    摘要: A method for establishing a secure route in a wireless network as provided improves network efficiency. According to one aspect, the method includes receiving at a first node in the wireless network a route request message from a second node, where the second node and the first node have not been mutually authenticated. The route request message is then forwarded from the first node to a third node. A route reply message is then received at the first node from the third node. The first node is then mutually authenticated with the second node in response to receiving the route reply message at the first node.

    摘要: Techniques are provided for selecting a root node in an ad hoc network that contains a plurality of nodes including a first node. According to one implementation of these techniques, a first node can receive a message from at least one of the other nodes. Each message includes a number of primary factors associated with a particular node regarding capabilities of the particular node. The primary factors associated with each node can then be evaluated, and an attempt can be made to select the root node based on the primary factors associated with each node. If the first node is unable to select the root node based on the primary factors associated with each node, then the root node can be selected based on secondary factors associated with each node.

    摘要: A method for merging of ad hoc network partitions within an ad hoc network, the method includes forming a plurality of network partitions by forming a security association among each of a group of partitioned nodes. Each network partition includes a Network Identifier. A node operating within one of the network partitions receives an update message from another node, compares its current Network Identifier to the received Network Identifier; and determines whether to update to the received Network Identifier using an arbitration method when the received Network Identifier is different from the current Network Identifier.

    摘要: A method for providing reliable multicasting is described. A transmitted multicast packet is received at second devices, each of which in response transmits a first acknowledgement. If a second acknowledgement, which acknowledges the first acknowledgement, is not received within a predetermined time period, the first acknowledgement is retransmitted. If all first acknowledgements are not received within a preset time period, the multicast packet is retransmitted. If the retransmitted multicast packet has been received, at each of the second devices, if the second acknowledgement has not been received the first acknowledgement is retransmitted, while if the second acknowledgement has been received, the retransmitted multicast packet is ignored and no additional first acknowledgement is transmitted.

    摘要: Method and apparatus for packet scheduling in a wireless network is described. First values for a data transmission rate are measured for each of a plurality of mobile stations over time. Second values for a function of the data transmission rate are computed using at least one of the first values for each of the mobile stations. A rate of change of the data transmission rate is computed for each of the plurality of mobile stations using the second values associated therewith. A stability of the data transmission rate is computed for each of the plurality of mobile stations using the second values associated therewith. A channel quality factor is determined for each of the mobile stations using a current value of the second values, the rate of change of the function, and the stability of the function associated therewith.

    摘要: A self-learning geographically aware handoff method and system is disclosed. The system includes a handoff manager (108), which receives information about a position and movement of the mobile nodes (102a, 102b, 102c and 102d) present in the mobile network (100). The handoff manager learns the coverage capabilities of the access points (104a, 104b, 104c and 104d) in the mobile network. It then determines a second access point, to which a mobile node will handoff to, based on the learned coverage capabilities. The handoff manager then informs the mobile node about the second access point.
