Design and implementation of in-network multilevel data aggregation in wireless sensor networks

Abstract

In Wireless Sensor Network (WSN), the role of data computation and communication among the sensor nodes are noteworthy. At the instant of covering a huge area, lot of issues faced like lifetime of nodes, energy consumption, redundancy of data, faster data communication etc. To prevail over these issues, the multilevel data aggregation within the network is designed and implemented with the help of PIC and ARM microcontrollers. The multilevel aggregation superintends the redundancy of data effectually in contrast to single or two level data aggregation. It is appended to intensify the lifetime of the network by decreasing the amount of data transmission to Base Station (BS) and aggregating the similar as well as near similar data packets in an effective methodology. By exploiting this in a wide agriculture fields, diverse parameters can be easily monitored such as temperature, moisture, soil and water levels etc. Using the BS data, the required actions can be performed in the field.
