Brief announcement: Hardness of broadcasting in wireless networks with unreliable communication

We prove two broadcast lower bounds for a wireless network model that includes unreliable links. For deterministic algorithms, we show n − 1 rounds are required, where n is the number of processes. For randomized algorithms, ε(n − 1) rounds are required for success probability ε. In both cases, the bounds are proved for a network in which constant-time broadcast is possible
