Cognitive Wireless Sensor Network Platform for Cooperative Communications

Cooperative method for wireless sensor network localization

In order to obtain an efficient wireless sensor network localization, several enhancements based on the decentralized approach are proposed. These features can be used in the cases when multiple distance measurements are used as input, where each node iteratively updates its estimated position using a maximum likelihood estimation method based on the previously estimated positions of its neighb...

Wireless Sensor Network Platform for Autonomous Experimentation

FACULTY OF ENGINEERING, SCIENCE AND MATHEMATICS SCHOOL OF ELECTRONICS AND COMPUTER SCIENCE by Robert D. Spanton Developments in wireless sensor networks (WSNs) are strongly focused on minimizing the power requirements of sensor nodes. As sensors with significantly large resource requirements are introduced into WSN systems, algorithms must be developed to maximise the information returned per s...

Cooperative Communications for Wireless Ad Hoc and Sensor Networks

Wireless sensor network design through genetic algorithm

In this paper, we study WSN design, as a multi-objective optimization problem using GA technique. We study the effects of GA parameters including population size, selection and crossover method and mutation probability on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication...

Cooperative Communications with Network Coding for Wireless Uplink Channels

Future wireless systems are characterized by large user capacity, high speed, high reliability. Yet, inherent fading and interference of wireless communications render these design objectives challenging. As an efficient and inexpensive method to combat wireless fading, cooperative communications ([1], [2]) has recently attracted lots of research efforts and practical implementations. The princ...
