Threshold Sensitive Region-Based Hybrid Routing protocol for precision agriculture

Today's precision agriculture needs advance methods and technology to reduce cost and improve productivity. This paper explores the potential use of wireless sensor network in precision agriculture. An energy efficient network layer routing protocol is required to maximize the lifetime of sensor network. The proposed Threshold Sensitive Region-Based Hybrid Routing (TS-RBHR) protocol uses region-based static clustering approach to provide efficient coverage of agricultural area. The fuzzy based hybrid routing approach is used for transmitting sensed data to base station which minimizes the energy consumption of nodes. Sensor nodes continuously sense temperature and soil moisture content of agricultural field and if sensed value exceeds the desired threshold, a data packet is sent to the base station which reduces the continuous transmission rate. The experimental results show that proposed protocol has a significant increase in network lifetime due to reduction in frequent data transmission.
