Generating random binary sequences (BSes) is a fundamental requirement in cryptography. A BS is a sequence of $N$ bits, and each bit has a value of 0 or 1. For securing sensors within wireless body area networks (WBANs), electrocardiogram (ECG)-based BS generation methods have been widely investigated in which interpulse intervals (IPIs) from each heartbeat cycle are processed to produce BSes. Using...
Random Binary Sequences (BSs) play an important role in cryptographic algorithms. In order to secure Wireless Body Area Networks (WBANs), electrocardiogram (ECG) signal-based BS generation algorithms were studied in previous papers. These algorithms process Inter-pulse Intervals (IPIs) from the ECG signal, which normally needs about 20 to 30 seconds to generate a 128-bit BS. In order to improve the...
The fuzzy commitment scheme and the fuzzy vault scheme have been widely investigated by researchers in the distribution of symmetric keys within a Wireless Body Area Network (WBAN) for security purposes. Both schemes could use the same physiological signal (Electrocardiogram) for the same purpose (key distribution). To provide guidance to researchers, this paper conducts a comparative analysis of...
In this paper we consider the inter-network interference problem in Wireless Body Area Networks (WBANs). We propose a distributed inter-network interference aware power control algorithm motivated by game theory. A power control game is formulated considering both interference between nearby networks and energy efficiency of WBANs. We derive a distributed power control algorithm called ProActive Power...
In this paper, we propose a non-cooperative power control game to mitigate inter-network interference in Wireless Body Area Networks (WBANs), which use emerging short-range wireless communication technology inside, on or around the human body for healthcare, entertainment and ubiquitous computing purposes. Interference endangers the reliability of WBANs especially in critical medical applications...
Wireless body area networks (WBANs) enable placement of tiny biomedical sensors on or inside the human body to monitor vital body signs. The IEEE 802.15.6 task group is developing a standard to optimize WBAN performance by defining the physical layer (PHY) and media access control (MAC) layer specifications. In this paper an energy efficient MAC protocol (BodyMAC) is proposed. It uses flexible bandwidth...
