— A Wireless Sensor Network (WSN) is formed by a large quantity of small devices with certain computing power, wireless communication and sensing capabilities. These types of networks have become popular as they have been developed for applications which can carry out a vast quantity of tasks, including home and building monitoring, object tracking,(More)
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above 6 x 10(19) electron volts and the positions of active galactic nuclei (AGN) lying within approximately 75 megaparsecs. We rejected the hypothesis of an isotropic distribution of these(More)
This chapter describes the implementation and performance evaluation of a novel routing protocol called Pandora, which is designed for social applications. This protocol can be implemented in a broad number of devices, such as commercial wireless routers and laptops. It also provides a robust backbone integrating and sharing data, voice and video between(More)
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6×10 19 eV by analyzing cosmic rays with energies above E ≥ 5×10 18 eV arriving within an angular separation of approximately 15 •. We characterize the(More)
The above figure shows the HESS TeV gamma-ray survey of the Galactic plane. Thirty-nine sources of TeV gamma rays are detected in the Galactic plane, including supernova remnants, pulsar wind nebulae, X-ray binary systems, molecular clouds, and unidentified sources.

This article examines the importance of wireless ad hoc networ�s and the Location Routing Algorithm with Cluster-Based Flooding (LORA-CBF) for inter-vehicular communication in the context of optimizing traffic flow and increasing motorway safety. The LORA-CBF routing algorithm is discussed and simulated in detail, considering a motorway environment with its(More)
