“…Moreover, if {} l  are uncorrelated and uniformly distributed variables in [ , ]   , then, ( , ) G f t , will be a WSS process with respect to frequency and time 4 . Under the same conditions, the V-V channel is also first order stationary inside RTI and RBW 5 . Thus, small scale fading (variations within RTI and RBW) in V-V channels can be modelled by the well-established statistical tools for WSSUS channels as in [23] and [25].…”

We present a generic statistical characterization of the vehicle-to-vehicle (V-V) wireless channel by adopting a stochastic modeling approach. Our approach is based on the doubly underspread (DU) property of non-wide sense stationary uncorrelated scattering (non-WSSUS) wireless channels, with V-V channels pertaining to this category. DU channels exhibit explicit frequency and time intervals over which they are approximated as WSSUS. We call these intervals restricted time interval (RTI) and restricted bandwidth (RBW), and variations taking place inside them are characterized as small scale variations. Large scale variations take place outside RTI and RBW. In this paper, we focus on small scale variations, thus, our modeling finds its applicability within RTI and RBW. As practical V-V channels exhibit rapid

“…The RSUs are typically spaced 1 km apart along a 3 lane motorway stretch, which is in line with the Wireless Access for Vehicular Environment (WAVE) standard [18]. In [10], [19], the authors considered a V2V scenario where the CHs in a double cluster head (DCH) scheme were responsible for the formation/deformation, synchronisation and communication within the clusters.…”

“…Therefore, we need to: (a) determine the minimum buffer size of the CH which maintains at throughout the day; and (b) minimise the average packet delay by introducing sleep cycles type-II (Section 4-B). As a first step to achieve (a), we substitute from (10) in (12), then from (12) in (14) and subsequently rearrange (14), in terms of buffer size as (18) With the maximum number of vehicles ( ) representing the busiest hour, the offered load becomes highest i.e. .…”

The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. energy savings and 7.3 ms average packet delay over the day, resulting in respective improvements of 10% and 28% compared to the existing random sleep cycles. These improvements have been achieved under a very conservative operating delay bound for audio conferencing applications. However, modern compression and codecs, due to their leniency on Quality of Service (QoS), would potentially enable higher energy savings through the proposed sleep cycles.
