Recently, the way people consume video content has been undergoing a dramatic change. Plain TV sets, that have been the center of home entertainment for a long time, are losing grounds to Hybrid TV’s, PC’s, game consoles, and, more recently, mobile devices such as tablets and smartphones. The new predominant paradigm is: watch what I […]
Read moreWe consider wireless sensor networks (WSNs) used for distributed estimation of unknown parameters. Due to the limited bandwidth, sensor nodes quantize their noisy observations before transmission to a fusion center (FC) for the estimation process. In this letter, the correlation between observations is exploited to reduce the mean-square error (MSE) of the distributed estimation. Specifically, […]
Read moreWe propose a framework to bridge the gap between secure authentication in automotive networks and on the internet. Our proposed framework allows runtime key exchanges with minimal overhead for resource-constrained in-vehicle networks. It combines symmetric and asymmetric cryptography to establish secure communication and enable secure updates of keys and software throughout the lifetime of the […]
Read moreTo increase the energy efficiency of Ethernet networks, in 2010, the IEEE published the IEEE 802.3az amendment, known as Energy Efficient Ethernet (EEE). The amendment introduces a new operational mode, defined as Low Power Idle (LPI), that allows to considerably reduce the power consumption of inactive Ethernet links. In this paper, we address the application […]
Read moreFor efficient and reliable data transmission, the traffic load should be as uniformly distributed as possible in the network, and the average distance traveled by the data should be short. This criterion has been shown to be fundamental. The key design problem is therefore to find the optimal solution that achieves this criterion. With a […]

An Opportunistic Transmission Protocol for Body Sensor Networks using RSSI and on-board accelerometer
Inter-communication between nodes in Body Sensor Networks can be interrupted by body movement. Body parts can reflect and absorb radio frequencies or block the radio signal that can disrupt the radio communication. In this paper, we have proposed an opportunistic radio transmission that uses the Received Signal Strength Indicator as feedback mechanism to improve the […]
Read moreRelay nodes (RNs), as important components of heterogeneous networks introduced in Long-Term Evolution-Advanced systems, are employed to improve network capacity and extend cell coverage in a cost-effective manner. In heterogeneous relay networks, there are two types of user access connections: the direct link and the two-hop link. The former is used when a user accesses the […]
Read moreAutonomous Unmanned Aerial Vehicles (UAVs) have gained popularity due to their many potential application fields. Alongside sophisticated sensors, UAVs can be equipped with communication adaptors aimed for inter-UAV communication. Inter-communication of UAVs to form a UAV swarm raises questions on how to manage its communication structure and mobility. In this paper, we consider therefore the […]
Read moreThe correct inference of gene regulatory network plays a critical role in understanding biological regulation in cells and genome based therapeutics. DNA microarray is the most widely used technology for extracting the relationships between thousands of genes simultaneously. Since S-system is based on the rate law, it is considered as a suitable mathematical model for […]
Read moreTo be successful in the 21st century, students must have a fundamental knowledge of complex networks which allows them to explore the interconnectedness of our world. Network science, a relatively new field of study, represents a fundamental shift away from reductionism to a more complex real world approach to problem solving which looks at interactions between […]
