An Energy Preserving Practical Security Assessment on Wireless Body Area Networks

Securing private data is the concern of every network user, especially if these users are patients who seek medical attention and constant vitals monitoring. So, a dedicated set of wearable devices that are connected wirelessly to a medical care institution are the simplest definition of a Wireless Body Area Network, which gives a patient the freedom of movement while certain organs are constantly monitored. Securing the system against attacks on data transmitted puts an overhead to the users and developers of these networks. A procedure called Practical Security Assessment is a technique used to set security measures to detect attacks on the network. Almost all security procedures add energy consumption of nodes in a network and some are not guaranteed to be efficient enough. In this research, PSA was tested and proven to minimize the increment in energy consumption over a defined distance between nodes to guarantee legitimate nodes are the only ones that are connected.
