The purpose of this study is twofold. First, this study proposes a cost-effective LoRa gateway to improve bandwidth utilisation to achieve optimal network throughput for LoRa networks from a hardware design perspective. Secondly, this study creates a design for adaptive and autonomous algorithm to allocate bandwidth while meeting dynamic throughput...
Free to read on publisher website The emerging mobility management schemes for the fifth generation (5G) of mobile networks mostly follow the network-based protocol principles, which do not involve the mobile node (MN) in their operation. Such solutions have not been able to meet the ultra-low handover latency requirement in complex mobility scenar...
The concept of Trust has been applied in many information systems such as e-commerce, social networks and smart grid networks. It is currently getting attention on the Internet of Things. The fundamental concept in Trust, is the ability of a user to evaluate its neighbour, or a recommended neighbour with the hope of being able to trust that user. I...
In this paper, wireless 802.11ac client-server network with open system (no security) and WPA2 (Wi-Fi Protected Access 2) security is investigated. The results shows that, by implementing WPA2 security, TCP throughput of IPv4 and IPv6 on average decreased by 16.79% and 10.22% respectively. Throughput for UDP is decreased by 18.07% and 12.99% for IP...
In this paper, the performance of VoIP on IPv4, IPv6 and 6in4 protocol with and without IPsec is compared. RTT (Round Trip Time), Throughput, Jitter and CPU usage are compared in VoIP networks. The results for throughput are almost same for both operating systems. CPU usage was higher on both operating systems with IPsec enabled and the results for...
In this paper, we improve throughput performance of a cognitive radio network through a proposed dual-level sensing strategy. Throughput performance of secondary users cannot be enhanced while providing higher priority to protect primary users from secondary user interference. Therefore, we propose a novel multiple access scheme based on dual-level...
Urban public spaces are increasingly sutured with a range of surveillance and sensor technologies claiming to enable new forms of “data based citizen participation,” but often leading to “function-creep,” whereby vast amounts of data are gathered, stored, and analysed in a broad application of urban surveillance. This kind of monitoring and capacit...
IPSec (IP Security) and SSL (Secure Socket Layer) are the main technologies for securing communications via the Internet. In this paper, we present new results on the performance of SSL using Windows 7 operating system under IEEE802.11n wireless network. Enabling IPSec security results on average approximately 50% less TCP throughout while enabling...
This paper presents a survey of current energy efficient technologies that could drive the IoT revolution while examining critical areas for energy improvements in IoT sensor nodes. The paper reviews improvements in emerging energy techniques which promise to revolutionize the IoT landscape. Moreover, the current work also studies the sources of en...
An alternative learning approach for destructive testing of structural specimens in civil engineering is explored by using a remote laboratory experimentation method. The remote laboratory approach focuses on overcoming the constraints in the hands-on experimentation without compromising the understanding of the students on the concepts and mechani...
