Special Issue Information

Dear Colleagues,

Environmental sensing technology has reduced in size and cost and can now be deployed at many points across a city where it would have been impractical only a few years ago. Mobile technology has advanced to provide robust connectivity solutions, enabling these sensors to be deployed and exploited efficiently and effectively by city authorities and other bodies. Environmental monitoring can exploit IoT sensors, smartphones, UAVs and vehicles to measure many parameters in cities, the countryside, rivers, lakes and the sky, including air and water quality, weather, noise, traffic, smoke and crowding. As these systems grow in complexity, greater capability and flexibility are gained by extending the autonomy of system processes. With data processing close to the edge, quick responses to events are better assured, and with processing deployed across layers from the edge to the cloud, resilience and security are increased. Edge data analytics is gaining major importance, advocated to cope with the surge in IoT data, enabling fast and privacy-preserving computation. This Special Issue aims to investigate the design, implementation, deployment, operation and evaluation of mobile systems and solutions for environmental sensing with an emphasis on solutions that can synergistically leverage techniques and insights from the domains of sensing, networking, scalable computing and artificial intelligence (AI) technologies. Clearly, we are not only considering the so-called first world as the scenario for this evolution; we also refer to those areas where ICT is currently less widespread, hoping that it may represent a societal development opportunity rather than a source of further divides.

The topics of interest include but are not limited to:

  • Wearable computing, sensing and context awareness;
  • The management, configuration and deployment of systems supporting mobility;
  • Data management and analytics at the edge;
  • Mobile and pervasive systems with elements of networked sensing;
  • Decentralized learning algorithms and models for environmental intelligence;
  • Geospatial data analytics and algorithms;
  • Environmental modelling and mapping;
  • Data mining, machine learning and AI techniques for spatial–temporal analytics;
  • Public mapping for better citizen engagement;
  • Collaborative sensing, networking and computing.

Cluster computing has attracted much attention as an effective way of solving large-scale problems. However, only a few attempts have been made to explore mobile computing clusters that can be easily built using commodity smartphones and tablets. To investigate the possibility of mobile cluster-based rendering of large datasets, we developed a mobile GPU ray tracer that renders nontrivial 3D scenes with many millions of triangles at an interactive frame rate on a small-scale mobile cluster. To cope with the limited processing power and memory space, we first present an effective 3D scene representation scheme suitable for mobile GPU rendering. Then, to avoid performance impairment caused by the high latency and low bandwidth of mobile networks, we propose using a static load balancing strategy, which we found to be more appropriate for the vulnerable mobile clustering environment than a dynamic strategy. Our mobile distributed rendering system achieved a few frames per second when ray tracing 1024 × 1024 images, using only 16 low-end smartphones, for large 3D scenes, some with more than 10 million triangles. Through a conceptual demonstration, we also show that the presented rendering scheme can be effectively explored for augmenting real scene images, captured or perceived by augmented and mixed reality devices, with high quality ray-traced images.
