  • Patent number: 7813373
    Abstract: 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.

    Abstract: An ad hoc network includes a first node, a second node, and a third node. The first node and second node share a first shared secret key, and the first node and third node share a second shared secret key. The second node and third node share a temporal key. The first node generates a unique key, encrypts the unique key with a first shared secret key to generate a first encrypted unique key and transmits the first encrypted unique key to the second node. The first node encrypts the unique key with a second shared secret key to generate a second encrypted unique key and transmits the second encrypted unique key to the third node. To establish the temporal key, the second node decrypts the first encrypted unique key and the third node decrypts the second encrypted unique key thereby each generating the unique key.
