Abstract

The concept of 'Internet of things' has not been restricted to human beings and household articles, but also to vehicles. Connected cars are those which have the presence of devices in an automobile that connect the devices to other devices within the car/vehicles and or devices, networks and services outside the car including other cars, home, office or infrastructure. According to Gartner, Inc, by 2020, there will be a quarter billion connected vehicles on the road, enabling new in-vehicle services and automated driving capabilities. During the next five years, the proportion of new vehicles equipped with this capability will increase dramatically, making connected cars a major element of the Internet of Things (IoT).

As of today, Connected cars communicate majorly on the internet to share or receive content. For example, in-house entertainment or information from/to the web. However, we have also found that not everytime, it is essential for the cars to connect to the internet. In the world of connected cars, the other cars on the road can also be having the information/entertainment required. Hence one car can get the information from another car on the road. However to do that, the two vehicles should communicate i) to know who has the content that the initiator car is interested in. ii) to negotiate a fair deal to receive the content iii) to transfer the content as fast as possible using heterogenous devices (in the case of two moving cars) iv) to identify the car from which one needs to receive the content from the multitude of cars around

In this idea, we propose a new negotiation protocol which would enable effective data transfer to/from the multitudes of connected cars prior to the actual transfer.

A novel negotiation protocol for speeding connected car communication
Core Idea:
A novel negotiation protocol based on the speed of both the participating cars, their mutual bandwidth capacity, the cost of data, their range, the size of the content and the information tags they contain in order to effectively share interested infotainment data between two speeding Connected cars.

Usecases:
1. Holiday Travellers are keen on gaining co-travellers real-time feedback, reviews about the Holiday location, nearby places of interest and related photos or videos, restaurants, shopping canters, hospitals etc. Social media based feedback are not real-time in nature and need internet access. Our idea facilitates seeking dynamic information of interest through information exchange between the moving or stationary vehicles in the vicinity.


2. The cost based negotiation protocol described in our idea paves way to an exciting new revenue model. For example, third-party advertising and commercial agencies can advertise about homestay and resorts near to tourist locations, along with reviews from other customers. Agencies collect service charges for the same, in turn they can offer discount coupons from the vendors.

Advantages:
1. The novel negotiation protocol discussed ensures dynamic data exchange based on factors like speed, data transmission rates, user's interest, range of the vehicles, data size and cost model. This reduces wasted bandwidth due to receiving partial content or content not of interest.

2. The negotiation protocol enables the vehicles/users to find the desired content in the large volume of data(multitudes of cars having content). Once the interested content is known, the vehicle can select the content owner from which to receive the data based on associated cost of data sharing This brings in a new revenue model for publishers and consumers of content.

3. Enabling data exchange based on factors like data transmission rate and range and speed of participating vehicles brings in more reliable data transmission.

4. Since the data transmission is between vehicles and not with stationary road side units, the content is more dynamic and of more 'local' relevance (eg: reviews on tourists spots or restaurants just visited in the nearby areas). Hence such a negotiation protocol allows vehicles to share more customized data which is locally available rather than connecting to a centralized unit (like internet)

5. The negotiation protocol provisions for transferring content using heterogeneous devices (like smartphones, tablets etc.) present in the vehicles. In cases where data bandwidth required for transfer is higher and the vehicles have published the presence of additional devices with available bandwidth, then data transfer is multiplexed into the heterogeneous devices. This enables faster data transmission rates and efficiently utilizes available bandwidth.

Each car participating in the connected cars scenario should hav...
