Rateless Coding Data Dissemination with Handshake in VANETs

Data dissemination in VANETs has recently attracted much attention. The important problem is the proper protocol performance in different network density. The most of existing protocol are struggling to perform well in sparse networks. In this paper, a new protocol was purposed for data dissemination in VANETs. This protocol is simple and does not struggle with problem in sparse network. A proper handshaking algorithm is also designed for congestion avoiding during vehicle's communication. The results show that purposed algorithm success depends on vehicle's speed. If the vehicle's speed is increased, the vehicle should travel more distance for message decoding. The vehicle's speed increasing also causes less delay in message decoding. The vehicle's speed should be set for balance between delay and decoding distance.
