In this paper, we focus on protecting the sink's location when global-eavesdropper exists in wireless sensor networks. The adversary is assumed to have the ability to monitor all the communications of the network, which means that she can follow a route of a message and find the location of sink node easily. In this case, we introduce several fake sinks to confuse the adversary such that she has to...
This paper presents a control and coordination algorithm for a group of autonomous agents to find the optimal path in a partially known environment. The novel control law utilizes the simulated annealing algorithm to search for the optimal path avoiding obstacles and threats or being trapped into the local values, but converging to the global optimal path with probability 1. We also show the multi-agent...
Object matching is an important issue for machine vision, object recognition and image analysis. A Hausdorff distance is one of commonly used measures for object matching because it is simple and insensitive to changes of image characteristics. But the conventional Hausdorff distances require high computational complexity and are not suited to the practical applications. In this work, we propose a...
