Application of the Internet of Things Technology in the Urban Ecological Protection and Environmental Rehabilitation With the continuous development of cities, the urban water pollution has become more and more serious, and the urban water pollution has become an important factor restricting the further development of cities. Nowadays, the water ecological environment of many cities in China has been affected and destroyed to varying degrees. Protecting the water ecological environment and reducing the damage to the water ecological environment has become an urgent problem. The relevant departments and the relevant personnel should continue to study and explore, in order to find ways to mitigate the damage to the water ecological environment and to repair the damaged water ecological environment while the urban economy continues to develop. This paper focuses on the analysis of the characteristics and connotation of the Internet of Things technology, and combines the background of the application of this technology in the urban ecological protection and environmental restoration, so as to explore the application strategy of the Internet of Things technology in the urban ecological protection and environmental restoration.

IoT Application in River Monitoring: Methods and Challenges Water pollution is a major threat both locally and globally to the sustainability of clean water. In Malaysia, river is a major source of water. Industry output, chemicals from agriculture sectors and constructions, sewage and water waste make sustainability of clean water a big challenge. Hence, the need for continuous and effective monitoring of river in order to maintain the water quality (WQ) of river. The existing methods of river water quality monitoring in Malaysia are Manual Water Quality Monitoring (MWQM) and Continuous Water Quality Monitoring (CWQM). These methods are nonreal time, less effective, inaccuracy of data collection and also costly to be implemented. The use of internet of things (IoT) for realtime monitoring and analysis of water quality in rivers in Malaysia. Also has becoming famous these days because it provides solution to the consumer cover from shortrange communication until long range communication technology. The aim of these paper is to identify different method for river monitoring and discuss the challenges of these methods so that more effective solution can be produce.
