SUMMARY In wired networks, broadcast and multicast transmissions can be easily achieved by data link layer (layer 2). Nevertheless, it is a big challenge to safely transfer broadcast or multicast data frames over multi-hop mobile ad hoc networks (MANETs) due to the high bit error rate, the high collision probability and the lack of acknowledgment. Additionally, most of MANET's routing protocols...

We present an innovative approach to the design of faultprocessors agree on exactly the same sequence of broadcast tolerant distributed systems that avoids the several rounds of message exchange required by current protocols for consensus agreement. The messages. approach is based on broadcast communication over a local area It is easy to demonstrate that placing a total order on network, such ...

Zeng), [email protected] Multi-hop broadcast is a key technique to disseminate time-sensitive event-driven safety warning messages (WMs) in Vehicular Ad hoc Networks (VANETs). Due to the lossy nature of...

Wireless communications are becoming an important part of our everyday lifestyle. One major area that will have an enormous impact on the performance of wireless ad hoc networks is the medium access control (MAC) layer. Current random access MAC protocols for ad hoc networks support reliable unicast but not reliable broadcast. In this paper, we proposed a random access MAC protocol, Broadcast S...
