Associate Professor Leow Wee Kheng received the Andrew P Sage Best Transactions Paper Award in a ceremony in October 2007.
The award recognizes the best paper published annually (2006) in IEEE Transactions on Systems, Man and Cybernetics (Part A, Part B, and Part C).
In 2006, more than 300 papers were considered.
Associate Professor Leow co-authored the paper with his then student Low Kian Hsiang, and Associate Professor Marcelo Ang from the Faculty of Engineering.
Here are some information on the paper:
Kian Hsiang Low, Wee Kheng Leow, Marcelo H. Ang, "Autonomic mobile sensor network with self-coordinated task allocation and execution", IEEE Trans Systems, Man, & Cybernetics, Part C, 36(3):315-327, MAY 2006
This paper describes a distributed layered architecture for resource-constrained multi-robot cooperation, which is utilised in autonomic mobile sensor network coverage. In the upper layer, a dynamic task allocation scheme self-organises the robot coalitions to track efficiently across regions. It uses concepts of ant behaviour to self-regulate the regional distributions of robots in proportion to that of the moving targets to be tracked in a non-stationary environment. As a result, the adverse effects of task interference between robots are minimised and network coverage is improved. In the lower task execution layer, the robots use self-organising neural networks to coordinate their target tracking within a region. Both layers employ self-organisation techniques, which exhibit autonomic properties such as self-configuring, self-optimising, self-healing, and self-protecting. Quantitative comparisons with other tracking strategies such as static sensor placements, potential fields, and auction-based negotiation show that our layered approach can provide better coverage, greater robustness to sensor failures, and greater flexibility to respond to environmental changes.
