In this paper, we present an approach to managing resources in a large-scale heterogeneous wireless network that supports reconfigurable devices. The system under study embodies internetworking concepts requiring independent wireless networks to cooperate in order to provide a unified network to users. We propose a multi-attribute scheduling algorithm(More)
The proliferation of wireless broadband usage over the last decade has led to the development and deployment of multiple broadband wireless radio access technologies (RATs) such as EVDO, WiMAX, HSPA and LTE. To support the ever-increasing wireless traffic demand, researchers have worked on the concept of an integrated heterogeneous wireless environment that(More)
Energy Management for multi-mode Software Defined Radio (SDR) systems remains a daunting challenge. In this paper, we focus on the issue of task allocation for multi-processor based systems with hybrid processing resources that can be reconfigured. With the objective of minimizing energy, we propose a fast, energy aware static task mapping heuristic to(More)
As broadband data further blends with cellular voice, mobile devices will become the dominant portals to the connected world. However current design practices still involve building independent networks that each make their own resource decisions. In spite of the tremendous amount of related research in this area, there are still several elemental questions(More)
Aggressive voltage overscaling (VOS) has been recently adopted to reduce the power consumption of embedded memories. While this affects reliability, several techniques have been developed to achieve reliable operation under aggressive VOS. In this paper, we present a comprehensive power-performance study of LDPC decoders enabling aggressive VOS to internal(More)
Energy management for multimode software defined radio systems remains a daunting challenge. This brief develops a high level framework that generates a multiprocessor systems on chip architecture from a library of heterogeneous processing resources that can be reconfigured to support various modes of operation. The framework proposes joint task and core(More)
The design of efficient multiprocessor systems on chip (MPSoC) is a daunting challenge. This challenge is driven by the increasing demand in achieving high performance, low power, and reconfigurable applications onto the same platform. As a consequence, there is an emerging need for fast, and efficient design space exploration, while providing abstract(More)
