Routing Algorithm based on Energy and Hop Number for Linear Distributed WSN

Monitoring nodes are usually linear distributed along river and canal in irrigation area, which constructs linear distributed WSN. Aiming at linear distributed WSN, Flooding routing protocol based on energy and hop number (BEH-Flooding) is proposed. This protocol realizes efficient and stable wireless data transmission for irrigation area. According to the principle of same hop number, nodes are divided into multiple levels. In each level, two routing nodes are selected based on the principle of optimal residual energy. In the transmission stage, data packets are only transferred between routing nodes of upper level and routing nodes of lower level. By this, the protocol not only has the robustness of Flooding protocol, but also reduces extra data transmission. The simulation results validate the effectiveness of the proposed routing protocol. This method provides an approach to data acquisition for monitoring system in irrigation area.
