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.

In this paper, we introduce a new indoor localization system that receives a reference information from LED lamps and utilizes smart-phone sensors in tracking the device. To receive data from LED lamps placed at high ceiling, a digital auto zoom based optical camera communication (OCC) scheme is used in increasing the transmission distance. In addition, a magnetic sensor, a gyro sensor, and an acceleration sensor are effectively combined to realize a precise pedestrian dead reckoning (PDR) system. In this paper, we provide algorithms to implement the proposed schemes and show the experimental results.

In this paper, we propose a new color medical image encryption method using two-dimensional chaotic map and C-MLCA. The two-dimensional chaotic map is a structure with self-preserving properties, which moves the position of the pixel and encrypts the image. C-MLCA uses a maximum length PN sequence based on the properties of CA. The sequences with unpredictably complex rules create a basis image and the basis image is XOR-computed with the original image. That is, C-MLCA encrypts the image by changing the eigenvalues of the pixels through the computation process. Using these two features, we introduce an effective encryption method to overcome the limitations of the existing encryption methods. By comparing and analyzing the encrypted image with the original image, we were able to confirm that the proposed encryption method has a high level of stability and security.

The scalability challenge of many problems in massively -dense wireless sensor networks may be mitigated from a macroscopic perspective. One example is the weak formulation of the load-balancing routing problem, which solution can be used to route information. Hence, a routing algorithm, the distributed Gauss-Seidel iteration (DGSI), was proposed to coordinate sensors to solve the weak formulation iteratively. In this paper, we propose the atomic red-black distributed Gauss-Seidel iteration with finite element method (ARB-DGSI-FEM) to eliminate the early termination problem of DGSI due to the presence of holes, and thus improve the accuracy of numerical solutions. In addition, ARB-DGSI-FEM allows the values of unknowns to be updated in the red-black order to achieve the maximum degree of parallelism and reduce the convergence time. Our simulation results reveal that ARB-DGSI-FEM significantly improves the parallelism without too much sacrifice of accuracy.

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.

MANET is a decentralized network optimized for an infrastructure-less area. Its applications are designed to operate in a distributed manner. Peer-to-peer (P2P) overlays are a possible addition to MANETs to aid in managing resources and information sharing in distributed networks. In this paper, the Kademlia P2P overlay is deployed over a dynamic and different MANET underlaying technologies. This overlay was combined with two different types of MANET routing: OLSR and AODV. An extensive evaluation is carried out for the performance of these combinations in different dynamic network settings. The results show that in most cases, Kademlia achieves its best performance when layered over AODV. However, OLSR-based Kademlia outperforms AODV in terms of delay and network load.

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.

Mobile network edge computing is an excellent technology to reduce service latency to users by extending services of existing central cloud computing to network edge. But the service provided to the user in the user space is not a service provided simply by reducing the delay time. The user space service provides a user's preferred spatial environment and automatically and promptly provides the user with preferred contents. So, the user space service is necessary to provide user space service platform infrastructure for automatically and promptly providing a user with a preferred spatial environment and contents. Therefore, this paper proposes a user space customized recommendation service platform system that can provide users with enhanced quality of service using shortened service delay time in mobile edge environment.

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).
