Incremental relaying (IR) is known to improve the spectral efficiency of cooperative communication by using the destination feedback. In IR, the relay nodes are employed to assist the source transmission only if it is failed. When the relay nodes perform demodulate-and-forward (DmF), all of them are eligible to forward the source information. This is different from decode-and-forward (DF), where only...
Relay-assisted cooperative communication has received considerable attention as a promising approach to alleviate the burden of installing multiple antennas on simple terminals but still achieving transmit diversity. In most prior work, perfect error detection is assumed to prevent relays that receive in error from forwarding. Since error detection is often performed at the medium access control (MAC)...
This paper proposes a multi-channel token ring protocol (MCTRP) for inter-vehicle communications (IVC). With MCTRP, the emergency messages can be quickly disseminated with bounded delay, and the desired quality-of-service (QoS) for multimedia traffic can be provided with limited hardware requirement and signaling cost. In addition, MCTRP ensures that all nodes have an equal opportunity to transmit...
