Using data aggregation to prolong the lifetime of wide-area wireless sensor networks

The present paper presents a solution for prolonging the battery life for motes within a wide-area wireless sensor network (WSN). In this particulars networks, the distances between motes and base stations are over the motepsilas communication range, and motes located between sinks and base station are commonly used both as regular motes and repeaters. This diminishes their energetic autonomy and increases lifecycle maintenance costs. The power constraint has a great impact on the functioning of wireless sensor networks; the battery life makes the data communication very high-priced and restricts the amount of transferred data. A study case is performed considering a wide-area WSN functioning in different modes, with no data aggregation and then using in-network data aggregation.
