Abstract

The Broadcast Communication Model (BCM, for short) is a distributed system with no central arbiter populated by p stations denoted by S(1), S(2), ..., S(p) that communicate by transmitting messages on a communication channel. The stations are assumed to have the computing power of a laptop computer and to be synchronous驴in particular, they all run the same program, albeit on different data. We assume that a station is expending power while transmitting or receiving messages. As it turns out, one of the most effective energy-saving strategies is to mandate individual stations to power their transceiver off (i.e., go to sleep) whenever they are not transmitting or receiving messages. Suppose that the p stations of the BCM store collectively n items such that station S(i), (1
