摘要：

UM-BUS, a reconfigurable high-speed device interconnected bus, has been proposed to enable lightweight sensor system deployment in IoTs. Performance prediction is a key step to build an idea of the worst or best cases before real world deployment of UM-BUS-based systems. This paper proposes a queuing theory guided analytic model which allows us to obtain an approximation for the average packet delay as well as upper and lower bounds. Furthermore, a Revive Interval (RI)-based technique is proposed to establish a dynamic logical cycle frame to involve only active nodes so as to improve the bus efficiency. A set of experiments based on MATLAB simulation are conducted to evaluate the bus performance. The proposed dynamic cycle frame scheme is validated to be effective for a high performance and low power design. (C) 2019 Elsevier Inc. All rights reserved.
