Vehicular Ad Hoc Networks (VANETs) are going to be an important communication infrastructure in our moving life. The design of routing protocols in VANETs is a significant and necessary issue for supporting VANET-based applications. However, due to high mobility, frequent link disconnection, and uneven distribution of vehicles, it becomes quite challenging to establish a robust route for delivering...
With the rapid development in internet and video coding technology, applications such as telesurgery and remote operations are becoming more and more popular. In such applications, any delay will significantly lower the performance and may sometimes lead to catastrophic results. As a result, low-delay video streaming is demanded in such applications. Previous works have explored and established several...
Enabling efficient vehicular wireless connections with wide coverage for vehicular applications has gained significant attentions in both academia and industry. In this paper, we study the TV white spaces (WS) supportive vehicular content distribution with Geolocation database, which is referred to as WhiteFi Infostations. Taking into account both the realistic content distribution requirements for...
In this paper, we present an analytical framework for offloading cellular traffic by outdoor WiFi network in the vehicular environment. Specifically, we consider a generic vehicular user with Poisson data service arrivals to download/upload data from/to the Internet through the cost-effective WiFi network (want-to) or the cellular network providing full service coverage (have-to). Under this scenario,...
The booming smart grid produces a large amount of data that should be transmitted to the utility control center (UCC), typically by means of the cellular network. This may pose a prohibitive transmission cost and choke the cellular network. As an effort to address this issue, we propose a vehicle assisted data delivery method to offload the cellular network, in which vehicles are utilized to carry...
Although multifractal describes the spectrum distribution of Singularity Exponent (SE), it loses the temporal information, and it's hard to describe the dynamics evolving process of non-stationary system. The time-varying singularity distribution indicates the spatial dynamics character of system. Therefore, the time-varying quadratic multifractal spectrum is proposed. Similar to the Wigner-Ville...
In this paper a novel multipriority reservation protocols for plastic optical fiber network is proposed. In conventional OCDMA system only allows finite units to transmit and access simultaneously according to the number of channels which be restricted by BER. To resolve this problem, a novel protocol based on slotted ALOHA is proposed in this paper. By using the reservation scheme and a distributed...
A notion of logic time and logic time stamp are introduced to control running order for single-period and multi-periods simulation system. Then a synchronous startup schedule strategy is designed, and its technology essential and implementation flow are discussed. According to the time stamp and the simulation logic time of interactive data, the measurement and compensation method of time-delay in...
