Description

In this paper we propose an alternative probabilistic protocol for relaying wireless network. Usually, the communication protocols are designed to be deterministic when it comes to the order of retransmission from the communication nodes. In contrast, we propose an alternative probabilistic protocol where the retransmitting nodes are chosen probabilistically, and which allows easier performance optimization. Using Monte Carlo simulations, we will show at which location of the Relay do we get the best performance. Due to energy consuming concern and due to lower complexity advantage, as required in technologies such as Internet of Things (IoT), we will consider the case when Relay works on the Demodulate-and-Forward (DMF) mode, while for the destination we focus on the case when the receiver performs combining.
