Employing recent wireless technologies, body area network (BAN) interconnects the communications between sensors nearby human bodies and outside world. The sensors collect environmental and physiological data with various importance, therefore, the provisioning of quality of service (QoS) for the sensory data in BAN is a critical issue. This paper proposes MM-QoS, which is a multiple level-based QoS...
Most wireless sensor networks require that every large enough node contain certain properties. By using the Szemeredi's regularity lemma, one can approximate a complex network by a much simpler object in such a way that the approximation is "regular" for most pairs of partitions of this network. After obtaining a more traceable network, we establish bounds for the probability of the property...
In this paper, we proposed an integrated biometric-based security framework for wireless body area networks, which takes advantage of biometric features shared by body sensors deployed at different positions of a person's body. The data communications among these sensors are secured via the proposed authentication and selective encryption schemes that only require low computational power and less...
The spread use of wireless sensor networks (WSNs) in a variety of fields, ranging from the military to environmental protection, has drawn the attention of researchers to this type of networks. Despite their use in interesting applications, such as healthcare and surveillance, many shortcomings derived from their small size and constrained batteries limit their use, calling for solutions to enhance...
