Survey of MIRP for Vehicular Ad-Hoc Networks in Urban Environments

Vehicular communication is attracting growing attention from both academia and industry, owing to the amount and importance of the related applications, ranging from road safety to traffic control and up to mobile entertainment. The vehicular ad-hoc network is an emerging new technology. Many VANET routing protocols use a carry-and-forward mechanism to deal with the challenge. However, this mechanism introduces large packet delay, which might be unacceptable for some applications. In this proposed system, we first analyze the unique feature of urban VANET that vehicles have different types, and move like clusters due to the influence of traffic lights. So the concept of using buses as the mobile infrastructure to improve the network connectivity is proposed. We also develop a novel routing protocol named as MIRP (Mobile Infrastructure Routing Protocol) which makes full use of buses, making them a key component in route selecting and packet forwarding.
