Abstract |
Typical wireless sensor networks (WSNs) comprise a lot of small, lightweight sensor nodes to cover an area to collect data. These sensor nodes are work on the power source Therefore the battery energy of sensor nodes has to be very carefully and cleverly utilized. Additionally, it is also very important to balance the energy consumption of the nodes so that the network stay connected and functional for a long time. Wireless communications have become very pervasive over the time period. WSNs have wide range of application such as traffic analysis, environmental monitoring, industrial process monitoring, and tactical simulations. In WSN, the data packets are transmitted from source node to destination through several intermediate nodes which forward data packets towards the next one hop neighbor. However, each node participates simultaneously in several data transmissions. Each technique of packet scheduling is used for improving the efficiency of the network based on certain performance metrics and scheduling factor and every technique having some limitations. |
