The rapid uptake of the Wireless Body Area Networks (WBAN) and their services poses unprecedented security requirements. WBAN are evolving to support these requirements. Fulfilling these tasks is challenging as their mobile context is increasingly complex, heterogeneous, and evolving. One potential solution to meet the WBAN security requirements is trust management that helps to reach a more secure and adaptable WBAN environment. Accordingly, this article aims to serve as a brief survey of trust management approaches within intra-WBAN and inter-WBAN. For that, we first summarize trust management concepts, discuss WBAN challenges and classify the attacks on WBAN trust management models. Subsequently, we detail and compare the existing trust based approaches in a WBAN context. We pinpoint their limitations and provide a new classification of these different approaches. We also propose a set of best practices that may help the reader to build a robust and an efficient trust management framework. We complete this survey by highlighting the open future directions and perspectives for research.

“…Patients carry a batch of sensor nodes attached to their bodies. Each sensor node collects one or more bio physiological parameters, which are used to evaluate the overall health state of a given patient [25,26]. To improve the quality-of-life of hospitalized patients it is important to offer them free walking around the perimeter of an infirmary.…”

International audienceThe use of wireless sensor networks (WSNs) isgrowing up in the last few years. Therefore, new challengesarise every day and one of the emerging challenges in WSNsis the nodes mobility support. This feature increases theapplication areas of these technologies but also raises newchallenges to solve. This paper proposes a new handovermechanism, called Hand4MAC (Handover mechanism forMAC layer supporting continuous communication in mobilewireless sensor networks), to deal with body sensorsmobilityin scenarios where patients are hospitalized. This approachtries to provide continuous monitoring and communicationwith these sensor nodes when they move across differentaccess points wireless coverage range. The proposed methodfor medium access control (MAC) layer considers that nodesremain within the same network. The evaluation study of theproposed algorithm was performed by simulation and evaluatedin comparison with the well-known RSSI-based handoveralgorithm. Itwas concluded that Hand4MAC performsbetter and reveals promising results for real deployment

Wireless body area networks (WBANs) are composed of small intelligent tiny wireless sensors; these sensors are responsible for collecting information of a patient's vital signs and transmitting vital information. WBAN offers mobility to patients and flexibility to medical staff. An increase of the deployment of monitoring systems on patients promotes researchers and developers to focus on issues related to WBAN. Quality of service (QoS) has been always treated as a major issue in WBAN technology, and scheduling as a packet prioritizing mechanism contributes to QoS guarantee provisioning significantly. In this paper, two novel inter-WBAN data scheduling and aggregation are developed for monitoring systems in order to satisfy QoS requirements in WBAN networks. We introduced a novel parameter called critical delay to serve packets taking into account their priorities and classify them into an aggregated frame to be further transmitted to medical server. The proposed scheme provides QoS-guaranteed service for the applications running on the sensor nodes in all the three aspects of QoS, that is, delay, throughput and packet loss.
