This paper investigates the information dissemination process in wireless communication networks formed by vehicles. As vehicles are moving constantly, a vehicular ad-hoc network exhibits a highly-dynamic network topology and a fast-changing radio environment. These distinguishing characteristics result in random and unreliable wireless connections between vehicles. Consequently, vehicles need to...
Using vehicles as sensors for traffic and environment monitoring is a new paradigm that opens the way to worthwhile applications. Data collected on board are usually delivered through the cellular network, with the consequent overloading risk. This paper focuses on the alternative adoption of short range vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications, with particular reference...
To incorporate cooperative diversity, Cooperative Extended Balanced Space-Time Block Codes (CEBSTBCs) have been proposed in the literature, providing full rate and full diversity when one or more feedback bits are sent back via feedback channel. Due to construction technique of the CEBSTBC, a relay out of N relays does not contribute the coding gain. To prevent this, the CEBSTBC with relay selection...
Wireless vehicular networks have received significant attention. As vehicles are increasingly equipped with onboard sensors, large-scale urban monitoring with vehicular networks becomes attractive. To facilitate better monitoring, it is highly desirable that sensory data of the vehicles can be gathered with high fidelity. Deploying wireless relays is a cost-effective approach for connection enhancement...
