Blockchain based packet delivery mechanism for WSN

Abstract

The latest trend in the research filed implies the importance of data security in wireless sensor networks. There are various approaches identified for securing the data by using trust wide security such as cryptographic systems and routing protocols. However, these approaches are very critical to identify the optimal path in the network and attacks by unauthorized node cannot be prevented. In this paper, a new algorithm for combining the AODV (Ad Hoc On-Demand Distance Vector) routing protocol and particle swarm optimization (PSO) is implemented to produce trustable routing in every location through block chain. The possible routing procedure will enhance the routing nodes to acquire routing information among all the nodes but will never allow the node to capture the information. The routing protocol on the blockchain is used to utilize the path efficiently without deviation caused by other anchor nodes. It also identifies the congestion in the entire path of the particular network and avoids tampering of information between the nodes. The blockchain enabled with PSO algorithm and AODV routing protocol provides the simulation results about the efficient packet delivery system. The Security has been performed in every node used to identify the best route for producing the efficient throughput and quality of services.
