A Study on the ZigBee Wireless Communication for IAQ Monitoring of Underground Subway Stations ijtsrd
In this paper, the 424MHz ZigBee module, which uses a relatively lower frequency for wireless transmission and reception, is found to have a much higher data transfer rate than that of the 2.4GHz XBee PRO in the presence of obstacles such as subway waiting rooms, platform like stairs, complicated structures, and crowded passengers. This indicates […]
Design and Evaluation of MAC Protocol Strategies Techniques in Wireless Ad Hoc Network IJTSRD
Wireless communication has become a core part of modern communication technology. The Infrastructure less wireless network, commonly referred to as Ad Hoc networks, has attracted extensive research interest for past 30 years. In this work, the focus is on IEEE 802.11 network performance analysis of Multihop hop Ad Hoc networks under non-saturated network conditions. To […]
MAC: Protocols for Cognitive Radio Sensor Networks and their Comparision IJTSRD
Wireless Sensor Networks (WSNs) deliver smart communication paradigm which can set up intelligent networks handling all the applications as per the user requirements. The WSNs offer several advantages like flexibility, fault tolerance, low cost and easy deployment. Typically, a WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions. These sensors generate […]
Occupancy-based Surveillance with Wireless Camera Network for Public Safety: Creating Safe Places with Internet of Things to Live in Urban IJTSRD
The monitoring of public areas with video cameras is becoming increasingly important due to the security concern around the world. Real-time surveillance of people and their activities in urban environments is becoming increasingly important in the context of public safety. The advance of wireless technologies has expanded the scope and capabilities of camera networks, which […]
