Influence of Thermal Radiation on MHD Casson Nanofluid Flow over a Non-Linear Stretching Sheet with the Presence of Chemical Reaction

The focus of this research is to examine how the Casson and chemical reaction parameter impact the variable radiative flow of MHD Nanofluid across a stretching sheet. Through the use of similarity functions, the modelling equations (PDEs) of the motion of fluid are transformed into simple differential equations. The MATLAB tool is adopted to compute the equations numerically. Graphs and descriptions have been provided for velocity, concentration, and temperature outlines, showing the effects of important fluid flow constraints. Different factors are analysed to provide data and explanations for Prandtl, Lewis numbers, slip and chemical decomposition parameters. The current results are in good in good align with existed reports. The viscosity of the fluid and thermal boundary stratum decreases as enhancing of Casson, Magnetic parameter & Prandtl number. Skin friction increasing as enhancing of suction, stretching, magnetic and Casson parameter while decreasing as enhancing of velocity slip quantity. Rate of heat transmission enhancing as increment of thermal radiation and surface temperature while decreasing as enhancing chemical reaction and thermal slip quantities. Rate of mass transfer raising as enhancing of chemical reaction, thermal slip, thermal radiation while decreasing as enhancing of surface temperature parameter

Optimization of IPv6 Neighbor Discovery Protocol

In IPv6, the DAD (Duplicate Address Detection) protocol detects duplicate addresses configured on the local link. Once the IPv6 address is auto configured on an IPv6 enabled host, the host verifies that its address is unique using the DAD procedure. This protocol works when hosts can communicate. If the DAD protocol fails to detect duplication, both the hosts assign the same link-local address. The neighbor discovery protocol verifies the generated address is unique or already exists on the local link. This process is known as Duplicate Address Detection (DAD). This process has critical security vulnerability and is susceptible to many attacks, especially allowing hackers to perform denial of service attacks (DOS). With that, the new devices will not be able to join the network. Researchers have developed various techniques to address DAD vulnerabilities, such as NDPMon, SEND, and Software-defined networking, SAVA, and extension headers. These techniques appear to be neither robust nor performance-oriented with DAD’s DOS detection and mitigation techniques. We have proposed a novel approach that detects and mitigates DOS attacks consuming low bandwidth and overhead. </jats:p
