This work presents two-rank (Wi-Fi and LTE) analytical model, from which we can evaluate the goodput of vehicular wireless network depending on the number of vehicles N in the access point (AP) coverage area. To evaluate the suitability of the model used, experimental data are compared with the theoretically calculated data. The results obtained allow us to evaluate the performance of each individual...
Combining Wi-Fi and LTE data transmission technologies we can obtain an integrated solution that provides full end-to-end data transmission channel. This article compares goodputs of two LTE routers, which connect multiple WLAN access points (including Wi-Fi access controller) with the remote FTP server. Handover impact on data channel goodput is measured between wireless access points. Experimental...
The main goal of the paper is to develop models for designing WLAN, used in transport networks with mobile objects‥ In this paper were considered two modes of movement traffic. In the first mode was considered the open model with an unlimited number of transport. In this mode is considered the highway with the different number of bands and with Erlang distribution of traffic flow. In the second mode...
The article introduces an integrated network and traffic simulation platform called Opnet (Optimized Network Engineering Tool). This platform provides the capabilities of network simulation and network protocol simulation. In this paper, we simulate two layer network models with WiFi and WiMAX scenarios and compared their throughput and load HTTP and FTP protocols. Evaluating the performance of these...
Vehicular communication is a popular topic in the academia and the car industry. The aim of these growing interest is to develop an effective communication system for the Intelligent Transportation System (ITS). In this paper we presented the model of wireless base station good put evaluation. We used wireless access point model as a queuing system with variable requests and the auto traffic model...
Vehicle-to-infrastructure (V2I) communication based on wireless local area network (WLAN) technology can support highly mobile users to obtain Internet connectivity. Wireless access for the vehicular environment (i.e. IEEE802.11p) provides the required principal standardization for vehicle-to-vehicle V2V solution and supported raw data rate up to 27 Mbps. This standard mainly is oriented on urgent...
