1. Introduction
Let L be a set of wireless links, each link i ∈ L characterized by a sender node si and a receiver node ri. Depending on the spatial disposition of such nodes, activating more than one link simultaneously creates interference that may hamper the receivers’ ability to decode what they receive. In the physical interference model [1], the chief quantity governing receiver ri’s ability to decode what it receives from si when all links of a set S containing link i are active is the signal-to-interference-and-noise ratio (SINR), given by where P is a sender’s transmission power (assumed the same for all senders), N is the noise floor, dab is the Euclidean distance between nodes a and b, and α > 2 determines the law of power decay with Euclidean distance. We say that a nonempty subset S of L is feasible if no two of its members share a node (in case |S| > 1) and moreover SINR(i, S) ≥ β for all i ∈ S, where β is a parameter related to a receiver’s decoding capabilities (assumed the same for all receivers) and is chosen so that β > 1. Several strategies have been devised to maximize network capacity, either through the self-contained scheduling of the links in L for activation [2–20] or by combining link scheduling with other techniques [21–29]. All these strategies revolve around formulations as NP-hard optimization problems, so all rely on some form of heuristic procedure drawing inspiration from various sources, some more of an intuitive nature [3–7,9,10,12–17,19–24,26,28], others more formally grounded on graph-theoretic notions [2,8,11,18,29]. Often the problem is formulated in a spatial time-division multiple access (STDMA) framework, that is, assuming essentially that time is divided into time slots, each one accommodating a certain number of simultaneous link activations. In this case, the problem is to find T feasible subsets of L, here denoted by S1, S2, . . ., ST , minimizing T while ensuring that every link appears in exactly one of the T subsets.
