    摘要: When a source node (SN) seeks to transmit a first communication stream (FCS) to a destination node (DN), a method is provided for allowing the SN to preempt a lower priority communication stream (LPCS). User priorities are supported during slot scheduling based on stream-identifiers (IDs) and stream priority values exchanged by each of the nodes. A scout request message (SRM), which includes a stream ID and a user priority value of the SN, is transmitted to a next-hop node along a route towards the DN. A node along the route determines if free time slots are available along the route to meet QoS requirements of the FCS, and if not, the node determines whether there is a LPCS in the neighborhood, and if so, the node frees the particular time slots currently being used by the LPCS, and allocates the particular time slots for the FCS.

    摘要: A method provides for differentiating usage permissions between different categories of communication traffic within a given network. The method includes ensuring one or more categories of traffic never transits communication radios, link, and/or spectrums dedicated to a different category of traffic. A combined routing metric is calculated using a scaling factor for discouraging usage of restricted communication links and encouraging usage of non-restricted communication links.

    摘要: In a network comprising a source, a destination, and intermediate nodes along a route between the source and the destination, techniques are provided for allocating one or more time slots to transmit a particular data stream along the route based on the QoS requirements to transmit the particular data stream. In one implementation, a Scout Request message (SRM) is sent from the source to the destination to allocate time slots along the route to transmit a particular data stream to the destination. The SRM can include QoS requirements to transmit the particular data stream. Each intermediate node along the route can allocate one or more time slots to transmit the particular data stream based on the QoS requirements needed to transmit the particular data stream along the route.

    摘要: A system and method for characterizing the quality of a link, in particular, a bi-directional link, between nodes in a wireless communication network, such as a wireless ad-hoc peer-to-peer network, with minimum network overhead. The system and method determine the quality of link between two nodes by taking into consideration the view from both the nodes, and factors such as signal strength, signal-to-noise ratio or any statistic collected at the physical layer that is deemed representative of the quality of a link. The link quality can also be adjusted using a weighting factor.

    摘要: A system and method for decreasing the route convergence time in a wireless communication network, such as a wireless ad-hoc peer-to-peer network, by finding an alternate route if the nodes anticipate weakening or breakage of a route currently in use. The system and method which enables reactive routing protocols to find optimal routes between nodes in these types of networks when those routes cannot otherwise be found in certain conditions. The system and method thus decrease the route convergence time, provide an effective and efficient way to find optimal routes, and improve overall performance of the network with regard to throughput, delay, packet completion rate and other factors.
