Abstract

Wireless Sensor Network (WSN) challenges in the transmission of data are its network traffic and network security. Another issue in sensor network is Compromised node and Denial -of -service attack (DOS).Multipath Routing Algorithms are vulnerable to these attacks. A Key Management scheme is used with this routing algorithm to generate randomized multipath routes for secure transmission of data to the sink. We adopt Shamir's algorithm for efficient key management which is scalable, highly secure and decreases communication overhead. Randomized Route Generation changes the routes taken by the shares from time to time thereby increasing the probability of randomness of paths to be selected for transferring data in a much secured manner. To bypass the black hole, opponent has to selectively compromise nodes or block the shares containing the message which traverse randomly which is very difficult.
