Shrnutí:We study the problem of distributed construction of efficient de-centralized communication schedules for ad-hoc wireless networks. We consider a model which is close to real scenarios: (1) the SINR interference model, which covers most important distinctive features of contemporary wireless communication, such as signal fading, collisions and accumulation of signal, and (2) any underlying metric of bounded growth, which includes Euclidean space with certain type of obstacles. Most of efficient solutions in the SINR model rely on probabilistic algorithms, assuming access of nodes to the sources of independent truly random bits, which in practice is hard to get by wireless devices.In this paper we show that key efficient de-centralized communication abstraction primitives, such as aggregation and broadcast schedules (which are bases of many other communication tasks), can be efficiently built by distributed algorithms in SINR networks without using any randomization. In particular, the length of the built communication schedules are asymptotically as efficient as those significantly relying on randomization, and close to the theoretic lower bounds. Importantly, the time (round) complexity of our solutions grows only logarithmically with respect to the growth of the density of a network, which makes them scalable in real-life scenarios.
