HOP TO HOP CONFIDENTIALITY WITH DATA ENCODING IN WIRELESS SENSOR NETWORK

ABSTRACT In wireless sensor network messages are transferred between multiple source and destination pairs cooperatively such way that multi hop packet transmission is used. These data packets are transferred from intermediate node to sink node by forwarding packet to destination nodes. Where every node over hear transmission near neighbour node. To avoid this we propose novel approach with efficient routing protocol i.e. shortest path routing and distributed node routing algorithm. Proposed work also focuses on Automatic Repeat Request and Deterministic Network coding. We propagate this work by end to end message encoding mechanism. To enhance node security pairwise key generation is used, in which paired communicating node is assigned with pair key to make secure communication. End to end. We analyze both single and multiple nodes and compare simple ARQ and deterministic network coding as methods of transmission.
