Center node: "availability aware cell association for hybrid power supply networks with adaptive bias"
  Abstract: New challenges have emerged from the integration of renewable energy sources within the conventional electrical grid which powers base stations (BS) and traffic offloading brings a promising solution to maintain the network performance while reducing the carbon footprint. In this work, we consider a three-tier downlink cellular network consisting of on-grid, off-grid and hybrid BSs, and design a novel power-aware biased cell association where each user partitions BSs into two sets, regardless of their effective tier but based on the type of power, renewable or not, that can be requested for service. Then, a different association bias is applied for each set. To capture their dual nature, the bias applied for association with a hybrid BS is not constant among users, nor over time, and is dynamically tailored to the fluctuations of the BS battery level, the user power requirement and the estimated power consumed to serve other users potentially associated with the same BS. Next, we develop for such strategy a tractable performance analysis, using stochastic geometry, and investigate the biases minimizing the grid power consumption. The proposed cell association allows to efficiently share the available energy among BSs and takes advantage of higher heterogeneity in the BS powering.
