Special Issue Information
Dear Colleagues,
Wireless sensor networks play a key role in a wide range of Internet of Things (IoT) scenarios, such as wireless data collection and processing, event detection, target tracking and positioning, and passive wireless perception. Establishing how to better meet the freshness requirements of status update/perception is essential for many IoT applications. In recent years, the age of information (AoI) was proposed to measure the timeliness of the received information from the destination’s perspective. The timeliness of status update/perception is of great importance, especially in real-time monitoring applications, in which the dynamics of the monitored processes need to be tracked accurately for further actions to be taken.
In this Special Issue, the editor aims to present research on AoI-aware wireless sensor networks during the evolution of Internet of Things (IoT) applications to automate business processes and support human efficiency. This Special Issue will cover the implications of the AoI performance metric with existing performance measures of a wireless sensor network, and focus on the basic theory and key technologies of AoI-aware wireless sensor networks. The AoI-related needs/requirements of wireless sensor networks and the services that might address these needs will be a topic of interest. The importance of the AoI metric, the achievable AoI performance limit and the dominating factors, as well as the AoI-guaranteeing mechanism, will also be addressed to shed some light on the AoI-aware wireless sensor network design.
This Special Issue encourages authors from academia and industry to submit new research results related to AoI-aware mechanisms for wireless sensor networks. The topics include, but are not limited to, the following:
- AoI notation and its applications in wireless sensor networks
- AoI notation in wireless sensor networks: time-average age, peak age, information theoretic freshness, age violation probability, data obsolescence function and data freshness function, relationship between AoI and other performance measures
- AoI Analysis and the Achievable AoI Limit
- AoI analysis method: queuing model-based AoI analysis method, Lyapunov optimization-based AoI analysis method, other AoI analysis methods
- Achievable AoI performance limit analysis for wireless networks: the minimum achievable AoI in a one-hop/multi-hop wireless sensor network; the minimum achievable AoI in a wireless multiple access network, a wireless multicast network and a wireless powered network
- Inherent tradeoff analysis: the achievable AoI performance limit of a wireless sensor network and a wireless communication network with the integration of sensing, communication, caching and computing
- AoI-aware applications
- AoI-aware wireless sensing and communication in wireless sensor networks
- AoI-aware signal processing in wireless sensor networks
- AoI-aware edge computing
- AoI-aware scheduling design for wireless sensor networks with heterogeneous traffic requirements
- AoI-aware physical layer security techniques
- AoI-aware resource allocation scheduling for wireless networks.
- Technologies to be used
- Queuing theory
- Optimization theory
- Resource allocation and scheduling
- And many more.
