Mobility enhancement of patients body monitoring based on WBAN with multipath routing

Abstract

One of the promising applications of wireless sensor networks (WSNs) is monitoring of the human body for health concerns. For this purpose, a large number of small sensors are implanted in the human body. These sensors altogether provide a network of wireless sensors (WBANs) and monitor the vital signs and signals of the human body; these sensors will then send this information to the doctor. The most important application of the WBAN is the implementation of the monitoring network for patient safety in the hospital environment. In this case, supporting patients' mobility is one of the basic needs, which has been underestimated in recent studies. The problem that involves providing the required energy for the units used in this type of network is challenging; for this reason, sent/ received units with very low power consumption and with a very small radius are used in order to save energy. The resulting small sending range, leads to the lack of support for patients' mobility. In this paper, the AD HOC mode is suggested for use to establish a network and a multi-path routing algorithm, for the purpose of importing patients' mobility in hospital setting. The results of the simulation show that in addition to supporting patients' mobility, the use of the proposed idea instead of previously presented protocols, reduces delays in data transmission and energy consumption; and it also increases the delivery rate depending on the destination and the lifetime of the network, while on the other hand, it increases routing overhead.

“…Os resultados mostram melhor desempenho em comparação ao AODV e AOMDV. Birgani et al [17] apresentam o Reliable Multi-path Routing (RMPR) que utiliza a camada física da rede para construção das rotas.…”

Challenges in Wireless Body Area Network

“…One of the major issues is to reach to sink, which may be single or multi hop. Collier et al in [13] show that may not stick to single strategy and can find which one is better for the particular case. The same may be applied to optimize the hop count.…”

An efficient approach for the detection of link failures in WBAN system for health care applications

“…Essafi et al adopted the dynamic routing protocol collection tree protocol (CTP) to ensure the connectivity and the reliability of the data transmissions in the WBAN. Another protocol “reliable multi‐path routing” (RMPR) proposed in Birgani et al discovered and corrects route to the destination (sink) in order to reduce the delay and the packet loss rate. A dynamic routing protocol could not be efficient for the very rapid movement of the body, for example, when the body is in “running” state.…”
