Simplifying Itai-Rodeh leaderelection for anonymous rings
We present two probabilistic leader election algorithms for anonymous unidirectional rings with FIFO channels, based on an algorithm from Itai and Rodeh. In contrast to the Itai-Rodeh algorithm, our algorithms are finite-state. So they can be analyzed using explicit state space exploration; we used the probabilistic model checker PRISM to verify, for rings up to size four, that eventually a unique leader is elected with probability one. Furthermore, we give a manual correctness proof for each algorithm.
