EEBASS: Energy-Efficient Balanced Storage Scheme for Sensor Networks

Data-centric storage is an effective and important technique in sensor networks, however, most data-centric storage schemes may not be energy efficient and load balanced due to non-uniform event and query distributions. This paper proposes EEBASS, it utilizes an approximation algorithm to solve the optimal storage placement problem according to the variance of event and query distributions, aiming to minimize the total energy consumption for data-centric storage scheme. And it further leverages a ring based replication structure to achieve the load balance goal. Simulation results show that EEBASS is more energy efficient and balanced than traditional data-centric storage mechanisms in sensor network.
