Wireless Sensor Network is a relatively distributed community of small and light-weight sensing nodes which are deployed in a huge wide variety at a couple of places. These networks are useful in monitoring the device or environment. These sensor nodes plays sensing, processing and then communicating. Now a day’s those networks are carried out in diverse fields like army, defence, wooded area fireplace, scientific, disaster management etc. In this paper it has been mentioned about sensor network architecture and major factors affecting the wireless sensor networks. Routing is a chief undertaking faced by way of wireless sensor networks due to the dynamic nature of WSNs. Since power efficient routing protocols are of fundamental challenge in the field of wireless sensor network. Therefore in further sections of this paper it has offered a quick evaluation of different strength green routing protocols proposed for wireless sensor networks.
