|20140185454||Effective Bandwidth Path Metric and Path Computation Method for Wireless Mesh Networks with Wired Links - Enhanced mesh network performance is provided by computation of a path metric with respect to multi-hop paths between nodes in a mesh network and determination of a path through the mesh network that is optimal according to the path metric. Information is communicated in the mesh network according to the determined path. Nodes in the mesh network are enabled to communicate via one or more wireless links and/or one or more wired links. The path metric optionally includes an effective bandwidth path metric having elements (listed from highest to lowest conceptual priority) including an inverse of a sustainable data rate, a number of wireless links, and a number of wireless and wired links. The sustainable data rate is a measure of communication bandwidth that is deliverable by a path for a period of time. Accounting is made for interference between contiguous wireless links operating on the same channel.||07-03-2014|
|20130329582||Mesh Node Mobility Across Static and Mobile Mesh Networks - Methods and systems for mobility of mobile nodes in mesh networks are taught wherein the mobile mesh nodes choose an attachment point to another mesh node based on predetermined criteria, such as the characteristics of the attachment point's path to a reference destination, and other factors local to the attachment point, such as load and available capacity. The mobile nodes forward packets on each other's behalf. Static and mobile nodes and the links between them are treated differently from each other in view of their respectively different properties. A special metric is used for paths that include mobile links in addition to the static mesh links and wired mesh links. Mobility is handled completely transparently to any client devices attached to the mesh nodes, where this attachment could be wireless or wired.||12-12-2013|
|20110051677||CHANNEL ASSIGNMENT FOR WIRELESS ACCESS NETWORKS - Channel assignment for wireless access networks is directed toward improved overall communication capability of the networks. A network is formed of wireless access points (APs) coupled via wired (and/or wireless) links and enabled to communicate with clients via radio channels of each of the APs. Local information is collected at each of the APs and processed to determine channel assignments according to a Neighbor Impact Metric (NIM) that accounts for one-hop and two-hop neighbors as well as neighbors not part of the network. Optionally, the NIM accounts for traffic load on the APs. The channel assignments are determined either on a centralized resource (such as a server or one of the APs) or via a distributed scheme across the APs. The local information includes how busy a channel is and local operating conditions such as error rate and interference levels.||03-03-2011|
|20100296494||SERVICE DIFFERENTIATION AND SERVICE LEVEL AGREEMENTS FOR WIRELESS ACCESS CLIENTS - Differentiated services are provided through service level agreements (SLAs) between access nodes and some of the clients using a wireless access network. Client devices include internal devices that are compliant with service-related specifi-cations published by the access nodes. Client devices also may include non-compliant external and legacy devices, as well as out-side interferers. The access nodes control target SLAs for each client device. The access nodes and the internal client devices per-form rate limiting to ensure that a device's target SLA is adhered to. The service-related specifications include schedules to ensure preferential access for preferred internal client devices. The internal client devices send usage and bandwidth availability feedback to the access node they are associated with, enabling the access node to come up with better schedules for meeting the preferred internal devices' SLAs in view of the network conditions reported via the feedback.||11-25-2010|
