In this study, we use tracking models to predict a moving object's path in a wireless grid sensor network. The system determines the sleep and awake schedules by using tracking to efficiently conserve energy. At first, the network is divided into several grids by using grid computing. Neighboring grids can communicate with one another and construct an(More)
To solve the location issue, in this paper, we proposed a Received Signal Strength for Directional Antenna (RSS-DA) scheme, it uses the mobile anchor nodes that already know the coordinates to join the Received Signal Strength (RSS) measurement in the data transmission. The number of beacons conforms to the terminated threshold in the sensor nodes, the(More)
