A wireless sensor network is a collection of nodes organized into a cooperative network. The nodes communicate wirelessly and often self-organize after being deployed in an ad hoc fashion. Currently, wireless sensor networks are beginning to be deployed at an accelerated pace. This new technology is exciting with unlimited potential for numerous application areas including environmental, medical, military, transportation, entertainment, crisis management, homeland defense, and smart spaces. In particular, their application to healthcare areas received much attention recently. The design and development of wearable biomedical sensor systems for health monitoring has drawn particular attention from both academia and industry. Therefore, focus has been given to the routing protocols for maximize the life time of wireless sensor network. In this paper we present a survey on power efficient hierarchical routing protocols in Wireless Sensor Network. Firstly, the routing techniques has been discussed for WSN. The drawbacks and comparative study of routing protocols has been discussed. Finally, the existing research issues in wireless sensor network is provided.
