Cluster Based Wireless Sensor Network: Security Using SHA1 and Authentication using Election Algorithm

Abstract The proposed system is on Wireless sensor network and clustering technique has been applied for better communication with a cluster leader election among nodes. The cluster head helps is better communication this is been done with election algorithm .even though security has been main problem for this SHA1 algorithm, an industry standard algorithm is been implemented. SHA1 helps is sending Encrypted message and files over network providing security mechanism. SHA1 is 128 bit Encryption algorithm and used along with MD5 and Digest for providing security to web application. Proposed system is been built on standalone system with varying Ip and Port Number’s ,a set of 10 nodes with a base station has been built for research work .The Average delay achieved with SHA1 is 4.5.
