Abstract: A control system for controlling a network including a plurality of network apparatuses, includes a network site controller for controlling a cooling system in the network and extracting network resource and ambient information from the plurality of network apparatuses into topological information, and a network controller for controlling the plurality of network apparatuses based on the topological information.

Abstract: Systems and methods are disclosed herein for multicasting a data packet through a wireless network. The method includes a packet metadata which maintains a set of next-hop nodes on the routing path as well as the assigned destination nodes of the packet. In addition, each node maintains only a single self-rooted forwarding tree for determining the routing path. By using the metadata in conjunction with a single forwarding tree at each node, the method introduces a highly scalable alternative to multicast protocols based on link state routing source-based trees while substantially reducing the processor load. Furthermore, the method does not require a consistent view of the network topology, making it useful in mobile scenarios. Also included is a mechanism to minimize the packet metadata size for minimal impact to performance while supporting arbitrarily large multicast group sizes.

Abstract: This invention relates to systems and methods for communication in a wireless ad hoc network that employs multi-packet reception. The wireless network includes a transmitting node configured to transmit a control packet to a receiving node while other nodes within a transmission range of the transmitting node are involved in ongoing communication. The receiving node is configured to receive the control packet while simultaneously receiving a second packet from a second transmitting node, and to process the control packet without aborting the receiving of the second packet. Methods for transmitting and receiving multiple packets simultaneously are also presented.

Abstract: A method (508) and system (226) provide directional medium access control for wireless nodes (102) in a wireless network (100), each of the nodes (102) having a transceiver (228) and a plurality of antennas (232, 234, 236, 238, 240) in selective communication with the transceiver (228). Packets (202) are transmitted from a transmitting node (106) of the nodes (102) when a channel (104) is sensed as being free in a beam direction of a selected one of the antennas (232, 234, 236, 238, 240), and in accordance with a pre-determined transmission mode (304) for the data packet (202). The transmitting node (106) is periodically placed in a forced idle state, thereby being prevented from transmitting data packets (202), but being able to receive and respond to data packets (202) from other nodes (102).
