Wireless sensor networks (WSNs) are usually randomly deployed in a region of interest. As a result, algorithms that can compute the location of sensor nodes within a WSN are needed. In recent years, several localization algorithms have been proposed for stationary WSNs. However, most studies only provide simulation results and most algorithms have never been implemented on a real testbed. In this...
One of the main requirements in the design and development of wireless sensor networks (WSN) is to minimize their power consumption. For this reason, this paper focuses on the energy efficiency improvement that can be achieved using new communication methods called cooperative communications. This cooperative communications is a diversity technique that is aiming to maximize the total network capacity...
Federating Wireless Sensor Networks (WSNs) in Outdoor Environment Monitoring (OEM) becomes a necessity as advances in sensing technologies are achieved. Where several WSN sectors pursuing identical/different tasks intend to collaborate with each other in order to achieve more sophisticated and challenging missions, or intend to recover a significant damage in the network. Connecting (federating) these...
