MHAV: Multitier Heterogeneous Adaptive Vehicular Network with LTE and DSRC

Vehicular positioning enhancement using DSRC

Road transportation injuries, environmental pollution, and wasted energy and time in traffic congestion cause considerable cost to society. Some examples are the $115 billion cost of United States traffic congestion in 2009 and its predicted $23 billion annual cost in Australia by 2020. Intelligent Transportation Systems (ITS) are increasingly being considered to mitigate these impacts. The ben...

Interoperability Framework for Vehicular Connectivity in Advanced Heterogeneous Vehicular Network

Advanced heterogeneous vehicular network (AHVN) is a promising architecture for providing vehicular services in the next generation of vehicular networks. AHVN is an integrated architecture between vehicular ad hoc networks and existing cellular wireless networks. In this work, we propose a Multihop vehicular connectivity model in V2V system, which depends on the physical characteristics of the...

Performance Evaluation for DSRC Vehicular Safety Communication

In this paper, an analytic model is proposed for performance evaluation of vehicular safety related services in dedicated short range communications (DSRC) system on highway. The generation and service of safety messages in each vehicle is modeled by an M/G/1 queue. But since vehicles share a medium, the service time distribution of a message needs to take contention and backoff into account. W...

Advanced Heterogeneous Vehicular Network for Emerging Vehicular Services

LTE Heterogeneous Network: A Case Study

Long terms evolution (LTE) allows using new and wider spectrum up to 20MHz with high data rates and lower latency. This paper provides analysis of the concept of heterogeneous networks as compared to homogenous networks on a realistic scenario of Mosul city and discusses the need for an alternative deployment model and topology to enhance the performance of network. It is clearly demonstrating ...
