An Energy Saving Routing Scheme for WSN based Crop Field Monitoring System

In this era of wireless communication, Wireless Sensor network (WSN) has drawn considerable attention to the researchers. This paper proposes a new scheme of energy efficient routing technique in WSN for surveillance of agricultural field from a distance place. In this scheme, a crop field is equipped with different types of sensor nodes with limited power source, placed randomly for sensing various properties of soil like salinity, moisture, temperature and PH. Here in addition to grid shaped clustering, the tolerance percentage of sensed data of above mentioned parameters have been introduced to offer an energy efficient clustering and percentage tolerance based algorithm. The effectiveness of the proposed scheme has been evaluated in terms of the number of alive nodes as well as the number of transmitted and received data packets. To establish the supremacy of the proposed techniques over the others, the results have been compared with those of Low-Energy Adaptive Clustering Hierarchy (LEACH), Divide and Rule (DR), Grid Based clustering.
