Minimization of energy consumption is one of the most vital objective for Wireless Sensor Network (WSN) based applications. The rate of the node’s energy consumption is based on the sampling rate of the sensors in wireless sensor networks (WSNs), since most of the energy is used in sampling and transmission. To save the energy in WSNs and thus prolong the network lifetime, this paper presents a novel approach based on Event-Driven Algorithm (EDA) with code-driven strategy. In this algorithm, energy efficient wireless sensor network has been developed and code driven protocol for data forwarding which minimize the transmission power of sensor node has been designed. The proposed algorithm has shown 68% increase of network lifetime in Event-Driven Algorithm (EDA) and 79% increase in CodeDriven Algorithm (CDA) when compared with a continuous monitoring algorithm. The performance of the proposed protocol is analyzed experimentally using Crossbow IRIS motes under TINY OS environment and results are discussed.
