The Internet of Vehicles (IoV) has become an indispensable part of a smart city, which can provide useful traffic information to supervise and guide drivers in metropolis. However, as the traffic data scales to a great volume, it becomes difficult for conventional database management tools to meet the requirement of massive data analysis. HBase is an open source, non-relational, distributed database...
With the explosion of vehicles, the concept of Internet of Vehicles (IoV) has drawn increasing concern among academics. The IoV refers to extracting and processing information from massive data which are gathering from vehicles and their surrounds. And an integrated IoV system which is reliable on data storage and efficient on data processing is indispensable. In this paper, we design a distributed...
Small cell is a flexible solution to satisfy the continuously increasing wireless traffic demand. In this paper, we focus on on-off switch operation on small cell base stations (SBS) in heterogenous networks. In our scenario, the users can either choose SBS when it is active or macro cell base station (MBS) to transmit data. Start-up energy cost is considered when SBS switches on. The whole network...
In this paper, we focus on the energy consumption problem in heterogeneous networks with on-off switch operation for small cell base stations (SBS). In our scenario, the users in the small cell can either choose SBS when it is awaken or macro cell base station (MBS) to transmit data. The start-up cost is considered when SBS switches on. We suppose both the transmission power and the users' number...
