Enhancement of security in WSN using ETDES and BBDT technique

A wireless Sensor Network (WSN) consists of Sensor nodes and these nodes are meant for sensing and communicating information through a wireless network. These nodes have limited energy and storage capacity while communicating with each other. The data should securely transmitted from source to sink nodes. If data is not securely transmitted, then security is needed for those sensor nodes. So security is the major challenging issues because it can be used for both controlling and monitoring, while sending the data from one network to another network through a routing path, the attacker may capture the data, attack the data, or attacks on the routing table. So, high – level Security is required for the sensor nodes due to interrupted and insecure communication in a wireless network. In this proposed work, Triple-DES is enhanced with the help of AES algorithm (ETDES) and implementation of blockchain (BBDT) in a wireless network. So data will be divided into number of blocks through different routing paths which secure data communication in between sensor nodes to reach to the destination. Blockchain based data transmission (BBDT) used for transmitting the data from sensor to base station
