Distributed Collision-Free Message Broadcasting in Multichannel Wireless Networks

Broadcasting is essential in many wireless network applications. The main problem of broadcasting in a wireless network is the broadcast messages may collide with other transmissions. Normally, no acknowledgement (ACK) message is sent back on receipt of broadcast packet, thus, the source node cannot determine if the broadcast is successful. In this paper, a mechanism that ensures collision-free message broadcasting in a multichannel wireless network is provided.
