摘要
Nowadays, Wireless Sensor Networks (WSNs) play a vital role in agricultural field for improving growth rate and to reduce the resource utilization like water, manpower, etc. WSNs are used to monitor the environmental conditions of the agricultural field to achieve the automatic irrigation for the different plants in large areas of agricultural land. WSNs include a number of inexpensive energy constrained in sensor nodes, which collects the environmental data from large scale agricultural land and transmit the data to the base station. The network lifetime and Quality of Service (QoS) should be improved in agricultural WSN for better performance. For achieving this, the node power consumption should be reduced. By introducing clustering technique for the nodes in the agricultural field, it is observed from the simulations, that the energy consumption is reduced to a considerable amount thereby increasing network lifetime. The cluster formation is done based on neighbor node and residual energy, which overcomes the drawbacks such as network early dead, excess energy consumption, poor efficiency in packet delivery, link stability problem, etc., The simulation results shows that the proposed algorithm gives better performance in terms of Packet Delivery Ratio (PDR), throughput, energy consumption and network lifetime. Hence, it is understood that it is more suitable for large scale WSN installed in agricultural lands.
