摘要:
Methods and systems of the present invention are directed to clustering RFID-tag readers of a multi-RFID-tag-reader network in order to obtain a set of RFID-tag readers with high probability of detecting an event, but with low probability of collisions and with an acceptable cost. The cost may be determined by any of numerous cost functions of the RFID-tag readers in the set of RFID-tag readers, and may represent a cost in power, long-term reliability, and other such metrics that may be applied to an RFID-tag network.

Methods and systems of the present invention employ perturbation techniques for configuring RFID-tag-reader networks in order to achieve increased overall efficiency of a network of RFID-tag readers. According to described embodiments of the present invention, individual RFID-tag readers within a multi-RFID-tag-reader network may be removed or shut down, or RFID-tag readers may be displaced relative to one another, in order to remove interferences between RFID-tag readers and to increase the interrogation efficiency of the multi-RFID-tag-reader network.
摘要:
The present invention includes a method and system for dynamically controlling cooling resources in a data center based on the workload of the data center. Accordingly, based on the workload constraints (power consumed, latency, etc.) of the data center, each of a plurality of different types of cooling resources is activated in an optimal fashion. Consequently, a substantial savings in operational costs related to cooling resources is achieved. A first aspect of the present invention is a method for dynamically controlling cooling resources in a data center. The method comprises determining a workload within the data center, determining an amount of heat being generated as a function of the workload and activating each of a plurality of different types of cooling resources within the data center in an optimal fashion based on the amount of heat being generated.
