Exploring a new transport protocol for vehicular networks

The Future Internet will be very different from the current Internet. In particular, support for new networks such as vehicular networks, will be a key part of the new environment. Applications running on these networks will require low latency and high bandwidth, which must be provided in a highly mobile environment. The goal of this paper is to look at these issues as they have been addressed in the design and development of the Simple Lightweight Transport Protocol (SLTP) to support vehicular networking. The functions and workings of the protocol are examined in this paper as well as the ecosystem that is needed to provide low latency. A detailed set of preliminary results are presented and compared with a standard TCP implementation. SLTP was also ported to the Roadside Units of a Vehicle Ad-Hoc Network and results are presented for moving data to and from the Roadside Units. This work highlights the need for the Future Internet to place more resources at the edge of the core network to provide support for low latency in vehicular environments.
