The computing and networking capacities of today's wireless portable devices allow for pervasive services, which are seamlessly networked. Indeed, wireless handheld devices now embed the necessary resources to act as both service clients and providers. However, the seamless networking of services remains challenged by the inherent mobility and resource(More)
—In this paper, we propose a distributed multi-hop interference avoidance algorithm, namely, IAA to avoid co-channel interference inside a wireless body area network (WBAN). Our proposal adopts carrier sense multiple access with collision avoidance (CSMA/CA) between sources and relays and a flexible time division multiple access (FTDMA) between relays and(More)
In this paper, we present our policy based rule representation for a Diffserv network and show how they are translated and downloaded into the network element. One common problem in specifying rules for policy-based networks is the conflict detection problem, where rules may contradict or duplicate each other. We explore the algorithmic issues related to(More)
Flooding attacks detection in traffic of backbone networks requires generally the analysis of a huge amount of data with high accuracy and low complexity. In this paper, we propose a new scheme to detect flooding attacks in high speed networks. The proposed mechanism is based on the application of Power Divergence measures over Sketch data structure. Sketch(More)
There has been an ever-increasing interest in context-aware computing expressed by the pervasive computing community. Without the presence of context based framework, pervasive systems become more incapable of adapting themselves with the surrounding environment. This article describes a context aware policy-based framework for improves the(More)
The increasing use of wireless networks and the constant miniaturization of electrical devices has empowered the development of Wireless Body Sensor Networks (WBSNs). The wireless nature of the network and the wide variety of sensors offer numerous new, practical and innovative applications to improve health care and the Quality of Life. WBSNs like any(More)
This paper presents our conducting research and describes a new optimal deployment model for medical wireless body area network (WBAN) sensor devices (without mobility) and the relevant possible trade-offs between coverage, connectivity and network life time. We also integrate the effect of interference in wireless medium, and try to devise many-to-one and(More)
WBSNs (wireless body sensor network) like any other sensor networks suffers limited energy and are the highly distributed network, in which its nodes are the organizer itself and each of them has the flexibility of collecting and transmitting patient biomedical information to a sink. When knowledge sent to sink from a path that doesn't have a definite(More)
