Recently, Wireless Sensor Networks (WSNs) have attracted lot of attention due to their pervasive nature and deployment in many real world applications. Sensor nodes are scattered in the environment to sense and send the specified data back to the desired users. To achieve this goal, we need an efficient and scalable routing protocol that can select the most optimal routes between the sensor nodes and users who are normally far away. Since sensor nodes need to be embedded in the environment they tend to be very small with low processing and memory and have small battery sizes. To prolong the lifetime of the network and wireless sensor nodes, an important requirement of wireless sensor routing protocols is their energy-efficiency. We review recent energy-efficient wireless sensor routing protocols, which have been proposed recently in the literature and evaluate them using a comprehensive taxonomy.
