End-to-End Delay Analysis of Wireless ECG over Cellular Networks

摘要

In this paper, we present a medical-grade network architecture based on the wireless cellular technology of CDMA2000 1xEV-DO (Evolution-Data Optimized). It can provide highly reliable communication with a bounded delay by exploiting its inherent channel access structure and cooperative packet scheduler at the access network. Additionally, we propose a way of analyzing the worst-case end-to-end delay over the candidate cellular architecture, and apply it to wireless ECG (Electrocardiogram) to examine its applicability. Our simulation study shows how the proposed architecture can provide acceptable quality of service for wireless medical applications.
