Abstract: An electricity load management device and an electricity load management method thereof are provided. The electricity load management device is connected to a plurality of data centers via a network. Each of the data centers comprises at least one server. For each data center, the electricity load management device allocates a plurality of data allocation percents of a plurality of service requests sequentially according to a schedule so as to receive a piece of electricity consumption information from each data center. The electricity load management device creates a cost profile of each data center according to the electricity consumption information of each data center, and determines an electricity load allocation percent of each data center according to the cost profiles and the electricity charge information. Finally, the electricity load management device allocates the subsequent service requests to the data centers according to the electricity load allocation percents.

Abstract: A method for assigning wireless network transmission resource includes the following steps: at least one contention area is broadcasted. A join message is uplinked to a base station (BS) by at least one client utilizing the contention area. Determine if the join message received by the BS has been interfered with. If the join message received by the BS has not been interfered with, the contention area is assigned to the client. The client utilizes the contention area to upload data.

Abstract: A bandwidth reservation system and method for dynamic channel switching, and a computer readable recording medium are provided. The bandwidth reservation system includes a transmitting terminal, for selecting a first channel from a plurality of channels to establish a connection, and detecting the other channels and selecting a second channel for switching and then establishing a new connection for data transmission, when the first channel does not have sufficient bandwidth for reservation; a receiving terminal, for establishing the connection with the transmitting terminal and receiving the data transmitted from the transmitting terminal, and switching to the second channel according to the requirement of the transmitting terminal, so as to establish the connection and to perform the data transmission.

Abstract: A memory management method and a memory architecture for transmitting ultra-wideband (UWB) prioritized channel access (PCA) frames are provided. The method comprises the steps of assigning a pre-load queue to each of a plurality of access categories for storing UWB PCA frames to be transmitted, and, when one of the access categories gains transmission opportunity (TXOP), assigning a common area queue to that access category for storing UWB PCA frames to be transmitted. Moreover, when a UWB PCA frame in one of the pre-load queues reaches a predetermined size, the access category corresponding to the pre-load queue starts its backoff state machine in order to gain the TXOP.
