Abstract
Several algorithms implementing the failure detector class \(\diamond{\mathcal P}\) have been proposed in the literature. Regarding communication efficiency, a performance parameter based on the number of links that carry messages forever, algorithms using n links have been proposed, being n the number of processes in the system. In this paper, we show that communication-optimal \(\diamond{\mathcal P}\) algorithms, i.e., using only \({\mathcal C}\) links, being \(2 \le {\mathcal C} \le n\) the number of correct processes, can be implemented. The price to pay for obtaining communication optimality is a higher number of messages exchanged when a failure suspicion occurs. However, one of the algorithms we propose shows that this cost can be linear in n.
