“…), a set of users demanding for a given amount of traffic and a set of candidate APs with a fixed available bandwidth are defined. When an AP can not provide enough capacity to the users it covers, a traffic constraint is violated ( [1], [2]). [1] proposed an integer linear program handling traffic as a constraint on each access point capacity but also as a global planning objective that minimizes the maximum of channel utilization of the access points covering the area.…”

“…3) QoS Criterion: In this paper, a QoS-based criterion implementing a per-user throughput constraint is proposed. Previous works introducing such a constraint considered a unique data rate for all nodes and a perfect bandwidth sharing between nodes, keeping constant the total bandwidth [1], [2], [3]. In a 802.11b network however several users share the bandwidth at 4 different data rates 1, 2, 5.5 or 11M bits/s and even more with 802.11g networks.…”

“…The former concerns the formulation of such a QoS criterion in a wLAN planning problem and the later the evaluation of such a criterion. In ( [1], [2], [3]), it is assumed that the available aggregate bandwidth of an access point is fixed, albeit stochastic performance evaluation of 802.11 shown different results. Indeed in ([4], [5]), the available bandwidth of an AP was shown decreasing with an increasing number of connected users, because of two main reasons.…”

International audienceThis paper proposes an automatic base station planning approach. This approach does not only try to assess usual objectives such as radio coverage, but further implements a quality of service (QoS) constraint. This criterion is here defined as the mean available bandwidth per user. Its computation takes the medium access control (MAC) layer behavior, the multiple bit rates of IEEE 802.11b and the coverage area of each access point (AP) into account. A Markov chain is used to evaluate the available bandwidth of each cell independently. This is sensible because a non-overlapping criterion between cells is used during the planning phase to avoid interference between adjacent cells. The planning process estimates an optimal number of APs and their placement minimizing an aggregate criterion using a Tabu meta-heuristic. The AP's coverage is estimated with a powerful multi-resolution radio propagation simulator previously described. This paper presents results for a QoS oriented planning process providing a predefined minimum peruser throughput. The example provided herein applies for 100 users distributed over a 12600 m 2 building floo

“…Similar methods were also applied for indoor network environments, such as IEEE 802.11, in [4]- [7], where the access point (AP) positioning problem was tackled for homogeneous traffic. In [5], a hybrid heuristic Pareto approach was proposed, while in [6] the problem was solved by through a pure heuristic approach under different interference modeling assumptions.…”

In this paper, a new network planning framework is proposed for orthogonal frequency-division multiple access (OFDMA) cellular systems based on co-channel interference and traffic congestion avoidance. The network planning is formulated as a non-linear multi-objective optimization problem subject to minimum interference and related resource constraints at each cell under heterogeneous traffic. The multi-objective problem is represented by the throughput maximization of each single cell without penalizing the remaining cells, which results in a throughput equilibrium over the whole network. The fundamental objective is to maximize the throughput balance and, hence, traffic and cochannel interference congestions are avoided across the network. In order to maximize the equilibrium, the optimization problem is decomposed into a positioning problem and a resource allocation problem, which are solved by parallel heuristics and convex optimization. Additionally, a novel rotated polarization assignment method is proposed to minimize further the effect of the co-channel interference.
