Wireless Sensor Networks and Its Routing Protocols: A Comparative Study

Wireless sensor networks with hundreds to thousands of sensor nodes can collect information from an un attendant environment and transmit the collected information to a specific user depending on user end application. These sensor nodes have some constraints due to limited energy, storage capacity and computing power. Data sre routed from one node to another using different routing protocols. There are a number of routing protocols for wireless sensor network. In this review article, we discuss the architecture of the wireless sensor network. Further, we categorize the routing protocols according to some factors and summarize on their mode of operation. At the end, we put up a comparative study on these protocols.
