Spider Web Based Dynamic Key for Secured Transmission and Data Aware Blockchain Encryption for Internet of Things

In the developed field of information and communication systems, the utilization of wireless sensor networks (WSN) is greatly increasing. In WSN applications, data gathering with limited energy consumption and good security is essentially needed nowadays. The network is energy limited as the sensor nodes are operated using battery power. The nodes in WSN are vulnerable to several attacks and the proposed data transmission scheme should provide network security. The security is a main concern in data aggregation. In this work, a secured data aggregation scheme with compression technique and blockchain encryption added routing is presented. The existing methods on secured data aggregation give protection against attacks; still they suffer from issues such as energy, memory size and transmission costs. The devices in the network transmit data to the base station/server in the network through gateways. The data transmitted by the device is added with a hash key generated using spider web based dynamic key (SWDK) generation process. Then, compression based data aggregation is utilized to reduce the data size and sequentially the transmission cost. The security added compressed data is transmitted using block chain encryption routing. The simulation results prove that the proposed work gives reduced transmission cost and energy consumption comparing with the existing works. The network throughput increases due to the sharing security keys, as well as network latency and packet dropping are reduced in the proposed work.
