A Review On Routing in Wireless Sensor Networks

The concept of wireless sensor networks (WSN) have recently evolved in years and have seen continuous growth in diverse areas, leading to provision for new opportunities in networking and services. A WSN consists of an array of sensor networks interconnected by a wireless communication network. The applications of WSN are endless and have gained focus due to the recent advancement in wireless communications and electronics. Routing can be of many types as location based or hierarchical. Various hierarchical routing protocols are analyzed in this paper.
