due to all the trenching that is labour extensive. In this paper we present a method for planning the last mile in FttH in a cost effective way and extend this method for incorporating and minimizing the inconvenience and social costs this work brings. To do this, we model the problem of connecting the houses with FttH in...
Over the past few decades the demand for bandwidth for Internet access has been growing at an unprecedented rate, and this growth is not likely to slow down in the near future. Rolling out Fibre to the Cabinet/Curb networks quickly will be the only way for telecom operators to meet the growing customer demand. This requires a fibre connection to the cabinets or even closer to the homes. This raises...
A first step in congestion management is making sure that the average production and consumption per time unit over time match as well as possible, we call this tactical congestion management. The main question in this paper is: what is an optimal mix of DGs such that electricity loss is minimized.
