Design and Performance Analysis of DSS (Dual Sink Based Scheme) Protocol for WBASNs

引用

Advances in Remote Sensing 2017年第4期6卷 245-259页

作者： Abdul Ahad Saud Al Faisal Farzand Ali Bahlool Jan niamat ullah Department of Computer Science Virtual University of Lahore Lahore Pakistan Department of Electronics Engineering Comsats University Islamabad Pakistan Department of Computer Science Preston University Islamabad Pakistan Department of Computer Science University of Swat Swat Pakistan Department of Computer Science Abdul Wali Khan University Mardan Pakistan

After a large improvement in health care services, Wireless Body Area Sensor Network (WBASN) is used in different fields where health care monitoring can be done continuously and from a distance. Many selected protocols are given in literature work which can improve the performance of WBASN by focusing on delay, routing and energy efficiency. In our research, we will focus on improving throughput, network life time, and decrease end-to-delay. In given research, the two sink nodes utilized and AnyCasting concept will be used. Dual Sinks based Scheme (DSS) for WBASN will be compared with existing DARE, SIMPLE, LAEEBA and M-ATTEMPT protocols. DSS performance found more efficient than DARE, SIMPLE, LAEEBA and M-ATTEMPT respectively in throughput. From results, DSS network life time is greater than DARE, SIMPLE, LAEEBA and M-ATTEMPT with minimum delay. In DSS, energy parameter is in tradeoff with the improved parameters, because of a computation of RSSI which do more process and utilize more energy.

Bianchi Type-V Cosmological Models for Perfect Fluid with Time-Varying Gravitational and Cosmological Constant

引用

Journal of Applied Mathematics and Physics 2017年第11期5卷 2283-2290页

作者： Mohammed Aman ullah Mohammad Amjad hossain Mohammad Moksud Alam Department of Mathematics University of Chittagong Chittagong Bangladesh

Einstein’s field equations with variable gravitational and cosmological constants are considered in presence of perfect fluid for locally-rotationally-symmetric (LRS) Bianchi type-V space-time discussion in context of the particle creation. We present new shear free solutions for both absence and presence of particle creation. The solution describes the particle and entropy generation in the anisotropic cosmological models. We observe that time variation of gravitational and cosmological constant is needed for particle creation phenomena. Moreover, we obtained the particle production rate Γ(t) for this model and discussed in detail.

Vehicle Fuel Activities Monitoring System Using IoT

引用

Advances in Internet of Things 2019年第4期9卷 63-71页

作者： Rasheda Khatun Sabbir Ahmed Antor Ahsan ullah Afzal hossain Department of Computer Science and Engineering World University of Bangladesh Dhaka Bangladesh

IoT is extensively used in everyday object and its popularity is increasing day by day. In this paper it includes the design and development of an IoT and mobile-based vehicle fuel activities such as real time fuel monitoring and GPS tracking system. The proposed IoT device measures the amount of fuel by using ultrasonic fuel sensor. When the vehicle tank of fuel reaches a certain level, driver gets notification through mobile application and also searches the nearest pump location for reloading fuel. The proposed system used GPS tracking for showing current location of vehicle and finding nearest pump location.

Cost Effective Smart Hydroponic Monitoring and Controlling System Using IoT

引用

Intelligent Control and Automation 2019年第4期10卷 142-154页

作者： Ahsan ullah Sadia Aktar Nipa Sutar Rafsan Kabir Afzal hossain Department of Computer Science and Engineering World University of Bangladesh Dhaka Bangladesh

Hydroponic System is a system in which farmers cultivate different plants without utilizing the soil. The authors have proposed IoT system that monitors and controls all parameters of hydroponic system like water level, pH, humidity and temperature through mobile application. In proposed system, the authors have used an ESP32 micro-controller that is controlled pump. The pump will draw water from a reservoir which is connected to a regular water line. If the water level of the reservoir falls down to a certain level, the system will send an SMS to the Farmer. The farmer can control the water line and make the reservoir full by mobile application. An LDR and DHT11 humidity sensor is used to control the light and temperature of the farm. In system, we also used pH sensor where pH sensor is a scientific instrument that measures the hydrogen-ion activity in water-based solutions and indicating its acidity or alkalinity expressed as pH.

Advances in Internet of Things 2019年第4期9卷 72-84页

作者： Ahsan ullah Mohammad Anwar hossain Nusrat Zaman Mampy Dey Tanwy Kundu Department of Computer Science and Engineering World University of Bangladesh Dhaka Bangladesh

IoT can aid alliance of communication, monitor and information processing across various transportation systems. The authors have developed a real time public bus management system based on IoT and android application. The authors have used GPS (Global Positioning System) to track the nearest location of the bus and police station;IR sensor is used for checking seat availability. The authors also use a Panic Alert Button on every seat of the bus to reduce women harassment. With the press of the panic alert button, the notification sends to the owner and the nearest police station with the current location of the bus.

Journal of Information Security 2019年第4期10卷 199-236页

作者： Mohammad Anwar hossain Ahsan ullah Newaz Ibrahim Khan Md Feroz Alam Department of Computer Science and Engineering World University of Bangladesh Dhaka Bangladesh

Cloud computing is a kind of computing that depends on shared figuring assets instead of having nearby servers or individual gadgets to deal with applications. Technology is moving to the cloud more and more. It’s not just a trend, the shift away from ancient package models to package as service has steadily gained momentum over the last ten years. Looking forward, the following decade of cloud computing guarantees significantly more approaches to work from anyplace, utilizing cell phones. Cloud computing focused on better performances, better scalability and resource consumption but it also has some security issue with the data stored in it. The proposed algorithm intents to come with some solutions that will reduce the security threats and ensure far better security to the data stored in cloud.
