“…They are likewise conceivable between various innovations; recognized as perpendicular handovers whilst the previous are recognized as level handovers. It was an advanced characterized designate conveyed inside one innovation while the first is the conveyance between various/numerous strategies [26]. There can be diverse purposes behind conveyances that happen, and here are a couple of reasons: at the edge of the screen, the quality of the flag is not enough to sustain the correspondence.…”

The concepts of quick base station switching are just like MDHO; the MS and BS would be the same ability to support the quick base station switching.…”

Recently, data traffic movement through a wireless channel is assisted by suggesting and implementing many mechanisms, to achieve the speedy increasing importunity and popularity of the wireless networks. Various wireless technologies can be copulated to develop a heterogeneous network, which is a candidate towards (4G) networks. OPNET modeler (14.5) is used to design simulation modules of the heterogeneous network. During device connection between the worldwide interoperability for microwave access (WiMAX) and universal mobile telecommunication system (UMTS) networks, Performance metrics such as; Jitter end-to-end delay (E-2-E) Throughput is used. The results of the simulation are measured to determine the efficiency of the transfer using WiMAX-UMTS according to the selected metrics. The WiMAX-UMTS has shown valuable improvement in Process Durability, reduction of E-2-E delay, and Jitter. The maximum amount of data transfer and the least amount of delay and Jitter is at 250 sec. Because of the handover operations and data transfer momentum, the worst-case passes in the network when 618 sec is the minimum amount. The efficiency of throughput for WiMAX equal to 0.092666% as for the efficiency of throughput for UMTS equal to 4.633333*10 -6 % whereas the E-2-E efficiency a delay equal to 0.5466%.

“…This protocol is being adopted widely and used extensively by most big companies such as Amazon and Facebook to exchange data between resource-constrained devices. MQTT supports publish/subscribe architecture [9] over TCP [10] protocol. It has two components that are the client as a publisher or subscriber and the broker.…”

Security is one of the main concerns with regard to the Internet of Things (IoT) networks. Since most IoT devices are restricted in resource and power consumption, it is not easy to implement robust security mechanisms. There are different methods to secure network communications; however, they are not applicable to IoT devices. In addition, most authentication methods use certificates in which signing and verifying certificates need more computation and power. The main objective of this paper is to propose a lightweight authentication and encryption mechanism for IoT constrained devices. This mechanism uses ECDHE-PSK which is the Transport Layer Security (TLS) authentication algorithm over Message Queuing Telemetry Transport (MQTT) Protocol. This authentication algorithm provides a Perfect Forward Secrecy (PFS) feature that makes an improvement in security. It is the first time that this TLS authentication algorithm is implemented and evaluated over the MQTT protocol for IoT devices. To evaluate resource consumption of the proposed security mechanism, it was compared with the default security mechanism of the MQTT protocol and the ECDHE-ECDSA that is a certificate-based authentication algorithm. They were evaluated in terms of CPU utilization, execution time, bandwidth, and power consumption. The results show that the proposed security mechanism outperforms the ECDHE-ECDSA in all tests.

“…They found UDP has preferable performance than TCP for video streaming. The authors of [8] configured TCP and UDP as an underlying protocol for exchange of data between two wireless mobile nodes in a WiMax access network and had evaluated the effect on performance in terms of end-to-end delay and throughput. The results showed that when handover is triggered the transfer window resets to zero causing higher throughput and end-to-end delay for TCP than UDP.…”

Worldwide Interoperability for Microwave Access (WiMAX) is a Metropolitan Area Network (MAN) wireless technology that provides broadband Internet access to both fixed and mobile users. Due to limited radio propagation range of wireless mobile devices and variable and unpredictable characteristics of wireless communication medium, there are certainly some effects of the speed of mobiles, and the amount of reliability provided by the underlying Transport Layer on the network performance. In this study, simulation of WiMAX networks is performed using Network Simulator 2 (NS2) to investigate the effects of Maximum Velocity and Pause Time of Mobile Stations and a comparative performance analysis of two commonly used Transport Layer Protocols, namely, Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), is also conducted. TCP variant New Reno is used. For more realistic simulation, NS2 scene generation script is modified. Experiments demonstrate that performance of a WiMAX network is relatively stable when TCP is used. TCP shows overall better performance, especially in case of Packet Delivery Ratio and Average End to End Delay, while throughputs are almost similar for both the protocols, which prefers the use of TCP over UDP in mobile WiMAX networks for all applications.
