Instant DNA analysis on a chip

University of Virginia (U.Va.) professor James Landers is known as 'a master of compression' because he has reduced an entire laboratory for DNA analysis to a chip the size of a common everyday microscope slide. His future handheld device may allow 'physicians, crime scene investigators, pharmacists, even the general public,...

Rational Swarm Routing for Mobile Ad-Hoc Wireless Networks

Wireless Mobile Ad-hoc NETworks MANET require dynamic routing schemes for adequate performance. This paper introduces a new dynamic routing scheme based upon stigmergy. In a similar manner to ant-colony based dynamic routing protocols, this scheme is able to respond to link quality changes after a path is established. However, load...

Dynamic Security and QoS Adaptation in Real-Time Embedded Systems

A number of Real-Time Embedded Systems RTESs are used to manage critical infrastructure such as electric grids or C4I systems. In these systems, it is essential to meet deadlines, for example, to avoid a power outage or loss of a life. The importance of security support is also in-creasing, because...

Fair QoS-Aware Adaptive Routing and Wavelength Assignment in All-Optical Networks

In all-optical networks with no wavelength conversion, signals must travel on the same wavelength over possibly very long distances. During transmission, the QoS of signals as measured by their Bit Error Rates is degraded not only by the propagation through fibers, but also by small optical leaks from other signals...

On Scheduling and Real-Time Capacity of Hexagonal Wireless Sensor Networks

Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate time slots to the nodes of a network such that if the nodes transmit only during the allocated time slots, no collision occurs. For real-time applications, by...
