Service Modeling and Delay Analysis of Packet Delivery over a Wireless Link

A lot of Internet of Things (IoT) applications are time-sensitive, requiring reliable low latency communication (RLLC) or delay guarantee from the underlying wireless network. Fundamentally, this demands service modeling and delay guarantee analysis of data packet delivery over a wireless link. However, few such results are available for IEEE 802.15.4 links, though IEEE 802.15.4 has been the basis for a number of IoT related specifications such as Zigbee and 6LoWPAN. To bridge the gap, an integrated approach is introduced in this paper, which combines empirical models obtained from measurement with analytical models. Extensive experimental investigation under a wide range of settings has been conducted. The effectiveness of the proposed ideas is validated with the experiment results.
