Among critical issues in Wireless Sensor Network (WSN) some impose more limitations over the design and implementation of an optimum WSN like channel capacity, resiliency, energy saving due to the limited availability of energy in wireless nodes, data privacy and confidentiality. A widely employed energy-saving technique is to utilize data aggregation. Data aggregation can reduce the number of transmitted packets within the network and prolongs the battery life. In return, data redundancy is required for secured transmission and privacy in interference limited and noisy environment. In this paper, a highly secured data aggregation method for WSN is proposed which ensures that information of all live nodes inside the network is accessible inside the sink node with the minimum redundancy. In our scheme, data of all live nodes stored in the sink are accessible inside the sink even if the wireless channel is polluted with noise and interference. Numerical results demonstrate better results in comparison with other presented algorithms.
