Dynamic scheduling technique (dst) to improve selective throughput in wireless sensor network

摘要

A wireless sensor network (WSN) consists of sensor nodes connected wirelessly in the network. Sensors are tiny, low-powered physical devices with capability to sense, monitor and communicate in the network. These deployed nodes are responsible for sending the data, to the destination node which is the sink node. The gathered information may contain data regarding the wildlife in forests, pressure, oceanic activities and many more depending upon the region where they are deployed. Many a times a sensor senses an event, e.g. forest fire. Hence this should be conveyed to the base station at highest priority, than other less vital data packets transferred in the network. This can be achieved with Dynamic Scheduling Technique (DST). By using DST the selective throughput can be increased as, high priority packets are given more preference over medium and low priority packets. The dynamic approach of DST also increases the overall throughput, as the empty slots which were present in the buffer can be occupied by other priority packets depending upon the availability different priority packets. Following invention is described in detail with the help of Figure 1 of sheet 1 showing dynamic scheduling technique.
