In order to reduce a road monitoring cost, we propose a system to monitor extensively road condition by cyclists with a smartphone. In this paper, we propose two methods towards road monitoring. First is to classify road signals to four road conditions. Second is to extract road signal from a smartphone’s accelerometer in three positions: pants’ side pocket, chest pocket and a bag in a front ba...

Vehicular Ad Hoc Networks (VANETs) are characterized by high mobility of nodes and volatility, which make privacy, trust management, security challenging issues in VANETs' design. In such networks, data can be exposed to a variety attacks, the most dangerous is false information dissemination, threatens safety efficiency transportation systems. False emergency messages injected inside attackers...

Access control of message is required when certain selected vehicles are granted access to information, instead of all vehicles within communication range. In these situations an access policy (consisting of attributes as road situation and vehicle type) is built into the vehicle and messages are encrypted using these access policies. Only valid vehicles possessing these attributes are able to ...

Vehicular communications disclose rich information about the vehicles and their whereabouts. Pseudonymous authentication secures communication while enhancing user privacy. To enhance location privacy, cryptographic mix zones were proposed to facilitate covertly transition new ephemeral credentials. The resilience (syntactic semantic) pseudonym linking (attacks) highly depends on geometry of zo...

This paper considers the problem of constructing classifiers for road side assistance capable of providing reliability values for classifications of individual instances. In this context we analyze the existing approaches to reliable classification based on the typicalness framework [14, 25]. As a result we propose an approach that allows the framework to be applied to any type of classifiers s...

In this paper, we present a reputation assisted trust management mechanism for vehicular ad hoc network (VANET) using privacy preserving trusted group formation. In a VANET, vehicles or road side units can be malicious or malfunction making security essential. A distributed trust management provides a lightweight security alternative to existing security techniques especially in VANET. The trus...

Vehicular Ad hoc Network (VANET) is one type of Mobile Ad hoc Network (MANET). In VANETs, vehicles are connecting to computer networks. VANETs have dynamic nodes in the form of moving vehicles and static nodes in the form of Road Side Units (RSU). Movements of vehicles are limited to road layouts and fast compared to other ad hoc networks. Hence, frequent disconnections are happening in the com...

Internet of Vehicles (IoV) systems are vulnerable to a wide range attacks because the lack security measures. IoV can be infiltrated by malicious and unauthorized nodes, which cause authenticity, accessibility, privacy shared information resources compromised. Indeed, use an access control system help; as result, it is unable respond such on time. This paper introduces artificial intelligence-e...
