Advances in wireless sensor network (WSN) technology has provided the availability of small
and low-costsensor nodes with capability of sensing various types of physical and environmental
conditions, data processing, and wireless communication. Variety of sensing capabilities results
in profusion of application areas. However, the characteristics of wireless sensor networks
require more effective methods for data forwarding and processing. In WSN, the sensor nodes
have a limited transmission range, and their processing and storage capabilities , as well as their
energy resources, are also limited. Routing protocols for wireless sensor networks are
responsible for maintaining the routes in the network and have to ensure reliable multi-hop
communication under these conditions. In this paper, we give a survey of routing protocols for
Wireless Sensor Network and compare their strengths and limitations
