EERS: Energy-Efficient Renewable Scheme for Wireless Sensor Networks

We analyze unequal energy utilization in a broad class of many-to-one sensor networks in this article. All sensor nodes in a many-to-one sensor network generate constant bit rate (CBR) data and send it to a single sink through multi-hop transmissions. This sensor network has a wide range of possible applications, including environmental monitoring and data collection. Based on the observation that sensor nodes near the sink would relay more traffic than other nodes in the outer sub-regions, our study confirms that nodes in the inner rings have much higher energy consumption rates (ECR) and thus have much shorter predicted lifetimes. We suggest an energy-efficient renewable scheme (EERS) to save energy based on the overall energy usage review. We argue that the basic advantages provided by developments in WSN technology can be put to good use for local distributed intelligence and control. The collected experimental data is analyzed to gain insight into the characteristics of the proposed solution.
