| Research Abstract |
Wireless sensor networks have attracted a great deal of attention. The performance of wireless sensor networks is greatly influenced by the initial physical placement of the sensor nodes. In this research, we proposed a novel deployment method for sensor nodes, when a large number of nodes is distributed from the air in a monitoring region that is inaccessible from the ground. In our deployment method, each sensor node is equipped with a parachute and a device to switch between its two falling behaviors in the air. After being dropped from midair, sensor nodes stochastically coordinate their falling behavior in order to distribute themselves uniformly in the monitoring region. Through simulation evaluations, we confirmed that our proposal can achieve a high uniformity in the placement of the nodes.
