Abstract

The MANET liveness property ensures that any partition in an ad hoc network is not permanently isolated. For networks that fulfil the property a few crash-tolerant broadcast protocols have been proposed. However, it has also been proved that the minimum time of direct connectivity between nodes, and thus the correctness of the protocols, depends on the total number of hosts in a network and on the total number of messages that can be disseminated by each node concurrently. In this paper, we propose an improved version of the reliable broadcast protocols that works correctly, even though the minimum time of direct connection between nodes allows them to exchange (send and respond to) at least only two messages, making the correctness of this protocol independent of system parameters.
