Abstract:

The three-handshake broadcast protocol (THBP) was introduced as a single channel synchronous MAC protocol for multi-hop wireless networks. In THBP, a receiver-based conflict detection mechanism as well as a three-handshake process of the control packets was designed to ensure the reliable transmission of broadcast services. By three handshakes of the control packets, it allows nodes to schedule a conflict-free broadcast channel. Within scheduling process, the collisions were detected and reported by the destination nodes. The study shows that the protocol can ensure higher transmission reliability of the broadcast packets with the lower overhead.

Key words: media access control, reliable broadcast services, three-handshake scheduling, a receiver-based conflict detecting mechanism, wireless multi-hop networks
