Energy Efficient Routing Scheme for Enhancing Lifetime in Wireless Sensor Networks

Sensors are most important components used in lots of electronic devices where human life is associated. A wireless sensor network has many applications where the most important information is to be transferred to the base station in energy efficient manner through multi-hop communication, Due to the tiny size of senor node there is a limited capacity of power and network do not work a long time, further it is very difficult to replace the battery in some hostile area, Therefore an energy consumption scheme or algorithm is needed to extend the network lifetime. The base station is located at the corner of network. In this paper an Improved-Distributed Energy Efficient Clustering (I-DEEC) scheme is proposed and evaluated. The scheme is simulated on MATLAB considering different size of network 100-500 nodes to check the efficiency on different parameters and compared with obtainable protocols DEEC and EESAA. These routing protocols are considered due to functionality of energy efficiency. The developed scheme extends the lifetime of network by selecting the finest shortest path to transmit the data packets. The optimal path can be selected according to the maximum remaining energy at the node for next hop with quality link and minimum number of hops. The Simulation results show that the I-DEEC scheme enhances the lifetime of network 8%-12%, reduces the power utilization 13%-19%, minimizes the delay for transmitting the packets and increases the packet delivery ratio.
