We consider wireless communication networks where service rates of nodes depend the loads of their neighbours. We demonstrate that these rates are utility-maximising in a certain sense. Using this observation, we prove stability of single-hop networks under natural assumptions. We also obtain bounds on some moments of the stationary workload.
In order to obtain these results, we consider a framework of utility-optimising rate allocations which is much more general than the well-known $\alpha$-fairness, and prove general results on stability and bounds for some stationary workload distributions in networks with these rate allocations.
We also discuss stability of infinite networks.
