Aiming at the current situation of hydrological monitoring, integrating with the application of internet of things in hydrological monitoring area, to realize automation of hydrological monitoring, the system for hydrologie monitoring based on internet of things is designed. This system is constructed with internet of things technology, software technology, evaluated network technology, etc. The system...
According to characteristics of coal mine goaf, a suitable routing mechanism based on LEACH protocol was proposed. The mechanism's improvement including two sides: Firstly, LEACH cluster heads selection mechanism was improved. Secondly a routing algorithm of wireless sensor network was designed with the multi-path routing mechanism. Finally, the NS2 simulation result show that this new routing mechanism...
For some existing power consumption modes in wireless ad hoc networks, corresponding methods or principles for solving the problems have been put forward. This paper briefly introduces some representative methods for reducing power consumption in ad hoc networks and gives an evaluation for each method. Basing on different typical protocols, more progressive protocols are elaborated. Eventually, this...
In this paper, we proposed a centralized SIP-based Video Conference System. The function structure of the system was designed and the implementation method was introduced. The proposed Video Conference System can meet to the needs of the application in small medium enterprises, and it can provide higher conference quality with a lower cost.
