Wireless sensor network contains sensor nodes which are spread to sense the ecological surroundings, collect data and transfer it to a base station for processing. Energy conservation in the Wireless Sensor Network (WSN) is an important task due to their inadequate battery power. The related works till now have already been done to resolve the issue keeping in mind the constraints of WSNs. From the survey, it has been revealed that the prevailing methods has used queuing model which might be able to restrict the performance of the congestion control algorithm. The behavior of the queue has been neglected for coverage fidelity, queuing thresholds, number of queues, blocking probabilities etc.
