Abstract
Wireless Sensor Networks needs energy e cient routing protocols for increasing the network lifetime. e en- ergy consumption of sensor nodes can be decreased by reducing the transmission radius range. In this proposed work an Energy E cient Routing Protocol (EERP) is developed for wireless sensor network by adjusting the node transmission radius and conserves the node energy. EERP follows on demand routing method for packet forwarding from source to destination. When the node’s energy reaches certain threshold then node reduces its transmission radius again in order to achieve less energy consumption under the circumstance. e trans- mission range distribution optimizations for networks are developed in order to obtain the maximum lifetime. Analysis of the solution shows that network lifetime improvement can be obtained through optimization comes at the expense of energy-ine ciency and a wasting of system resources. e simulation results shows that EERP protocol outperforms the existing routing protocols in terms of network lifetime, energy consumption and has a balanced network load and routing tra c.
