mobile ad hoc network (MANET), reliable broadcast


Reliable broadcast is an important operation in mobile ad hoc networks (MANETs) (e.g., giving orders, search ing routes, and notifying important signals). However, using a naive flooding to achieve reliable broadcasting may be very costly, causing a lot of contention, colli sion, and congestion, to which we refer as the broad cast storm problem [1]. This paper proposes an efficient reliable broadcasting protocol by taking care of the po tential broadcast storm problem that could occur in the medium-access level. Existing protocols are either unre liable [1, 2, 3, 4, 5, 6], or reliable [7, 8] but based on a too costly approach. Our protocol differs from existing protocols by ensuring reliability but adopting a low-cost unreliable broadcast as a basic operation. Simulation re sults do justify the efficiency of the proposed protocol.
