Design and Construction of GSM Based Fire Alarm System using PIC Microcontroller ijtsrd
A fire alarm system is used our properties safe form fire. It can be designed in many ways in different components. Many expensive building must have their fire alarm systems. In market almost systems are indoor systems. The indoor systems can be known only the person who inside the building. So, this paper focus on […]
Energy Harvesting Alternatives for Powering Critical WSN Based and Autonomous Monitoring Systems ijtsrd
Wireless Sensor Network WSN applications in the industry, domestic and commercial sectors are becoming quite interesting and exciting. For instance, since January 2005, major International Oil and Gas companies IOCs operating in Nigeria Niger Delta region have made wireless sensor network the defacto monitoring system for their vast oil and gas pipelines, oil wells and […]
Analysis and Comparison of Different Spectrum Sensing Technique for WLAN ijtsrd
This Paper explores basic two systems of spectrum sensing Cooperative System and Non Cooperative System. Non Cooperative System includes Energy detector, Match Filter and cyclostationary with a performance analysis of transmitter based detection. It also includes analysis of Match Filter and Cyclostationary under low and high SNR, validating the result and applied the technique for […]
Design and Implementation of A VHF Tri Loop Antenna for 2 Meter Amateur Band ijtsrd
This paper presents the design and implementation of a triangular loop antenna using aluminum tubing of diameter 10mm with high electrical conductivity and reflecting ability. The antenna operates in very high frequency VHF band covering a frequency range of 140 to 150MHz. It has a gain of 3 dB and a radius of coverage of […]
Classroom Shared Whiteboard System using Multicast Protocol ijtsrd
Multiple hosts wish to receive the same data from one or more senders. Multicast routing defines extensions to IP routers to support broadcasting data in IP networks. Multicast data is sent and received at a multicast address which defines a group. Data is sent and received in multicast groups via routing trees from sender s […]
