Internet-based vehicular ad hoc network (IVANET) is an emerging technique that combines a wired Internet and a vehicular ad hoc network (VANET) for providing universal information and service accessibility. A key design optimization technique in IVANETs is to cache the frequently accessed data items in a local storage of vehicles. Since vehicles are not critically limited by the storage/memory space...
Wireless sensor networks consist of low-cost and low- power radio devices and are deployed in open and unprotected areas. Privacy is becoming one of the major issues that jeopardize the successful deployment of wireless sensor networks. While confidentiality of the message can be ensured through content encryption, it is much more difficult to adequately address the source-location privacy. For wireless...
From agriculture to industry, from the office to our homes, Wireless Sensor Networks (WSNs) are becoming a part of everyday life in many application areas. In typical WSN applications, the sensor nodes are fixed and interconnected amongst each other and to the outside world on a permanent basis. However, in certain types of applications, where the area to sense is wide and sensors are sparsely distributed,...
Ubiquitous Internet connectivity is very important in present environment. A lot of research has been done to extend Internet connectivity to vehicular ad hoc networks (VANETs). The biggest challenge to achieve this goal is the requirement of pervasive fully networked roadside infrastructure. This requirement is difficult to achieve especially during the initial deployment phase of vehicular networks...
Vehicular Ad Hoc Network has recently been considered as attractive network architecture to provide various services ranging from road safety to entertainment applications. In this paper, we propose an IEEE 802.11 based multihop broadcast protocol to address the issue of safety message dissemination in Vehicular Ad Hoc Networks. This position- based protocol adopts a repetitive 2-partition method...
In this paper, we propose a location-release signature scheme based on bilinear pairings for vehicular ad hoc networks (VANETs). Location-release signature is a capsule signature signed by a source location server that becomes valid after the signature arrives at a specific destination location, where a location server publishes some trapdoor information associated with such a destination location...
