“…SINR The SINR between any two nodes i and j in resource r is given by: (2) where P ij is the power received in j, I ij (r) is the interference power on the link and N 0 the noise power density. We have P ij = P i a ij for a xed nominal transmission power P i and a pathloss attenuation factor a ij .…”

The paper is devoted to modeling wireless mesh networks (WMN) through mixed-integer programming (MIP) formulations that allow to precisely characterize the link data rate capacity and transmission scheduling using the notion of time slots. Such MIP models are formulated for several cases of the modulation and coding schemes (MCS) assignment. We present a general way of solving the max-min fairness (MMF) traffic objective for WMN using the formulated capacity models. Thus the paper combines WMN radio link modeling with a non-standard way of dealing with uncertain traffic, a combination that has not, to our knowledge, been treated so far by exact optimization models. We discuss several ways, including a method based on the so called compatible or independent sets, of solving the arising MIP problems. We also present an extensive numerical study that illustrates the running time efficiency of different solution approaches, and the influence of the MCS selection options and the number of time slots on traffic performance of a WMN. Exact joint optimization modeling of the WMN capacity and the MMF traffic objectives forms the main contribution of the paper.

Abstract-In this paper, we employ a stochastic geometry model to analyze the transmission capacity of the Decode-andForward (DAF) cooperation scheme in an overlaid wireless network where a primary (PR) network and a secondary (SR) network coexist together. The PR users employ DAF scheme and have a higher priority to access the channel, whereas the SR users use only direct transmission. Because of the fact of coexistence, the interference from SR network seriously affects the performance of PR network. Assuming that simultaneous transmitters in both networks are randomly located in space according to Poisson point processes, we develop outage probabilities for both DAF and direct transmission schemes in both deterministic and Rayleigh fading channels. By defining transmission capacity in terms of the outage probability, a desired data rate and the density of transmissions, we further quantify transmission capacities for both schemes. It shows that the use of cooperative transmission achieves much better reliability and a larger transmission capacity than the use of direct transmission in the PR network. Furthermore, such performance gain can be manipulated to increase the transmission capacity of the SR network without deteriorating the performance of the PR network. Numerical results also demonstrate the significant improvement on the transmission capacity by using cooperative transmission.
