Directional radio propagation measurements for near-ground peer-to-peer networks

Sensor networks, that consist of potentially several thousands of nodes each with sensing (heat, sound, light, magnetism, etc.) and wireless communication capabilities, provide great opportunities for monitoring spatial information about a region of ...

This paper presents the concepts of ubiquitous sensor networking. It envisages the existence of numerous independent sensor networks. The networks gather information about physical phenomena and collaborate with wide area mobile networks to provide more ...

Barrier coverage is an important problem for sensor networks to fulfill some given sensing tasks. Barrier coverage guarantees the detection of events happened crossing a barrier of sensors. In majority study of barrier coverage using sensor networks, ...
