A wireless sensor network is a network of hundreds of sensor nodes, which are generally positioned in a close neioghborhood to provide wireless sensing capabilities to the establishment. The nodes consist of fixed resources of their operation thus effective utilization of the battery is an important factor. This requires optimum routing methods. A review of Wireless Sensor Networks routing protocols was provided in this research paper. Energy-efficient routing methods were used to keep long-term service life of the sensors and the network in turn. This is this paper's primary study goal.
