Nowadays, and Internet of Lights (IoL) can be used to help a variety of lights in home, building, factory, city, and so on. The achievement of wireless communication technologies have brought convenience and amazing services to users. The hybrid use of wireless technologies in a system is not a novel idea, however, in this paper, we introduce the feasible OCC protocol based on Wi-Fi technology and OCC technology that is emerging technology nowadays. Various type of LEDs that implemented based on OCC technologies are connected via an MQTT (Message Queue Telemetry Transportation) broker to bring a promising service of light that allows smartphone users to receiving, control and monitoring data with augmented reality user experience. Demonstrations of the system along with implemented software and hardware are given to illustrate the feasibility of our system.

Distributed Denial of Service (DDoS) attacks are intense and are targeted to major infrastructure, governments and military organizations in each country. There are a lot of mitigations about DDoS, and the concept of Content Delivery Network (CDN) has been able to avoid attacks on websites. However, since the existing CDN system is fundamentally centralized, it may be difficult to prevent DDoS. This paper describes the distributed CDN Schema using Private Blockchain which solves the problem of participation of existing transparent and unreliable nodes. This will explain DDoS mitigation that can be used by military and government agencies.

Sound propagating through shallow-water waveguide undergoes inter-symbol interference (ISI) by multiple interactions with sea surface and bottom interfaces. Time reversal techniques using an array of spatially separated receivers have been widely used to reduce the effect of ISI. However, the time reversal method requires a large-size receiver array to improve the communication performance, which results in the degradation of space efficiency. The vector sensor measures acoustic pressure signal as well as x, y, and z-components of the particle velocity at a single point, and these signals can be used as a single-input multiple-output system (SIMO) for underwater acoustic communication. An underwater communication experiment using a vector sensor was made as part of the Korea Reverberation Experiment (KOREX-17) on May 24–25, 2017 in shallow water at location 34°43’ N, 128°39’ E. The communication results show that proposed technique(the block-based time reversal technique using the vector sensor) is useful in the time varying shallow water.
声音在浅水波导中传播时，由于与海面和海底界面的多重相互作用，会产生码间干扰。利用空间分离接收器阵列的时间反转技术已被广泛用于减少ISI的影响。然而，时间反转方法需要大尺寸的接收阵列来提高通信性能，从而导致空间效率的下降。矢量传感器在单点处测量声压信号以及粒子速度的x、y和z分量，这些信号可作为单输入多输出系统(SIMO)用于水声通信。作为韩国混响实验(KOREX-17)的一部分，于2017年5月24日至25日在34°43 ' N, 128°39 ' e的浅水区进行了使用矢量传感器的水下通信实验。通信结果表明，所提出的技术(使用矢量传感器的基于块的时间反演技术)在时变浅水中是有用的。

This paper proposes a multipath selection method for maximum ratio combining to improve bit error rate (BER) performance in code division multiple access (CDMA) experiencing underwater long multi-path channels. To select optimum paths, BERs are calculated for each multipath and the optimum multipaths that exhibit the minimum BER are selected. Computer simulation shown that the proposed method has better BER performance than a conventional threshold generalized selective combining (T-GSC).

Named data networking (NDN) is one of the future Internet architecture, which can well support smart home. The existing NDN-based smart home system has realized the device interconnection, but they lack of the flexibility of user control. In this paper, we have designed a user-driven smart home control system based on NDN exemplified by lighting and music player control. The system provides an interactive experience in a user-driven mode.

Spectrum sensing is the key technology in cognitive radio networks. This paper focused on the spectrum sensing in cognitive cloud networks and proposed a cooperative spectrum sensing algorithm based on phase compensation to improve the spectrum sensing performance. In the algorithm, the received signals in the sensing nodes are sent to the cloud, compensated in phase and combined into one signal. Then, the combined signal is used to test the hypothesis, whether the primary user is present. It uses all available information of all sensing nodes and improves the performance of spectrum detection effectively. The simulation results show that the proposed algorithm has 2–4 dB advantage in signal-to-noise ratio over other algorithms.

IEEE 802.11 WLAN Access Points(APs) are configured in the 2.4GHz band extensively to cater for the needs of all WiFi-enabled devices. In densely populated areas this causes considerable interference amongst the APs since there are only three orthogonal channels. Downlink data throughput reduces due to co-channel and overlapping channel interference. Efficient channel selection is a significant problem due to the dynamic wireless environment. Our proposed Dynamic Channel Selection(DCS) algorithm selects the optimal channel based on the periodic scan of the environment by a co-located monitoring radio unit. Frequent switching of channels is also reduced to maintain the AP's performance and stability. It is an innovative solution, readily applicable to the existing WLAN standard not necessitating any change in IEEE 802.11 MAC Layer. Our results show an improvement of up to 35% in the data throughput in six different real-time network scenarios.

This paper proposed a new integrated image segmentation method for MRI brain images. In this method we have used a new transformation called Contourlet Transform which is integrated with canny edge detector. For a better segmentation we have applied an enhancement function on the contourlet coefficients before applying canny edge detector. The experimental results shows that using canny edge detector after enhancing the image by contourlet transform along with an enhancement function, the brain MRI image can be segmented very efficiently which can outperforms other conventional methods.

This paper presents a scheme for crossing an intersection with no traffic light where multiple autonomous vehicles coming from different lanes must travel without collision. The focus of this paper is on the design of the reservation-based scheduling algorithm that determines the trajectories of the vehicles at the intersection under the assumption that the vehicles move at a predetermined constant speed in the intersection. Simulation shows that our solution can effectively schedule the entrance of the vehicles to the intersection and maintain the minimum distance between vehicles while traveling in the intersection. It is also shown that our proposed algorithm is fast enough to be used in real time.
