Abstract:
Vehicular ad-hoc networks (VANETs) have envisioned various applications that substantially improve traffic safety and efficiency along the roads and highways. There are on-going projects both in academia and industry to standardize VANETs and to start off their real-life deployment. Despite the huge benefits envisioned by VANETs, they cannot be readily deployed as they are subjects of serious security and privacy concerns. These security and privacy concerns should be addressed and thus VANETs require a sound Identity management architecture before their anticipated deployment. Current resea

Abstract:
In order to realize effective infotainment systems for vehicles, we need to have context-aware applications that use the latest (live) information for an enhanced user experience. Such up-to-date information is now abundantly available on the Internet, due to the explosive growth of the Web 2.0. In earlier times, it was difficult and expensive for vehicles to connect to the Internet. Recent advances in vehicular ad-hoc networks (VANETs) have enabled vehicles to connect to the Internet through road side infrastructures, with little to no additional cost.

Abstract:
Current geocasting algorithms for VANETs are being designed to enable either private or reliable communications, but not both. Existing algorithms preserve privacy by minimizing the information used for routing, and sacrifice message delivery success. On the other hand, reliable protocols often store node information that can be used to compromise a vehicle's privacy. We have designed two private and reliable geocasting protocols for VANETs that ensure confidentiality. One is a probabilistic algorithm that uses direction-based dissemination, while the other is a deterministic algorithm that us

Abstract:
User desire for ubiquitous applications on-board a vehicle motivates the necessity for Network Mobility (NEMO) solutions for Vehicular Ad-Hoc Networks (VANETs). Due to the dynamic topology of VANETs, this approach incurs excessive infrastructure cost to maintain stable connectivity and support these applications. Our solution to this problem is focused on a novel NEMO-based Network Architecture where vehicles are the main network infrastructure. Within this Architecture, we present a Network Criticality-based clustering algorithm, which adapts to mobility changes to form stable self-organizing

The research areas of VANET can be divided into two major parts: safety application and comfort application. For example of safety application, if the car has crashed on the highway, the emergency information can be propagated as soon as possible to inform the cars behind the accident. And for th

Since the highly mobile traffic topology of vehicles, most existing routing protocols for wireless communications are not suitable for VANET .The roadside unit (RSU) is not effective to search the moving vehicles of unknown position on the urban road due to the high relative speed between vehicle and RSU.

Vehicles can connect to the Internet by accessing Basic Station (BS), because of their fast mobility, vehicles can only connect to a BS for a very limited amount of time. The time for a vehicle to obtain an IP address via Dynamic Host Configuration Protocol (DHCP) from BS is a main part of the connection time. On the other hand, the VANETs are high mobility patterns that cause frequently and fast topology changes and also frequently disconnection. To solve these probl

Connectionless approach (CLA) is a road-based single path routing protocol. If a route disconnects, it has to create a new route. Ad-hoc on-demand multipath distance vector (AOMDV) and node-disjoint multipath routing (NDMR) are multipath routing protocols. They can switch to another route if ones route is disconnected. However, since AOMDV and NDMR are node-centric routing protocols, a route is easier to

We also analyze the security and efficiency of our schemes. After analyze, we can conclude that our OT scheme is not only secure but also more efficient in bandwidth consumption than all of the other existing oblivious transfe

The basic idea is to allow arbitrary vehicles to broadcast ad hoc messages (e.g. traffic accidents) to other vehicles and remind drivers to change their route immediately or slow down to avoid dangers. However, some concerns of security and privacy are also raised in this environment. Messages should be signed and verified before they are trusted while the real identities of vehicles should not be revealed to guarantee

Vehicular Ad hoc Networks (VANET) consist of radio-equipped vehicles and roadside units (RSU) and support many safety and commercial applications. Multi-hop forwarding can extend the communication range of both RSUs and vehicular broadcasts. Recently, the use of Positive Orthogonal Codes (POC) as transmission patterns of repetition-based broadcast medium access control (MAC) for safety messages has been proposed.
