The framework needs to track the states of the computing resources for being able to take advantage of the reconfiguration capabilities of mobile terminals and network elements. An SDR processing chain, SDR application or waveform, is the part of an SDR transceiver that is implemented in software. It can be understood as a set of concurrent processes that continuously process and propagate real-time data. Such a processing chain is not specifically tailored but rather executable on any general-purpose platform with sufficient computing capacity. Therefore, an automatic mapping process needs to dynamically assign software modules to hardware resources, while meeting all computing system constraints. Our computing resource management framework is modular. It features the computing system modeling on the one hand and the computing resource management on the other (Figure 1). The SDR computing system modeling captures the SDR platforms' computing resources and the SDR applications' computing requirements. We, therefore, suggest equivalent metrics for modeling computing resources and requirements: million operations per second (MOPS) and mega-bits per second (Mbps) for modelling the processing and interprocessor data flow capacities and requirements. The ALOE computing resource management is based on two simple time management principles: time slots and pipelining (Figure 2). This facilitates the synchronized execution of the waveform modules on distributed computing resources while taking advantage of the continuous data flow that characterizes wireless communications. Based on these principles, ALOE applies a general-purpose mapping algorithm, the ''tw''-mapping, and a problem-specific cost function. The cost function implements the computing resource management objective or policy while guiding the allocation of computing resources to computing requirements in a controlled manner. The ''tw''-mapping and more details about the ALOE computing resource management approach can be found in the attached document.
