“…there exists no other node between the transmitter and the receiver. Indeed, while a lot of work is still dedicated to characterising the exact overall network connectivity for mmWave communications V2V in urban setting [27], it is known that intermediate vehicles create significant blockage and a severe attenuation of the received power for vehicles past near neighbours [28,31]. Thus the routing strategy considered is a nearest neighbor routing.…”

We characterize trade-offs between the end-to-end communication delay and the energy in urban vehicular communications with infrastructure assistance. Our study exploits the self-similarity of the location of communication entities in cities by modeling them with the hyperfractal model which charaterize the distribution of mobile nodes and relay nodes by a fractal dimension d F and d r , both larger than the dimension of the embedded map. We compute theoretical bounds for the end-to-end communication hop count considering two different energy-minimizing goals: either total accumulated energy or maximum energy per node. Let δ > 1 the attenuation factor in the street, we prove that when we aim to a total energy cost of order n (1−δ)(1−α) the hop count for an end-to-end transmission is of order n 1−α/(d F −1) , with α < 1 is a tunable parameter. This proves that for both goals the energy decreases as we allow choosing routing paths of higher length. The asymptotic limit of the energy becomes significantly small when the number of nodes becomes asymptotically large. A lower bound on the network throughput capacity with constraints on path energy is also given. We show that our model fits real deployments where open data sets are available. The results are confirmed through simulations using different fractal dimensions in a Matlab simulator.Keywords Wireless Networks • Delay • Energy • Fractal • Vehicular Networks • Urban networks.

“…Extending the acquired knowledge from channel sounding and evaluation measurements performed inside anechoic chambers, the evaluation of outdoor V2I performance adds realism to the tested scenarios. Moreover, such results can then be used to validate and optimise the current channel models based on stochastic and deterministic methods [10], [11]. The specific scenario of interest is the communication path from an enclosed pedestrian bridge that connects the second floors of two departmental buildings on the University of Warwick's central campus (the International Manufacturing Centre and the Energy Innovation Centre) to the pavement along Lord Bhattacharyya Way towards the National Automotive Innovation Centre (NAIC).…”

High throughput wireless communication between vehicles and infrastructure will rely on millimeter-wave carriers and technology, which provide access to large bandwidths whilst still being able to establish stable links over distances of hundreds of meters. The work presented here, evaluates the quality of such signals in a mini-urban campus environment, by comparing detailed channel sounding results with signal quality parameters such as the error vector magnitude and the established data throughput. This provides insights into the relationships between fundamental parameters used to establish channel models and the quality of service parameters used in applications and standards. For the environment investigated, a strong threshold dependence of the signal quality on the received power is observed and explained in detail.

We characterize trade-offs between the end-to-end communication delay and the energy in urban vehicular communications with infrastructure assistance. Our study exploits the self-similarity of the location of communication entities in cities by modeling them with an innovative model called "hyperfractal". We show that the hyperfractal model can be extended to incorporate road-side infrastructure and provide stochastic geometry tools to allow a rigorous analysis. We compute theoretical bounds for the end-to-end communication hop count considering two different energy-minimizing goals: either total accumulated energy or maximum energy per node. We prove that the hop count for an end-to-end transmission is bounded by 𝑂 (𝑛 1−𝛼/(𝑑 𝐹 −1) ) where 𝛼 < 1 and 𝑑 𝐹 > 2 is the fractal dimension of the mobile nodes process. This proves that for both constraints the energy decreases as we allow choosing routing paths of higher length. The asymptotic limit of the energy becomes significantly small when the number of nodes becomes asymptotically large. A lower bound on the network throughput capacity with constraints on path energy is also given. We show that our model fits real deployments where open data sets are available. The results are confirmed through simulations using different fractal dimensions in a Matlab simulator.
