Abstract: Delay Tolerant Networks enable data transmission in different applications, mainly in environments where communication infrastructure is missing. The existence of links is casual and even when links are created, they are short in time and unstable/unreliable in terms of connectivity. Thus, underwater network applications tend to be delay tolerant. In this paper, we propose a mobility-aware routing protocol for underwater wireless sensor networks. The protocol is based on Focused Beam Routing (FBR) protocol and considers nodes’ next destination location when making forwarding decisions. The routing protocol is called Destination-aware Focused Beam Routing (D-FBR) protocol and we compare its performance with …FBR protocol for different FBR angles and different applications. We use Delivery Probability (DP), Average Number of Hops (ANH), Overhead Ratio (OR) and simulate our scenarios by The ONE simulator. Simulation results show that, for D-FBR protocol, when FBR angle is 30 ∘ , OR and ANH is improved by 34.5 % and 23.1 % , respectively, while DP is 6.5 % lower, compared to FBR protocol. Both D-FBR and FBR outperform Epidemic Routing Protocol. Show more

Abstract: In this paper, the application example of 8 × 100 Gbit/s over 463 km (76.9 dB) optical transport network is realized by using commercial bidirectional Raman amplifier and additional auxiliary laser without any remotely pump amplifier. The positions of the auxiliary laser in the commercial Raman amplifier are compared and optimized experimentally. The results show that 7.3 dB and 10.2 dB more power budget is obtained with the auxiliary laser in the backward direction and forward direction respectively comparing to the situation without any auxiliary laser. The results also show that forward second order Raman amplifier is a good choice in the condition without remotely pump …amplifier. Show more

Abstract: Wireless Body Area Network (WBAN) is a promising solution that has gained significant attraction in the human health monitoring system. Body sensors measure the physiological parameters of the human body and send the data to the access point via coordinator or local processing unit (e.g., smartphones, PDA) for further analysis. Data transmission from the local processing unit to the access point, known as inter-WBAN transmission, is challenging since many problems such as interference, poor link quality, and scarcity of resources can arise. As a result, data may be lost, or transmission may be delayed, which turn can endanger the user’s …health. The situation could be worse when the user suffers from critical diseases and has to coordinate with other WBANs co-located in the same vicinity. This paper focuses on dynamic slot scheduling and topology handling of WBAN, whose neighborhood is constantly changing due to its mobility. To guarantee the performance of different WBAN’s criticality; we propose Critically Aware Threshold Sensitive (CATS) scheduling algorithm for coexisting WBANs data transmission. CATS treats all the nodes in the same WBAN as a whole and allocates the same slot to nodes of the WBAN so that the data transmission delay of a critical WBAN can be minimized. The proposed method categories and schedules the WBANs based on the sensor data priority and WBAN’s criticality index. Furthermore, we have considered for categorizing the WBANs into various groups. In this work, the network performance is evaluated using these threshold values. Simulations are conducted to evaluate the performance of the proposed CATS against the existing scheduling algorithms with respect to various performance metrics. Simulation results show that the proposed method has lower transmission delay and higher spatial reuse factor. Show more

Abstract: The Software-Defined Network (SDN) with Network Slicing will be a good approach for admission control in the Fifth Generation (5G) wireless network, which is planned to be adaptable to meet user requirements. The system’s resources are limited, and the number of devices is growing much faster than it can handle. So, the overloading problem will be a very critical problem. To deal with these problems, this paper presents a Fuzzy-based Scheme for Service Level Agreement (SLA) evaluation (FSSLA). We compare two models: FSSLA1 and FSSLA2. The FSSLA1 considers three input parameters: Reliability (Re), Availability (Av), Latency (La) and the output …parameter is SLA. In FSSLA2, we consider Traffic Load (Tl) as a new parameter. From simulation results, we conclude that the considered parameters have different effects on the SLA. When Re and Av are increasing, the SLA parameter is increased but when La and Tl are increasing, the SLA parameter is decreased. When the Tl value is changed from 20% to 80%, the SLA is decreased by 16.62% when Re 10%, Av 90% and the La value is 1 ms. When the Re is increased from 10% to 90% and 50% to 90% and the Tl value is 50%, the Av is 50% and the La is 1 ms, the SLA is increased by 22.76% and 11.38%, respectively. Show more

Abstract: The purpose of this paper is to help college students improve their physical health and build a sound health management system. The physical exercise and health management of college students following IoT (Internet of Things) are studied. First, the current situation of college students’ physical quality is analyzed, and it is found that the college students’ physical quality and mental states decline in recent years. Second, the connotation of health management is briefly introduced and its necessity is analyzed. Health management cannot only improve the physical condition of students but also cultivate students’ strong will. Then, the application and characteristics …of IoT are described, and the framework of physical exercise is designed based on IoT. Finally, a questionnaire survey is designed, and the survey results are compared and analyzed. According to the statistical results of the intervention group and the control group before and after the intervention, it is found that physical exercise has a significant effect on improving the physical and mental states of college students. The average scores of each dimension of physical states after the intervention are higher than those before the intervention, and the scores of each symptom in mental illnesses are lower than those before the intervention. This shows that the main method of health management based on physical exercise has a very obvious positive effect, which helps college students to improve their physical and mental states and cultivate their good habit of taking exercise.

Abstract: Due to the mobility and frequent topology changes, routing the data poses a challenging issue in the Internet of Things (IoT). Security poses a fundamental requirement factor in most IoT applications particularly, secure routing among the IoT nodes. The aim of this paper is to develop secure routing in IoT with minimal delay, minimal energy consumption and high throughput. Thus, a new algorithm, named Rider Foraging Optimization algorithm (RFO) is designed by the incorporation of standard Rider Optimization algorithm (ROA) and Bacterial Foraging optimization algorithm (BFO) that render an optimal solution, which is the optimal path for transmitting the information. …Initially, the trust of the nodes is evaluated and the cluster head (CH) is chosen based on Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol to securely transmit the data. Then, the proposed RFO algorithm selects the optimal path using the fitness factors, such as trust, energy, and delay constraints. The results revealed that the energy consumption of the nodes is reduced and the lifetime of the network is enhanced through the implementation of the proposed RFO, which attained a maximal throughput of 1, and minimal delay and energy consumption of 0.1169 and 0.0002, respectively.
