Comparison on Hierarchical Routing Protocols in WSN

Nowadays, wireless sensor networks are an emerging technology which plays a vital role in every field. Wireless sensor networks, as the spatially distributed networks consisted of a number of relatively simple, low-cost, low-power components interconnected mutually, provide quite wide application for different areas. Sensor networks works with the help of nodes which are battery driven. Since it loses its energy during transmission, the lifetime of the network is reduced. The main issue in the wireless sensor network is to enhance the network lifetime. Many researches are still going on to improve the time span of the sensor nodes. In this paper, a survey on different energy based routing protocols has been done.
