In next generation wireless networks along with the overwhelming demand of high data rate and network capacity, the user demands ubiquitous connectivity with the network. In order to fulfill the demand of anywhere at any time data services, the network operators have to install more and more base stations that eventually leads towards high power consumption. For this, the potential solution is derived...
This paper highlights, neural network (NN) based adaptive control using backstepping control technique is proposed for robot manipulator trajectory tracking. Firstly, the vector of current is considered as the control variable for robot manipulator mechanical subsystem by using the adaptive update algorithm of NN and an enclosed control input for the desired vector of current is constructed. So that,...
Nowadays, the wireless devices are equipped with multiple network interfaces to support different wireless technologies, for example, Universal Mobile Telecommunications System (UMTS), Wireless Local Area Network (WLAN), and Bluetooth etc. However, while increasing the options to connect internet via different access networks, seamless mobility cannot be assured when the wireless device is roaming...
To provide seamless internet connectivity anywhere at any time to the mobile users, there is a strong demand for the integration of wireless access networks for all-IP based Next Generation Networks (NGNs). The major limitation of UMTS networks is that they do not efficiently serve indoor, small and densely populated areas, i.e., hotspots. On the other hand, such hotspots where bandwidth intensive...
Currently, there is a need to provide communication services at anytime, anywhere with the low cost and the best quality. Moreover, deployment of WLAN network aiming to offer services in a hot-spot region, such as airports, hotels, railway stations, etc. tend towards the need to provide the integrated architecture of UMTS and WLAN. The integration of UMTS and WLAN is beneficial for both user and service...
To provide service anywhere and at anytime, there is a strong demand for integration of two promising technologies; UMTS and WLAN. By integrating these two, the user can have the benefits of using both technologies. The WLAN is capable of providing high data rate at low cost. However, its services are limited to a small geographical area. UMTS networks coverage area is wider, however, cost is high...
