An Overview of the Routing Techniques Employed in Wireless Sensor Network

Wireless Sensor Networks have found their reach in various domains that includes defense, medicine and environmental monitoring. The network is formed by a vast collection of sensor nodes which are stationed separately from one another. The information gauged by the sensors needs to be conveyed to the sink node so as to take the obligatory steps. Routing of the compiled information from the source node to any specific sink node, attaining minimal power consumption and minimizing the presence of congestion are some of the issues encountered in wireless sensor networks. This paper throws light upon a few of the routing techniques engaged in the network for the transmitting the sensed information.
