DESIGN AND IMPLEMENTATION OF MOBILE IPTV SYSTEM FOR WIRELESS NETWORKS

In recent years, the ZigBee network has been rapid develop in smart home. In order to solve the intercommunication barrier in heterogeneous wireless networks in the smart home, a wireless home gateway which is based on embedded is designed and implemented in this paper. The gateway is made up of the main controller S3C2440, the ZigBee module JN5148 and the Wi-Fi module VT6656. It is capable of converting Wi-Fi protocol data or ZigBee protocol data, transmitting them to each other and integration of heterogeneous wireless networks. This paper describes the design and implementation process of the gateway hardware and software, introduces the Wi-Fi protocol data and the ZigBee protocol data conversion approach, and resolve the bottleneck caused by the two protocol different transmission rates. Then the performance of the gateway is tested, and the results indicate the Wi-FiZigBee gateway is completely meeting the needs of the smart home.

Residential Electricity

Nowadays, the development, implementation and deployment of smart meters (SMs) is increasing in importance, and its expansion is exponential. The use of SMs in electrical engineering covers a multitude of applications ranging from real-time monitoring to the study of load profiles in homes. The use of wireless technologies has helped this development. Various problems arise in the implementation of SMs, such as coverage, locations without Internet access, etc. LoRa (long range) technology has great coverage and equipment with low power consumption that allows the installation of SMs in all types of locations, including those without Internet access. The objective of this research is to create an SM network under the LoRa specification that solves the problems presented by other wireless networks. For this purpose, a gateway for residential electricity metering networks using LoRa (GREMNL) and an electrical variable measuring device for households using LoRa (EVMDHL) have been created, which allow the development of SM networks with large coverage and low consumption.
