A Study of Mobile Edge Computing System Architecture for Connected Car Media Services on Highway

2018 KSII Transactions on Internet and Information Systems  
The new mobile edge network architecture has been required for an increasing amount of traffic, quality requirements, advanced driver assistance system for autonomous driving and new cloud computing demands on highway. This article proposes a hierarchical cloud computing architecture to enhance performance by using adaptive data load distribution for buses that play the role of edge computing server. A vehicular dynamic cloud is based on wireless architecture including Wireless Local Area

The main advantages of the proposed architecture include both a reduction of data loading for top layer cloud server and effective data distribution on traffic jam highway where moving vehicles require video on demand (VOD) services from server. Through the description of real environment based on NS-2 network simulation, we conducted experiments to validate the proposed new architecture. Moreover, we show the feasibility and effectiveness for the connected car media service on highway. (MECS) on highway to refer to a bridge server system that supports media files to vehicles existed in communication coverage directly. Cisco [11] [12] [13] recently delivered the vision of MECS to enable applications on billions of connected devices, already connected in the Internet of Things. Both cloud and MECS provide data, computation, storage, and application services to end-users. The distinguishing MECS characteristics include its proximity to end users, its dense geographical distribution, and its support for mobility. Services can be hosted at end devices such as set-top-boxes or access points. MECS provides low latency, location awareness. In addition, MECS improves quality of service for streaming and real-time application, and supports heterogeneity. In our view, existing for computing based architectures can be modelled by a simple level architecture where each vehicle attached to the bus as mobile edge computing device, and mobile edge computing devices could be interconnected, and each of them is linked to the cloud [14] . It is defined that the MECS model for the data communication between the bus and cars are on the high way and this environment shows more developers to bring their own applications and connectivity interfaces at the edge of the network. This proposed architecture of MECS allows application to run as close as possible to sensed actionable and massive data as possible. The major contributions of this paper are as follows: 1. The state-of-the-art models of MECS using bus on highway are shown. 2. A new MECS architecture for VOD service and vehicular status information are proposed. These services were considered as next trend of in-vehicle entertainment system and autonomous car. 3. In traffic jam scenario, the proposed network simulation is examined and the load distribution performance of the proposed architecture is evaluated simply. 4. Through NS-2 real environment based simulation, it is found that the proposed architecture is needed on highway. It showed that network performance of proposed method is superior to ordinary communication system. This paper is organized as follows. Section 1 provides motivation and an overview of related work Section 2 presents the proposed vehicular environment on highway and describes the architecture based on MECS using Bus.
