A new direction-based routing protocol in WSNs

Abstract

It is important to extend the network lifetime by using the limited energy of the sensor node efficiently in Wireless Sensor Networks (WSNs). LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol is very well-known as one of most often used cluster based hierarchical routing protocols for WSNs, however, it wastes unnecessary data transmission energy for reverse direction when the sensor node exists between the cluster head and the base station. In this paper, we have proposed D-LEACH (Direction-based LEACH) protocol to reduce such energy wastes by considering the data transmission direction of sensor nodes. Our experiment has shown D-LEACH extends the network life by increasing the efficiency of the data transmission energy usage.
