Industrial Wireless communications is emerging technology after the Fieldbus in industrial field. For industrial control application with wireless industrial technologies, the WIA-PA standard defines the protocol suite, system management, gateway, and security for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting the limited power consumption requirements. In...
Modern wireless networks, such as WiMAX or LTE are using OFDM/OFDMA as the enabling technologies for broadband transmission in cellular environments with QoS capabilities. In these networks, such schema as radio resource management, admission control, scheduling are essential. In this article we firstly introduce a Time-Frequency Burst Mapping algorithm for radio resource management that improves...
One of major objectives of the 4G wireless network architecture is to facilitate seamless mobility of users between heterogeneous networks while satisfying QoS requirements. The moment at which a user should switch from the current network to another where better resources can be provided is still a hot research topic. This work studies a new criterion for triggering the vertical handoff process....
We consider the network with two kinds of traffic: inelastic and elastic traffic. The inelastic traffic requires fixed throughput, high priority while the elastic traffic has controllable rate and low priority. Giving the fixed rate of inelastic traffic, how to inject the elastic traffic into the network to achieve the maximum utility of elastic traffic is solved in this paper. The Lagrangian Duality...
