QoS supported MAC for arbitrary networked control in home networks

DOI

Description

Home appliances can be connected in a ubiquitous manner by communication networks. In addition to the operation sensing of home appliances, appliance management via sending control messages will be needed. The control operations include power adjustment of home appliances and sampling rate change of a sensing device. It should be noted that control messages differ from sensing data and the former generally require more reliability. In this paper, we study the delay performance of control messages at MAC (Media Access Control) layer in the network with shared communication media. The proposed approach can confine the delay uncertainty of the control messages within a specified tolerant time for respective appliance.
