Hybrid Approach for Data Aggregation in WSN with Advance Security Protocol in NS2 Software

Abstract

Energy efficiency is a crucial resource constrained WSN. Diverse techniques for example duty cycling, optimization energy scheduling and data aggregation are applied so that energy can be used minimum. In this research paper there are two main domains on which work carried out successfully. First one is data aggregation but data aggregation in our work is of two levels. Another domain was security because as we know in MANET security is not up to the mark that is why unauthorized person can access the data by deploying malicious note in our existing network. A robust analytical development of the proposed protocol is presented by using concept of two level data aggregation. Quiet satisfactory performance of the proposed algorithm is depicted. Data aggregation is attained by iteratively applying the proposed compression method at the cluster heads and on the other hand data aggregation scheme in the presence of a Multi-interface Multi-Channel Routing Protocol is tested. One important thing is that in a cluster. A node can be cluster head only single time after that new node will be cluster head. MMCR uses a metric defined by various parameters like throughput, end-to-end delay and energy utilization to select Multi-Point Relay nodes to forward data packets in each channel but keeping in mind that loss of packet or information must be reduced. Finally we can say that proposed algorithm is far better than existed protocol. Besides that RSA security algorithm for encryption and decryption also applied so that unauthorized person cannot access the information. There are various security algorithm available but selection must be appropriate as per desired application.
