“…The home server may integrate this information with a local database for user inspection, or it may further be forwarded to a medical server. Similarly, the idea of embedding medical devices with hospital information system is presented in [34]. The integration of ubiquitous echograph with the home information network make it very easy for the doctors to immediately diagnose the patients.…”

In wireless body area sensor networks (WBASNs), energy efficiency is an area of extreme significance. At first, we present a mathematical model for a non-invasive inductive link which is used to recharge the battery of an implanted biomedical device (pacemaker). Afterwards, we propose a distance-aware relaying energy-efficient (DARE) and mutual information-based DARE (MI-DARE) routing protocols for multihop mobility-aware body area sensor networks (MM-BASNs). Both the routing protocols and the non-invasive inductive link model are tested with the consideration of eight patients in a hospital unit under different topologies, where the vital signs of each patient are monitored through seven on-body sensors and an implanted pacemaker. To reduce energy consumption of the network, the sensors communicate with a sink via an on-body relay which is fixed on the chest of each patient. The behavior (static/mobile) and position of the sink are changed in each topology, and the impact of mobility due to postural changes of the patient(s) arms, legs, and head is also investigated. The MI-DARE protocol further prolongs the network lifetime by minimizing the number of transmissions. Simulation results show that the proposed techniques outperform contemporary schemes in terms of the selected performance metrics.

“…In particular, many manufacturers like AeroScout [2], Ekahau [3], or Honeywell [21] support various commercial products for mobile asset management in a real-time location system (RTLS). Therefore, indoor MAM systems require technologies for location detection and real-time tracking of numerous mobile devices that have frequent mobility in the narrow space of a building.…”

A tracking service like asset management is essential in a dynamic hospital environment consisting of numerous mobile assets (e.g., wheelchairs or infusion pumps) that are continuously relocated throughout a hospital. The tracking service is accomplished based on the key technologies of an indoor location-based service (LBS), such as locating and monitoring multiple mobile targets inside a building in real time. An indoor LBS such as a tracking service entails numerous resource lookups being requested concurrently and frequently from several locations, as well as a network infrastructure requiring support for high scalability in indoor environments. A traditional centralized architecture needs to maintain a geographic map of the entire building or complex in its central server, which can cause low scalability and traffic congestion. This paper presents a self-organizing and fully distributed indoor mobile asset management (MAM) platform, and proposes an architecture for multiple trackees (such as mobile assets) and trackers based on the proposed distributed platform in real time. In order to verify the suggested platform, scalability performance according to increases in the number of concurrent lookups was evaluated in a real test bed. Tracking latency and traffic load ratio in the proposed tracking architecture was also evaluated.

“…However, as discussed in the introduction, to equip them on conventional vital sign sensors is not cost effective. Although a sensor equipped CCD, such as a digital camera, can utilize the barcode as the patient identification without any hardware modification [51], no conventional sensors can read them without hardware modification. For small vital sign sensors, such as thermometers and pulse oxymeters, to equip readers is not plausible.…”
