Abstract

At present due to limitation and computing power and energy resources of sensor node the data is aggregated by extremely simple algorithm such as averaging data from multiple sensors is aggregated at aggregation node which is done at base station only the aggregate values. Such algorithm is very vulnerable to false and more important malicious attack since WSNR usually un attend without tamper resistance network they are highly susceptible to such attacks. This ca nnot be remedied by cryptographic methods, because the attackers generally gain complete access to information stored in the compromised nodes. For that reason data aggregation at the aggregator node has to be accompanied by an assessment of trustworthines s of data from individual sensor nodes. Thus better and more sophisticated algorithm are needed for data aggregation in further WSNR Iterative filtering algorithm are attractive option for WSN because they solve both problem data aggregates data trustwort hiness assessment using a single iterative procedure such algorithm simultaneously aggregated data from multiple sources.
