Since the peoples have limited energy and computing capacity, To aggregate data from many sensor nodes using basic techniques such as averaging. WSNs are often unattended, making them very susceptible to node compromise attempts. As a result, determining the reliability of data and the reputation of sensor nodes is critical for WSN. Iterative Filtering methods were discovered to be very useful for this purpose. These algorithms aggregate data and offer trustworthiness evaluation to nodes in the form of weight factors. These algorithms aggregate data from many sources at the same time and give a trust estimate of these sources, often in the form of matching weight factors applied to data supplied by each source. In this article, examined various safe data aggregation methods and presented a novel complex collision attack with implications for wireless sensor networks.
