Abstract:-Routing effectively and efficiently is an important task for all networks, especially for wireless networks

-Routing effectively and efficiently is an important task for all networks, especially for wireless networks. WSN based application make the use of WSN (wireless sensor network) generated data which has force to the design of WSN architectures and systems. Numerous Quality of Service requirements by discrete applications focus on the use of appropriate routing metrics to decide the amend data path [12]. The Network performance is directly linked to the routing protocol in place and the metric it uses to optimize specific network performance aspects [2]. Wide literature study on routing metric pageant that WSNs are still not affective due to lack of affective routing and shortage of power backups. In this paper we tried to reinforce the routing metric by testing one of the combination approaches. By practicing in this way the effectiveness of the routing protocol also get increased. Now, the new enhanced combined routing metric giving better result than existing routing metric.
