A RELIABLE APPLICATION LEVEL BROADCASTING PROTOCOL FOR VANET?

Many applications are built on broadcast communications, so efficient routing methods are critical for their success. Here, we develop the Distribution-Adaptive Distance with Channel Quality (DADCQ) protocol to address this need and show that it performs well compared to several existing multihop broadcast proposals. The high cost aggravates the inherent resource constraint problem in MANETs particularly in multimedia wireless applications. To proposal high anonymity protection, we suggest an Anonymous Location-based Efficient Routing protocol (ALERT). It s also called Reliable Application Level Broadcasting (RALB) protocol. RALB dynamically dividers the network field into zones and randomly chooses nodes in zones as intermediate relay nodes, which form a no traceable anonymous route. RALB proposals anonymity protection to sources, destinations, and routes. RALB has policies to successfully counter intersection and timing attacks. We theoretically analyze RALB for anonymity and efficiency. RALB achieves similar routing effectiveness to the GPSR geographical routing protocol. The DADCQ protocol utilizes the distance method to select advancing nodes.The performance of this method be contingent heavily on the value of the result threshold, but it is difficult to choose a value that results in good performance crossways all scenarios. an anonymous communication protocol that can provide intractability is needed to strictly ensure the anonymity of the sender when the sender communicates with the other side of the field Node density, spatial distribution pattern, and wireless channel quality all touch the optimum value. The node recognizes its neighbor as a node that inside the node’s radio range. Once the source need to send a packet, it usually stores the position of the destination in the packet header which will help in promoting the packet to the destination without needs to route discovery, route maintenance, or even alertness of the network topology.
