Fig. 2From: An efficient data collection path planning scheme for wireless sensor networks with mobile sinksCommunication ranges of sensors in a sensing area with obstacles (1000 m × 1000 m). The sensing area is 1000 m × 1000 m, the number of sensor nodes is equal to 10, and the number of obstacles is equal to 5. In this figure, a circle represents the communication range of a sensor node, and a square represents an obstacleBack to article page
