Strengthening the Integrity of Forwarding First Communication Using Forward Key Chain and Bloom Filter in the Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are collections of sensor nodes that can help people monitor things wirelessly, replacing the need for human presence in hard-to-reach areas. While forwarding first communication reduces delays among nodes, it lacks a security mechanism. Since have limited resources, using complex measures shorten their lifetime. This study proposes protocol modification forward keychain and Bloom Filter Vector (BFV). The sender is required to send BFV every message exchange. process sending separated increase size payload each communication. results show while overhead verification time an acceptable level, larger integrity guaranteed.
