Base Station Placement Based on Force Fields

Abstract

Network planning and optimization becomes more and more important in cellular mobile communications due to the growing complexity of the networks. Besides taking new key performance indicators into account such as energy efficiency, the augmented heterogeneity, caused by a variety of radio access technologies (e.g., 3G and beyond as well as WiFi) and network node types (e.g., micro and femto cells), leads to an exploding dimension of the planning process. On the other hand, the degrees of freedom increase as well, giving rise for new optimization techniques.In this paper a novel approach for optimizing cellular deployments is presented. The model is based on characterizing the interrelations (among base stations and between base stations and the environment) by force fields, motivated by the physics of multiple particles in a closed system. Further, an algorithm is proposed which tracks the trajectory of base station locations under the presence of forces, focusing on finding a balanced state with minimal net force. Also, it is elaborated on how to combine different force types in order to capture different quality aspects of a network.

Dynamic Clustering and on/off Strategies for Wireless Small Cell Networks

“…1) User association: Classical UE association mechanisms are often based on the maximum received signal strength (RSS) or signal to interference and noise ratio (SINR) [28]. However, these criteria are oblivious to the time load (and thus, the expected number of flows and delays) which may lead to overloading BSs yielding lower spectral efficiencies.…”

Force field based joint optimization of strictly monotonic KPIs in wireless networks

“…We analyse this approach and give a detailed discussion in the following sections. The idea to employ forces for a joint optimization is inspired by [4], where a force field approach is used for optimal base station (BS) placement.…”

Deployment of 5G networking infrastructure with machine type communication considerations

“…Thus, backhaul links and SBSs should be considered jointly during network planning [2] to guarantee the system performance. Conventional works on base station (BS) deployment have focused mainly on scenarios in which fiber connection backhaul links are available for all candidate locations [5][6][7][8][9]. In other words, only sites with existing fiber connections are regarded as potential sites.…”

“…Although interesting deployment problems have been studied, existing works [5][6][7][8][9]11] have only focused on fibre backhaul links and HTC. Such works can not be extended to solve the deployment problem of the next-generation networks since the impact of MTC and the designing of backhaul network have been neglected.…”
