A Multi agent system (MAS) is used to manage these sensors for collecting data from them and storing
them in a database. The proposed MAS consists of four agents namely Admin agent, Control agent,
Query agent and Data agent which performs data reduction using Epsilon approximation. The use of Data
agent in the proposed scheme reduces data traffic and the requirement of secondary storage space. The
proposed agent based system has been implemented using Java language in JADE environment and the
results are validated. The reduction algorithm used here gives a reduction ration of about 80 percent. The
performance of the reduced set of values is close to the original set and the query agent uses these reduced
values to answer the queries later.
