A Review of Energy Efficient Routing Protocols in Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are collection of randomly distributed minute devices mainly named as nodes which interact with each other and base station to transmit the required information to the controller via Internet. These networks sense or track the phenomenon, occurring at an unattended place. The major constraint of the WSN is limited life of sensor nodes due to loss of energy. Several routing protocols are developed to transfer the information or data among these nodes in an efficient way and to enlarge the lifetime of nodes. A thorough review of different categories of routing protocols has been discussed in the presented paper.
