Self Organizing Secure WSN for IOT Implementation

Surabhi Gehi, Roshan Jain

As wireless sensor networks are gaining widespread acceptance &popularity the need for making the secure & easily deployable is emerging as major challenge. This work is aimed at development of aself organizing wireless sensor network which employs tree hierarchy & provide high level of security using the most advanced cryptography & key sharing technique MATLAB is employed to demonstrate. Automatic node initialization tree based node organization employment of wireless node machine address in private key generation & use of natural randomizers to enhance security. Also communication between nodes that node to node or node to base /master over TCP/IP is demonstrated. A master node or base node which is the tree root handless all node initialization addition & deletion in conjunction with random key generation server. Also the base node facilitated generation of separate private keys for every node under it. Thus a highly secure hierarchical WSN is presented for IOT implementation.
