A wireless network is a bunch of variety of sensor nodes and forwarding nodes which are randomly placed in remote area to observe various changes in applications like soil, forest, sea, wind, temperature, humidity etc. WSN have many applications in tracking of objects, habitat monitoring, battlefield, healthcare among others. The performance of a sensor network depends on different QOS parameters such as reliability, throughput, congestion and energy. The energy and reliability are two important measures in WSN. There is always tradeoff between Reliability and energy. The power efficiency and desired reliability is achieved dynamically by varying transmission range .Power Aware Controlled Reliability Protocol also uses strategy to improve average packet delivery ratio, average throughput, reliability during the data transmission, and reduce average energy consumption. This invention not only achieves desired reliability but also increases network life time. This protocol is deployed on each node in the network. Following invention is described in detail with the help of figure 1 of sheet 1 showing flow chart of Power Aware Controlled Reliability Protocol |
