Abstract: A distributed multi-channel TDMA MAC time slot and channel allocation algorithm for wireless networks is provided. The time slot and channel allocation includes a distributed allocation phase and an allocation adjustment phase. Each phase begins allocation at a first node and continues node-by-node until the last node in the network. The allocation then reflects back from the last node to the first node. At each node in the path, the node can initiate resource allocation between itself and its neighbor nodes. Nodes that are within range of the wireless network but are not on the path do not initiate resource allocation but instead participate in the resource allocation initiated from other nodes.

Abstract: Systems and methods for providing a boundary scan test of a wired or wireless network having a plurality of network nodes are presented. The system includes a test station communicatively coupled with the network. The test station creates a MAC layer scan test route sequence that includes each link in the network and is independent of the routing mechanism and protocol used for the network. The test station also creates a test agent that is configured to traverse each link in the scan test route sequence. The test agent is then deployed on the network and information about a link is reported back to the test station after the test agent examines the link. The scan test route sequence can be created by sending out a series of broadcast messages from one or more nodes in the network, sequentially applying a network tour to cover the entire network, or performing a depth first search on the entire network.

Abstract: A scalable medium access control (“MAC”) module is provided that avoids conflict resource reservation so that network performance does not degrade as the number of hops or nodes in a wireless network increases. The MAC also provides different access schemes for traffic with different quality of service (“QoS”) requirements such that QoS is guaranteed and network resources are efficiently utilized. Furthermore, the resource allocation scheme determines the routing path as resources is allocated for data traffice, thereby achieving more robust layer-2 routing at the MAC layer. Finally, the scalable MAC is compliant with both WiMedia MAC and IEEE 802.15.3 MAC.

Abstract: Systems and methods are provided that facilitate distributed multichannel wireless communication and provide the highest level quality of service (“QoS”) guarantee and support extremely high bandwidth applications such as voice over internet protocol (“VOIP”) streaming audio and video content (including high definition), and multicast applications and also supports convergent networks, ad hoc networks, and the like. A modular MAC architecture provides a group of nodes with the ability to simultaneously communicate with each other using multiple separate communication channels during the same timeslots. The additional throughput gained by employing multiple communication channels is amplified by dynamically mapping the communication channels and timeslots in a network so that multiple channels can be reused simultaneously throughout the network during the same timeslot in a fashion that does not create collisions.

Abstract: A wireless communication system is provided that has at least three nodes arranged in a multi-hop ultra wide band (UWB) communication network such that communications from a first node destined for a third node pass through a second node. Each of the devices in the system includes a radio and a media access control (“MAC”) module that is configured to establish multi-hop UWB wireless communications between the three or more wireless communication devices that enables high bandwidth applications such as Voice Over Internet Protocol (“VoIP”); multiplayer gaming; Wireless High Definition Television; and Internet Protocol Television (“IPTV”) among others. The MAC module is configured to avoid bandwidth reservation conflicts so that network performance does not degrade as the number of hops or the number of nodes in the wireless communication system increases. The MAC also facilitates utilization of multiple channels to maximize the available spectrum and is further configured to dynamically switch between channels to maximize throughput and meet or exceed quality of service (“QoS”) requirements such that QoS is guaranteed and network resources are efficiently utilized.

Abstract: Systems and methods for transparent wireless bridging of communication channels are provided. A plurality of wireless bridge devices are each deployed on a wired communication channel segment and listen for traffic to build a table of MAC addresses for the network devices on each respective segment. The bridges also collectively form a wireless mesh network and publish the MAC addresses on the wireless mesh network so each bridge receives MAC address information for every segment. Accordingly, a sending device on a first segment sends a communication to a target device on a second segment. The respective first bridge passes the communication along through the wireless mesh network to the respective second bridge and the first bridge also sends an acknowledgement to the sending device on behalf of the target device. This proxy acknowledgement allows the wireless bridge system to account for potential latency over the wireless mesh network while at the same time complying with latency requirements and meeting or exceeding the overall round-trip time for network communications.

Abstract: A system and method for routing packets over wireless and wired networks is presented. The system employs an attribute routing scheme that routes communication packets that include objects containing network optimization parameters that are used to control the physical links in the network. The routing transport protocol is logically separated from the objects that are routed, which allows objects having new optimization parameters beyond the conventional network topology parameters or network link parameters to be defined and propagated throughout the network. Additionally, new dynamic routing objects of arbitrary size can be defined that have a customizable update period. These dynamic routing objects are propagated through the network based on their respective custom update periods. The system also includes a feature that enables exponential backoff in the custom update periods. Updates may also be linked to one another, enabling network clients to query the network for related information resulting in efficient implementation of a networking system.
