In this paper, the performance of an expanded controller level (1-out-of-3) fault-tolerant Wireless Networked Control System is studied. The system is composed of three identical workcells with zero meter inter-cell separation and is based on the unmodified IEEE 802.11b Wi-Fi standard. The control system is shown to satisfy certain packet end-to-end delay deadline with no loss of control packets....
A novel analytical framework of multiple radio access technologies (Multi-RAT) communication system is proposed where a small cell serves K mobile users via IEEE 802.11 Wireless Local Area Network (WLAN) and 3GPP Long Term Evolution (LTE) access technologies. A scheduler at the small cell is proposed in order to minimize the total transmission power subject to quality of service constraints on the...
Heterogeneous Networks (HetNet), particularly Femto cells, were introduced to meet the exigent need for higher network capacity. Although Femto cells increased the network capacity, they increased the interference to the Macro Indoor users.In order to avoid the high decrease in cell edge throughput different interference mitigation techniques were introduced like Inter-Cell Interference Coordination...
Heterogeneous Networks (HetNets) comprising of Macro and Femto stations are very promising to increase indoor coverage and throughput of the future cellular networks. In this paper, we characterize the interference environment of the Femto HetNets based on the Femto dual strip deployment model. We show that the Macro Indoor subscribers or User Equipments (UEs), who are not associated with Femto stations...
This paper considers Down-Link (DL) Coordinated Multi-Point (CoMP) transmission/reception techniques within Heterogeneous Networks (HetNets) which are comprised of Macro Stations (MSs) and Pico Stations (PSs). CoMP schemes based on Joint Processing/Joint Transmission (JP/JT) and transmit Zero Forcing (ZF) algorithms are evaluated using a static System-Level Simulator (SLS). Performance comparisons...
The current WiMAX operators have to choose whether to utilize reuse-1 (R-1) or reuse-3 (R-3) frequency planning pattern. The R-1 pattern achieves high spectral efficiency but results in high inter-cell interference(ICI), especially at the cell-edge users. As for the R-3, it reduces the ICI and guarantees coverage to the cell-edge users. However, the R-3 pattern still achieves low cell-edge user throughput...
