Abstract

Wireless body area networks (WBANs) is a technology that offers better methods for real-time patient health monitoring. By the year 2025, industry and academia estimate up to 3 billion wearable sensors placed in different WBANs, gathering health data from patients and sending them to medical servers. However, data transmission from WBANs to those medical servers is still a challenging task. In particular, wireless transmission can result in high latency and low throughput due to interference, which causes risks to healthcare patients. The existing solutions address wireless transmission interference inside the same WBAN or the interference that one WBAN can make on another. These solutions rarely cope with both interferences from a medical application perspective. In this article, we detail PDAC, a medical application-aware MAC-layer P rotocol for D ynamic Channel A lloC ation. At a glance, PDAC takes advantage of the existence of multiple base stations in the most common wireless network environments. In this sense, it orchestrates the cooperation among base stations, even in dense medical-hospital environments, by properly allocating co-located wireless body area networks. PDAC relies on a greedy solution for a graph coloring problem to reduce interferences and enhance data communication. According to evaluations, we observe an average increase of 30% on the system throughput and an average reduction of 40% in the system latency when compared to a baseline solution.
