Abstract [en]

Many emerging applications using wireless networks imply high requirements on reliability, but also on a predictable maximum delay. Due to cost constraints and interoperability with existing networks, half-duplex time division multiple access (TDMA) is typically used in these applications. With TDMA, channel access is upper-bounded and the jitter can be set to zero. However, the major drawback of TDMA is that the already-allocated time-slots are wasted if their respective transmitters do not have any packet to send. Therefore, in this paper we propose a novel cluster-relaying scheme to overcome this drawback but still reduce the probability of error given a certain deadline. Numerical results show that the proposed scheme significantly enhances reliability while guaranteeing deadline for each message.
