Wireless Sensor Network nodes are battery powered nodes. Main focus of this article is to reduce the energy wastage and increase the lifetime of Wireless Sensor network by balancing the energy level of all nodes in network. Sensor nodes are small, cheap; resource limited devices and sensing the environment and communicating with each other. It consumes energy to transmit, to forward and to receive the data over network. Network lifetime is depends on energy level of nodes, depends on processing power of node, memory and transmitter power. Transmitting speed and receiving speed are differing from node to node. Saving more energy of sensor node by using energy efficient algorithms, the network lifetime will get increased. Survey is based on different techniques, which are to avoid the energy wastage of nodes in network and its success.

Keywords: WSN, MHHC, routing, sensor, energy saving.
