We propose a broadcast protocol that is based on a form of cooperative diversity called the Opportunistic Large Array (OLA). In the initial broadcast, an SNR ("transmission&qu...
Specific applications like military or public emergency ones require secure group communication in ad hoc environments. The most suitable solution to provide the expected level of...

Abstract. The mutual exclusion protocol presented ensures that whatever perturbation the network undergo, it regains consistency in nite time: one and only one privilege token is p...
In this paper we describe an efficient algorithm for the management of group-keys for Group Communication Systems. Our algorithm is based on the notion of key-graphs, previously u...
Congestion control protocols rely on receivers to support fair bandwidth sharing. However, a receiver has incentives to elicit self-beneficial bandwidth allocations and hence may ...
