  3. 3. In a world of ubiquitous communication, people are more connected and mobile than ever before. Connect- ed Cars is one such example stemming from a users need to remain connected, even when on the move. A Connected Car is a car (or any moving vehicle) that is equipped with infrastructure to access external networks, maybe via wireless local networks, for example. This allows the car to share internet access to other devices both inside and outside the vehicle. Typically, such a car will have an Integrated Unit fitted with wireless devices and interfaces, to which end user devices like Smartphones, Laptops, etc., are connected (Figure 1). The wireless interface is used to get connected to a wireless network, which in-turn acts as a con- duit to get connected to an external network. Connected Cars can not only change the way people travel but also shape how businesses are run. The advertisement industry could get a new platform for revenue generation. The healthcare industry could close the distance barrier between doctors and patients. The education industry could bridge the gap between the quality of education in rural and urban populations. Traffic management could get a lot easier in future mega cities. This paper highlights some of those areas in light of both developing and developed economies. Case stud- ies are provided for the transport, healthcare, and education sectors, and the underlying challenges / open issues are discussed for each use case Connected Cars has been a concept that has been investigated and prototyped for quite some time now. The technological aspects of a connected car involving how the devices inside the car can be connected with the computing and application servers, and the use of computing power to access real time information and data, is well understood. Using high speed connectivity like LTE (Long Term Evolution) inside the car to provide seamless connectivity and mobility is increasing, coupled with cloud computing infrastructure. Capi- talizing on these various building blocks, this paper tries to explain a few use cases of connected cars, with particular relevance to India. Use cases are covered for applications in the field of transport, healthcare, and education. Business models are discussed in each of these applications to bring understanding on the vari- ous players involved in these scenarios. Major challenges are explained and the conclusion provides the next steps for how to take this discussion further. The paper also covers the significant characteristics of the wire- less network and the cloud computing system, the challenges involved, and the business issues. The paper focuses on how the next generation car can evolve into a sophisticated device, providing multiple services and how companies - like service providers, the auto-industry, content providers, and computing platform vendors can integrate themselves to achieve a common vision. 1. Introduction Abstract
  4. 4. In this section, we describe two use cases for connectivity on wheels, specific to the Indian context. Our belief is that these use cases are scenarios that can trigger application and business propositions across vendors who are 2. Use Cases for Connected Cars 2.1 Connectivity on Wheels Figure 1.

  5. 5. 2.1.1 Connected Bus 2.1.2 Ubiquitous Broker The second use case is the concept of the Ubiquitous Broker. In this case, imagine a stock broker, who is traveling in Mumbai and is trading in the Bombay Stock Exchange. The stock broker is very sensitive to price fluctuations on the stock exchange, and desires an up-to-date status, even when traveling. By a combina- tion of high speed network connectivity and cloud computing, it is possible for the broker to get the current information on stock prices and he/she will be able to trade even when on the move (see Figure 2). Hence, his/her connected car could become a virtual office. Consider a scenario where a lot of people travel by high-tech luxury buses for long distances. During the journey, passengers pass their time by watching movies in the bus but literally have no choice about what they would like to watch or listen to. In the Connected Bus scenario, assume that each passenger has a small smart screen in front of his/her seat, which is connected to the cloud via wireless connectivity available in the bus. This allows a whole new set of applications that each passenger can access - be it entertainment, net surfing, or even, work. People can watch movies, or the news, or play interactive games of their own choice. This type of connectivity is also helpful in bus-to-bus communication, where a bus breakdown can be com- municated to another bus and the necessary action can be taken to transport stranded passengers. Typical- ly, on highways there are traffic congestions owing to accidents and other reasons. In such cases, bus-to-bus communication can help drivers navigate alternate routes. This use case brings out a business model where a wireless network operator could have a tie up with the bus operator, and they both can have an agreement with a cloud computing vendor. Based on the demographic pattern of the people, movies of choice can be played by the vendors with a discount provided to the bus operator, thereby providing bulk discounts and increasing the revenue.
  6. 6. Let us take the first use case where the bus passenger requests a movie of his choice. The content provider in the cloud interacts with the wireless service provider based on the location of the passenger; and since this request is originating from a bus, the wireless service provider provides a QoS (Quality of Service) tunnel to the passenger, based on the agreement between the bus operator and the service provider. Once the trans- port characteristics are setup, the content provider can stream the required application to the passenger.(- See Figure 3 for more details). 2.1.3 Business Model wireless service provider luxury bus Compute Cloud Storage cloud Broker
  7. 7. Similarly, in the second scenario, the broker bids for a stock and sends out his negotiated value based on the value provided by the directory service in the cloud. This triggers the banking infrastructure or stock service to provide a transport QoS. This can be made possible by interacting with the wireless service provider to facilitate secure media transport. The bid is translated in to a transaction which is responded to by the banking service, and the deal is struck. In both these scenarios, the storage and computing cloud can be provided by cloud computing vendors, who can loan out storage and computing power as services to the other players in these transactions.

  8. 8. Healthcare is one of those critical areas where the advantages of this concept can help provide critical, on-the-move medical services for both developing and developed economies. Medical emergencies like road accidents, heart ailments, etc., can be diagnosed on the run, without delay. Apart from medical emer- gencies, the connected car can be used as a mobile hospital or e-Healthcare center that provides medical care to the masses in remote or rural areas. 2.2 E- Healthcare using Connected Cars Patient data can be maintained at the cloud server and can be made accessible anywhere and at any time if sufficient connectivity is provided. For example, a traveling medical consultant in a connected vehicle can access patient data, and so also can a specialist doctor in the hospital (see Figure 4). The service provider gateway facilitates access to the database from the cloud server using APIs. The security and integrity of the data is managed by the service provider along with other user authentication mechanisms. The connected car can access the service provider gateway using the nearest wireless network. 2.2.1 Remote Doctor Connected Car equipped with healthcare facility Wireless Network Doctor in City Hospital Wireless Service ProviderCloud computing Facility Patient Database Manager
  9. 9. Consider an example where a connected car, which is a mobile hospital, reaches a remote area where a patient is located. The medical consultant in the mobile hospital then connects the patient to the doctor through an interactive video session. The doctor can then do a real time diagnosis of the patients condition using the medical history of the patient available from the cloud server. Based on the doctors findings, the consultant can even do minor operations / surgeries and provide prescriptive treatment and more. This approach proves very useful in cases of epidemics, minor surgeries, and diagnosis based on laser tech- nology. Another great advantage is that the treatment can be made
