Abstract: Recent year’s extensive research has been conducted on routing protocols for Wireless Sensor Network because of its numerous applications. A wireless sensor network is a collection of sensor nodes prearranged into a collective network to monitor the remote and physical environment. These sensors nodes are capable with limited processing and computing resources. The design of these routing protocols is to minimize the energy consumption in the network during transmission of information. During radio transmission and reception these sensor nodes consumes lot of power, hence forth to maintain uninterrupted transmission energy efficiency should be analysed and it is considered as one of the critical parameter in wireless sensor network is the inherent limited battery power within the sensor nodes. In this paper, the focus is mainly driven towards the review of energy efficient routing protocol and its design issues. Different routing protocols pros and cons were analysed. Some standard cluster–based available routing protocols were compared with respect to their clustering attributes for wireless sensor network.
