Performance Analysis of Energy Efficient Cluster Based Heterogeneous Wireless Sensor Network against Malicious Attack

摘要

In a distributed Wireless communication technology, sensor networks have been proposed for use in many applications such as environmental monitoring and surveillance. Due to the different computing power, sensing range and different ability, the deployment and topology in Heterogeneous WSN(HWSN) is complex compared to Homogeneous WSN. Clusters are formed in Heterogeneous Wireless Sensor Network and Cluster Head (CH) is selected based on the Initial Energy and Residual Energy with Low Draining Rate (RELDR). Data from the cluster members are sensed, aggregated and summarized by cluster head, processed between the clusters. A node in a network called Cluster Authority (CA) works as a supervising node that has remove list which collects the attacker information. A concept using Multiple Inputs and Multiple Outputs (MIMO) is implemented in the work which reduces the noise and improves the network performance. The algorithm detects the Blackhole nodes and removes from the network which is listed in the remove list of CA. The network is reconstructed using the legitimate nodes and cluster head selection is based on the Residual energy in the next rounds. Experimental results will be analyzed for the parameters Packet Delivery Ratio, Throughput, End to End Delay, Overhead and Energy. Performance analysis is done with the existing system using Single Input and Single Output(SISO).
