Localization of sensor nodes in WSN in many different scenarios is becoming an important issue due to their widespread application. Different system parameters are changed in order to have a better performance. In this study are taken in consideration the simulation of the approaches of Hybrid algorithm but now with two more improvements brought to it. Based on simulations we understood the influence...
Recent researches on the usage of technology in different area of life activities have made WSN widely useful in monitoring different environments. Different monitoring tasks are being used in WSN and for that; in order to acquire the best performance is needed to focus in an essential parameter that is the node localization. This paper studies the localization issue based on three existing algorithms,...
Nowadays, wireless services are becoming increasingly present in our daily lives. UMTS technology is successfully implemented and is already installed everywhere. Wi-Fi service should be tested to coexist with UMTS service, with minimal interference. Hence in typical domestic environments is verified the possibility of coexistence of two antennas, in the same access space. Initially, the characteristic...
