Quiescent Consensus in Mobile Ad-hoc Networks using Eventually Storage-Free Broadcasts

Lookup NU author(s): Francois Bonnet, Dr Paul EzhilchelvanORCiD, Einar Vollset



We solve the consensus problem using a new class of broad-casts that are very appropriate to ad-hoc networking: every broadcast message is eventually ensured to be garbage-collected,thus freeing buffers in the resource-constrained mobile devices. We identify an impossibility result, the conditions in whicha consensus protocol that assumes normal, message-keeping broadcasts can work using the new broadcast, and the adaptation such a protocol would require when these conditions do not hold. The cost of achieving quiescent consensus, estimated through simulations, is shown to be affordable for hosting practical dependable applications.
