Implementation of MSK Modulation Scheme for Zigbee System / IEEE 802.15.4 Physical Layer IJTSRD
In this work physical layer simulation of IEEE 802.15.4 / ZigBee protocol has been done. The proposed work is the implementation of ZigBee system according to the protocol description. In this work we have simulated ZigBee system first with conventional OQPSK modulation technique, then the simulations are performed for MSK modulation, which is through OQPSK […]
Literature Survey on ZigBee / IEEE 802.15.4 System Implementation IJTSRD
ZigBee is a low-cost, low-power consumption, wireless mesh networking standard. Firstly, the low cost allows the technology to be widely deployed in wireless control and monitoring applications. Secondly, the low power-usage allows longer life with smaller batteries. Thirdly, the mesh networking provides high reliability and more wide range. ZigBee is a standard which defines a […]
A Study on “Radar Helmet for Soldiers” IJTSRD
Soldiers are very essential part of any nation’s security system. During, wars and search operations soldiers get injured and some of them go missing. As we all know soldier’s health is important because they are the savior of our country who protects us from terrorist attacks and from many suspicious activities which can harm us […]
Smart Grid Communication Protocols IJTSRD
Present power grids are getting replaced by smart grids, mainly for improving performance of existing power grid. Integration of electrical, electronics and computer science have led this technology more popular. Smart grid technology is characterized by full duplex communication, automatic metering infrastructure, renewable energy integration, distribution automation and complete monitoring and control of entire power […]
Database System in Automatic Billing for Supermarket IJTSRD
Now-a-day shopping in city-mark and mall is increasing rapidly. While shopping, customers have to face some difficulties. First, they go at the billing counter for payments their total expenditure but there are many people standing in queue for billing purpose. This is unnecessary waste time for customer because cashier scans each item bought with barcode. […]
