The purpose of this study is to explore the digital divide that appears in the mobile Internet use by farmers and fishers. To this end, we first analyzed the impact of farmers and fishers' attitudes toward technology, material access, and skills on the use of mobile social media. In addition, the digital divide was identified according to the population, socioeconomic factors among farmers and fishers, and the divide and the cause of the mobile Internet use among both part- and full-time farmers and fishers were analyzed. As a result of empirical analysis using the <2018 Report on the Digital Divide>, attitudes, material access, and content-related skills had a significant effect on the use of mobile social media. Also, the digital divide was found in different age groups and residential regions. There was also a significant difference in the use of mobile social media between part- and full-time farmers and fishers, and this divide was caused by attitudes toward new technologies. Based on these results, this study presented policy implications such as the need for education on informatization for farmers and fishers, support for underdeveloped rural communities, and technical support for full-time farmers and fishers in order to bridge the digital divide.

As the wireless internet applications are spreading more fast and the mobile devices are being used increasingly, it has recently been activated to develop a variety of contents for mobile service. Mobile services can be enjoyable whenever and wherever on would like to. They became so universal that they might reach all the area where the wire has never approached before. This study is to suggest a mobile game system based on the technology called WIPI(Wireless Internet Platform for Interoperability), which can be easily available to anyone who would like to enjoy it. Game contents to use WIPI can allow the mobile carriers to provide users to download the common mobile application throughout the wireless web by sharing the internet platform. This can eventually lead to the generalization of transforming west game contents into WIPI-based. Therefore, the market of WIPI-based game contents will be expected to grow at high speed and its significance deserves to be considered for commercialization.

The use of mobile devices is increasing in multimedia applications. The multimedia contents are delivered to mobile users over heterogeneous networks. Due to fluctuation in bandwidth and user mobility, the service providers are facing difficulties in providing Quality of Service (QoS) guaranteed delivery for multimedia applications. Multimedia applications depend on QoS parameters such as delay, bandwidth, and jitter to offer better user experience. The existing schemes use the single source and multisource delivery but are unable to balance between stream quality and network congestion for mobile users. We proposed a Quality Oriented Multimedia Content Delivery Scheme (QOMCDS) for the mobile cloud to deliver better quality multimedia contents for the mobile user. The multimedia contents are delivered to the mobile device based on the device's parameters and network environment. The objective video quality assessment models like Peak Signal-to-Noise Ratio (PSNR), Structural Similarity (SSIM), and Video Quality Measurement (VQM) are used to measure the quality of the video. The client side Quality of Experience metric such as Startup delay, Rebuffering events, and Bitrate switch count was used for evaluation. The proposed scheme is evaluated using dash.js and is compared to existing schemes. The results show significant improvement over existing multimedia content delivery schemes.

Wireless sensor networks (WSN) are self-organized networks that typically consist of thousands of low-cost, low-powered sensor nodes. The reliability and availability of WSNs can be affected by faults, including those from radio interference, battery exhaustion, hardware and software failures, communication link errors, malicious attacks, and so on. Thus, we propose a novel multi-agent fault tolerant system for wireless sensor networks. Since a major requirement of WSNs is to reduce energy consumption, we use multi-agent and mobile agent configurations to manage WSNs that provide energy-efficient services. Mobile agent architecture have inherent advantages in that they provide energy awareness, scalability, reliability, and extensibility. Our multi-agent system consists of a resource manager, a fault tolerance manager and a load balancing manager, and we also propose fault-tolerant protocols that use multi-agent and mobile agent setups.
