Design, Implementation and Evaluation of.. - Kounavis, Campbell, .. (2000) (Correct)
....Programmable networks [4] separate the communications hardware from the control software, allowing the modeling of hardware resources using open programmable interfaces. In this manner third party software providers can enter the market for telecommunications software. Work on software radios [6, 7] has shown that wireless physical layers can be created dynamically by introducing code into programmable base stations with wide band tunable front ends. In this paper, we focus on the control plane and address the problem of making handoff programmable for the introduction of new services. We ....
....present the implementation and evaluation of our architecture, respectively, focusing on the deployment of the multi handoff and reflective handoff services. In Section 6, we provide some concluding remarks. 2. Related Work Programmable mobile networks represent an emerging area of research. In [6, 7, 14, 15] the programmability of the physical layer is addressed based on digital signal processing techniques and wide band analog to digital conversion. Software radios allow access points and mobile devices to implement physical layer functionality (e.g. modulation, equalization, channel coding) in ....

....in processor speed and memory size while maintaining outstanding price performance. Several years ago it became possible to implement an FM radio receiver in software on a general purpose PC, with all processing stages in software except for initial amplification and downconversion to baseband [1]. Subsequent work has resulted in software implementations of a variety of RF protocols. The commodity marketplace has also seen the recent introduction of low cost products with significant bandwidth improvements compared to previous PC standards: RAMBUS memory systems (2x memory bandwidth) ....
....is structured as a library of C objects, each of which performs a dedicated function such as filtering or demodulation. The objects are instantiated at run time and connected together into data processing pipelines, in which data is pulled by the sinks rather than pushed by the sources. See [1] for a description of an earlier system that inspired the current software architecture. The library contains objects which application writers can use to splice together pipelines on separate machines into a single distributed pipeline. Data is sent over the network as a TCP stream. In the 100 ....

An Architecture for Adaptable Wireless Networks - Rao (2000) (Correct)
....thesis presents the design, implementation, and analysis of a Controller Module that facilitates adaptation in the physical layer of wireless devices. The benefits of an adaptable physical layer are demonstrated for a voice compression application. The Controller Module is part of the SpectrumWare [1] architecture, a software based approach to designing communication systems. The SpectrumWare approach to signal processing enables a system designer to build flexible and adaptable wireless devices. This level of flexibility is achieved by using software in place of specialized hardware ....

Using the Module Array, each object can be identified through its index in the array. 2.6.2 Registration After the Controller module has been instantiated, it registers with each of the physical layer modules. STACK CONTROLLER REGISTER CHANGE PARAMETERS STATUS 19 Module Array[1] register(Controller Module) Module Array[2] register(Controller Module) Since the Controller Module registers with each of the physical layer modules, the module designer does not need to know the name of the Controller Module that may use it. The Controller Module does not make use of the ....
