Sensor network has emerged as a promising tool for monitoring the physical world, utilizing self organizing networks of battery powered wireless sensors that can sense. Sensor network nodes are limited with respect to energy supply, restricted computational capacity and communication bandwidth. To enhance the lifetime of the sensor nodes, designing efficient routing algorithm is important. As sensor networks are primarily designed for monitoring and reporting events, i.e. they are application dependent. The authors' survey is to present a comprehensive review of routing algorithm. In this paper, they give a survey of routing protocols for wireless sensor network and their applications.
