Performance Analysis of Genetic Zone Routing Protocol Combined With Vertical Handover Algorithm for 3G-WiFi Offload

In the deployment scenario of multiple base stations there is usually a deficiency in the routing protocols for load balancing in the wireless network. In this study, we propose a routing algorithm that can be implemented inMobile Adhoc Networks (MANETs) as well as third-generation (3G)"“Wireless Fidelity (WiFi) offload networks. We combined the Genetic Zone Routing Protocol (GZRP) with the Vertical Handover (VHO) algorithm in a 3G"“WiFioffload network with multiple base stations. Simulationresults show thatthe proposed algorithm yields improvement in the received signal strength(which is increased up to 25 dBm), user throughput (which is approximately 1 Mbps-2.5 Mbps), and data rate (which is increased up to 2.5 Mbps)

Ship Speed Estimation using Wireless Sensor Networks: Three and Five Sensors Formulation

Intrusion detection on the sea is an important surveillance problem for harbor protection, border security, and commercial facilities such as oil platforms, fisheries facilities and other marine wealth. Widely used methods for ship detection are using radar or satellite which is very expensive. Besides the high cost, the satellite image is easy affected by the cloud. And it is difficult to detect small boats or ships on the sea with marine radar due to the noise or clutters generated by the uneven sea surface. In this paper, we propose ship speed estimation by taking advantage of ship-generated wave’s characteristics with Wireless Sensor Network (WSN). We use a grid fashion for sensor node deployment that can be clustered into three and five sensors. We propose the ship speed formulation for each type of claster. We use three sensors, we may expect to improve energy efficiency by involving small number of sensor for detection. We use five sensors, we may expect to improve accuracy of detection. We also propose an algorithm for detection by incorporating individual sensor detection. The individual sensor detection produces a time stamp that records the ship-generated waves intruding the sensors

The Future of Nanotechnology and Quantum Dots for the Treatment of COVID-19

Today, drugs and vaccines for treating coronavirus disease 2019 (COVID-19) are being developed in Russia, China, the USA, Canada, Turkey, Germany, the UK, and Indonesia. Not all drugs for treating COVID-19 have the same functions or target the same aspects of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), the cause of COVID-19. Very recently, some vaccines have been reported to effectively protect against COVID-19. Clinical vaccine trials are in phase 3 in several countries, including Indonesia, Turkey, Chile and Brazil. A virus is an intracellular parasite with a very simple structure. Viruses lack their own metabolism and thus require a host to replicate. That is why washing one’s hands with soap is the first step in preventing the spread of viruses with a lipid membrane, such as SARS-CoV-2. Soap effectively destroys such viruses because they are self-assembled structures. However, soap cannot be used to destroy the virus within a host because the same process that destroys the virus also destroys human cells. At the moment, much research in the area of nanotechnology is ongoing. Quantum dots (QDs) have been incorporated in many nanotechnological treatments, including drug delivery, bioimaging of cancer cells, and cancer diagnosis and treatment. Many researchers are investigating the use of new materials to treat COVID-19; possible therapies employ modified graphenes and QDs, among others. QDs are multifunctional crystalline semiconductors on a nanometer scale. Based on our studies, this QDs has fewer coordinating molecules on the surface. Nanometer-sized QDs are thermodynamically unstable but can be kept in a colloidal form to maintain stability. Due to their unique optical properties, QDs have significant potential for biomedical applications, including biomedical imaging, biosensors, drug delivery, clinical diagnosis, photodynamic therapy, DNA hybridization, and RNA profiling. Very recently, the potential of QDs for targeting virus cells has received attention. This function could be used to inhibit the activity of COVID-19. The use of QDs to treat COVID-19 still needs more evaluation and investigation. QDscan be functioned and coated with other molecules to improve their drug delivery profile. The chemical functionality of the surface of a QD can also be controlled by a capping agent such as Schiff base compound, which provides colloidal stability, prevents agglomeration and uncontrolled growth, increases solubility, and extends the exciton lifetime of QDs.The development of QDs and of nanostructured semiconductor crystals (which are usually under 10 nm in size) has opened new horizons in nanoscience and nanotechnology. QDs have been used in a wide range of applications in various fields, including biochemistry, physical chemistry, biomedicine, medicine, pharmaceuticals, microscopy, and engineering. QDs are also a powerful imaging probe for diagnostics and prognostics.     The development and manufacture of bioengineering and medical equipment and devices has become more efficient, and computational modelling and simulations are now used to gather insights into new products.&nbsp
