A packet has to be delivered within a distinct time limit as data delivery is a critical issue in a wireless network. In emergency situations, real-time data distribution of multimedia file is addressed using wireless network. The real-time data examined here are image and audio files and these files are broken into sequence of packets and forwarded to the destination peer node based on a Priority algorithm. Prioritized data dissemination processes the sequence of packets to be forwarded based on permanent priority scheduling. The packets are encrypted based on Trust-based Public key management using public key generated in key generation phase and decrypted at the receiver end. The simulation results prove that the proposed technique has the enhanced and secured data transmission. The design of the network requirements and detailed experimental results are presented.
