Wireless sensor network provides a way of information sensing, processing, communicating and transfer of information. The sensor nodes depend on their battery to carry out these operations. Once the node runs out of its battery it will be discarded. Hence, energy consumption in WSN plays a vital role in choosing a routing protocol. In this paper, the authors analyze types of routing protocols in WSN i.e., flat routing and hierarchical routing. A comparison is carried out in terms of throughput, end-to-end delay and the node energy utilization.
