Sensing Systems for Radio Context Awareness

Call for Papers

Context regards “any information that can be used to characterize the situation of an entity, where an entity can be a person, place, or physical object.” Radio context awareness regards the ability of detecting and estimating a radio system state or parameter, globally or in one of its components, in order to enhance communication performance at the physical, network, or application layers. Channel state information, energy consumption, environment mapping, mutual interference among active devices, and spectrum usage are examples of system state information that can enhance either the efficiency of the communication network itself or the effectiveness of the related application. It is worth to notice that also part of the well-known radio cognitive process can be situated in this area.

Sensing systems, responsible for the detection and estimation tasks, are supposed to corroborate the potential development of various forms of awareness in the communications scenario in terms of technical characteristics, costs, and performance. They can be implemented in numerous technological solutions, architectures, and topologies, from the single sensor to networks with a large number of devices, as in wireless sensor networks.

Nowadays, it is clear that radio context-aware techniques can give a further strong impulse to new applications and enhance communication performance operating on several aspects of the system; as relevant examples, we mention the interference management, the resource optimization, and the growing interest in the field of energy efficiency in communication infrastructures.

In this special issue, we particularly take an interest in manuscripts that investigate models for radio context awareness, systems able to generate and manage radio awareness, and applications made possible by these advanced functions. Potential topics include, but are not limited to:

• Radio context-aware and cognitive models
• Sensing systems for context-aware and cognitive radio
• Distributed computing and collaborative techniques for sensing systems
• Sensing systems for energy savings and management in communication infrastructures
• Novel radio cognitive and context-aware applications
• Adaptive context-based sensors interactions
• Wireless sensor networks
• Resource and energy management in sensor networks
• Data fusion in sensor networks
• Learning techniques and strategies in sensing systems
• Network issues in sensing systems for context awareness (protocols, routing, metrics, etc.)
