Wireless Sensor Networks (WSN) being the major thrust research focus area to address the related issues of quality-of-service (QoS) such as energy consumption, life time of network and packet overhead. Packet overhead leads to consume more energy that tends to performance degradation in QoS. This paper aims to provide the extracts of energy efficiency of wireless sensor networks. For suggesting improved performance on WSN, this survey consider articles that describes the effectiveness of forming clusters and cluster heads for forwarding the packets, portray the optimal load sharing algorithm using hopping of Base Station to enhance the life time of network, illustrate the significance of routing protocols to know the trustiest nodes, bring-in the sleep/wake mechanism for preserving the optimum energy and demonstrates with the discussion on cross-layer optimization to optimize the node usage. Finally this paper ends with the findings.
