One emerging application for Wireless Sensor Networks (WSNs) involves their use in healthcare where they are generally termed Wireless Medical Sensor Networks (WMSNs).
In current healthcare applications, there are many problems concerning security policy violations such as unauthorised denial of use, unauthorised information modification and unauthorised information release of medical data in the real world environment.
Current WSN access control models use the traditional Role-Based Access Control (RBAC) or cryptographic methods for data access control, but the systems still need to predefine attributes, roles and policies before deployment. However, it is difficult to determine in advance all the possible needs for access in real world applications because there may be unanticipated situations at any time.
This research explores possible approaches to address these issues and to develop a new access control model to fill the gaps in work done by the WSN research community.
To address the conflict between data availability and data privacy, this research proposes the Trust-based Adaptive Access Control (TBA2C) model that integrates the concept of trust into the previous model.
