WebStoller’s Leader Election Algorithm Abstract In 1997, Stoller presented a leader election algorithm for a syn-chronous system with crash failures. The algorithm is an adaptation of Garcia-Molina’sBully Algorithm that uses failure detectors in-stead of explicit timeouts. Since the characteristics of the algorithm Web12 mrt. 2012 · Try to think through your suggested random approach executing in a system with five nodes (processes/computers). Which node will make the random decision? Before you can decide that, you must have a leader. If all nodes try to choose randomly at once, they will come up with different answers, and no leader will be jointly recognized.
