Improved Inter-Cluster Data Aggregation HEER Protocol?

Wireless Sensor network consist of independent large number of sensors and energy efficiency is one of the most important concerns in Wireless Sensor Network. To resolve issues of energy consumption, reliability and data aggregation several routing algorithms have been proposed earlier. We can prolong network lifetime and stability period by reducing energy consumption. The proposed protocol focuses on some defects of existing HEER protocol and improves network lifetime. In the proposed protocol, improved inter cluster data aggregation is introduced to perform better and provide uniform energy consumption. Finally, simulation result shows that our proposed protocol has better network lifetime and stability period than that of existing HEER.
