Resource scheduling based on routing tree and detection matrix for Internet of things

Abstract

Effective scheduling of limited communication resources is one of the critical methods for data transmission in the Internet of things. However, the time slot utilization rate of many existing resource scheduling methods of Internet of things is not high. This article proposes a new efficient resource scheduling based on routing tree and detection matrix for Internet of things. In heterogeneous Internet of things, according to the different working modes and functions, the nodes are divided into Internet of things devices, routing nodes, and base station. We use time slot multiplexing to improve the time slot utilization of continuous transmission in Internet of things. First, the time slot allocation table in a round is obtained by the time slot scheduling based on the routing tree. Then, the collision matrix and the transmission matrix are established based on the time slot allocation table in a round. Finally, the minimum time slot scheduling in continuous rounds is determined based on the routing tree and the detection matrix. The experimental results show that the resource scheduling based on routing tree and detection matrix effectively improves the utilization of time slots and improves the throughput of the Internet of things.

Resource Scheduling Based on Unequal Clustering in Internet of Things

“…ere are two typical transmission interference models, namely, the graph-based protocol model and the SINRbased physical model. RSUC is based on the graph-based protocol model, which includes primary conflict and secondary conflict [34]. e primary conflict of the graph-based protocol model affects the range between one-hop neighbors.…”
