Global Optimization of Transmitter Placement in Wireless Communication Systems

چکیده
This paper explores the application of a global optimization technique to solve the optimal transmitter placement problem in wireless system design. An efficient pattern search algorithm—DIRECT (DIviding RECTangles) of Jones, Perttunen, and Stuckman (1993)—has been connected to a parallel 3D radio propagation ray tracing modeler running on a 200-node Beowulf cluster of workstations. The algorithm optimizes, for a given computational investment, the locations of a specified number of transmitters across the feasible region of the design space. The focus of the paper is on the implementations of the DIRECT algorithm and the parallel 3D ray tracing propagation model. Both simulation results and site measurement data are presented in support of the effectiveness of the present work.

Global Optimization of Transmitter Placement for Indoor Wireless Communication Systems
The DIRECT (DIviding RECTangles) algorithm [23], a variant of Lipschitzian methods for bound constrained global optimization, has been applied to the optimal transmitter placement for indoor wireless systems. Power coverage and BER (bit error rate) are considered as two criteria for optimizing locations of a specified number of transmitters across the feasible region of the design space. The pe...

متن کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملQuasi Random Deployment Strategy for Reliable Communication Backbones in Wireless Sensor Networks
Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...
متن کاملDesign of a novel congestion-aware communication mechanism for wireless NoC architecture in multicore systems
Hybrid Wireless Network-on-Chip (WNoC) architecture is emerged as a scalable communication structure to mitigate the deficits of traditional NOC architecture for the future Multi-core systems. The hybrid WNoC architecture provides energy efficient, high data rate and flexible communications for NoC architectures. In these architectures, each wireless router is shared by a set of processing core...
