WSEECM: Wireless Sensor Network System with Secure and Energy Efficient Cluster Management

Increasing network lifetime of energy-constrained sensor nodes is a crucial issue, different researches are directed just to increase network uptime either by changing network topology, providing shortest routing decisions or by efficiently selecting cluster head in a cluster. Data forwarding by aggregating data from all nodes in a cluster and forwarding it to other nodes in minimum hops reduces bandwidth usage. Wireless Sensor Network System with Secure and Energy Efficient Cluster Management (WSEECM) elects cluster head on the basis of residual energy, the distance of a node to base station and a maximum number of nodes in its range. Cluster Head selection is secure, less energy and time-consuming increases the network lifetime of the sensor network. Security is another major issue in such network, for secure data transmission nodes encrypt their data before forwarding it and ECC algorithm is used for encryption and decryption purpose. Each time when aggregated data is sent to processing station it is verified by its cluster attribute by Relay Cluster Head (RCH). If the cluster head is detected as malicious it is hence discarded and further operations of that cluster are conducted by respective RCH.
