| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The coverage problem is one of major issues to prolong the lifetime of a wireless sensor network while guaranteeing that the target region and objects are monitored by the sufficient number of active sensor nodes. There have been many proposals on the coverage problem. However, most of them require sensor nodes to exchange information about the location, sensing area, and sensing state with neighbor nodes in order to determine whether to monitor around or sleep. In this paper, we propose a novel coverage control mechanism where each sensor node relies only on the abstract information about the degree of coverage of the whole target region. To enable autonomous decision of sensor nodes, we adopt a nonlinear mathematical model called the attractor selection model for flexible and adaptive behavior of biological systems to dynamically changing environment. Through simulation experiments, it is shown that the proposal can accomplish the same level of coverage as the random method with fewer active nodes by 20 %. | |
