Internet of Things (IoT) is a new technological revolution which brings many advantages to its users. However, IoT devices and sensor nodes in Wireless Sensor Networks (WSNs) have limited resources, such as energy, memory, computational speed, and communication bandwidth. Thus, better utilization of energy is necessary to avoid problems like high energy consumption and low network lifetime. This paper presents the most well-known and current methods for energy efficiency in both WSNs and the expandable IoT. In addition, a novel low-energy approach for maximizing energy efficiency in IoT, called Energy Efficient Scheme for IoT (EES4IoT), is proposed. This scheme merges efficiently two other schemes for energy efficiency, network lifetime enhancement, maintenance cost reduction and shortest path finding for data transmission. The new proposed scheme demonstrates energy savings in the sensor nodes and extending lifetime of WSNs.

Instead of arrayed -waveguide grating (AWG) coder/decoders approach, we aim at intelligent coding computations to mitigate interference noises from noises-accumulated multi-carriers transmissions. Recursive interference cancellation result will be worse off if there is strong noise in the transmission channel. An interference cancellation method based on convolutional neural network (CNN) was proposed to the increased or cancel noise to improve accuracy of retrieving optical target data signals in multiuser systems. In this paper, we focus on the training gathering, and analysis. The training data for CNN model building was discussed with different decision rules. The performance of CNN-based interference cancellation method was defined according to the analysis result of training data collection. The analysis result shows that if we can retrieve the estimation noise which approach the true noise, the better BER will be acquired.

Information-Centric Networking (ICN) is attracting attention as a content distribution method against increasing network traffic. ICN router has the cache function. However, when a large amount of the interest packets for the same content that is not present in the cache occurs during a short time, there is a problem of redundant interest packet, and data packet flows to the upstream link. Such contents expect to happen in case of social affairs, like featured sports. To solve this problem, we propose a method that the server pushes the predicted content to the neighboring nodes before a large amount of interest to the content will occur. As the simulation results, it is confirmed that the possibility of reduction for the number of packets flowing in the upstream link and the number of routing table states required for push distribution.

With the rapid increase of internet capacity, the transmission capacity of optical fiber communication systems is approaching to the nonlinear Shannon limit of single-mode fiber. Recently, mode division multiplexing (MDM) technology is widely studied due to its ability to increase the communication capacity. Mode multiplexing/demultiplexing is one of the key technologies for implementing MDM. A variety of mode multiplexing/demultiplexing solutions have been reported, such as phase plate structure, spatial light modulator (SLM) structure, multi-core fiber structure, photonic lantern, mode-selective coupler, silicon-based mode multiplexer. In this paper, the basic principles of those solutions and the relevant latest experimental results are discussed and reviewed.

As the world continues to push boundaries, so as the capabilities of technology. Through wireless innovations and infrastructures, people have never been as connected as before. This study rides on with these innovations specifically in the frontier of TV White Space through developing and implementing a Geolocation Database on the basis of the ITUR P.1411 recommended propagation models. Propagation models are the core of a Geolocation Database and ITU-R P.1411 was used to suit short-range outdoor communications in the 300MHz to 100GHz frequency range such as the IEEE 802.11af standard. The keep-out distance calculated from the ITU-R P.1411 recommendation along with the licensed TV channel’s service contour was used to estimate the TVWS in the province of Cebu, Philippines. The developed Geolocation Database was able to estimate about 30 MHz of available licensed TV channels mostly located in the northern and southern ends of the Cebu province. It was also successfully implemented with the IEEE 802.11af system.

Android applications combined with Bluetooth technology are an inseparable pair at this time especially for controlling a robot. A sophisticated military robot is a robot that is needed by the military/police because it can be deployed to the battlefield or the eradication of terrorism that can be controlled remotely. This system is needed to reduce the remaining casualties from the army, and this combat robot system can also be operated at any time with more numbers than regular soldiers and with minimal operator needs. In this paper, we propose a prototype of a tank-based military robot with object detection and tracking and controlling using Android for simulation of shooting the enemy target. We propose an algorithm for controlling the robot using an HC-05 Bluetooth module. The methods explained, and experimental results were presented.

When we employ wireless communications in a factory, its channel state can change dynamically due to factory-specific propagation environments. Therefore, it is difficult to realize a stable communication link with common unicast transmissions. In order to realize stable communications in such an environment, in this paper, we focus on broadcast transmissions, where a sender transmits a packet to multiple access points (APs). With broadcast transmissions, even if an AP is not able to receive data because of bad channel conditions, the other APs may receive it, which can contribute to the realization of robust data transmissions. However, link reliability of broadcast transmissions is inherently low due to the absence of ACK and retransmission mechanisms. In order to solve this problem, in this paper, we apply packet-level FEC to broadcast transmissions. With computer simulations and actual indoor experiments, we investigate the effectiveness of broadcast transmissions exploiting multiple AP receptions with packet-level FEC.
