    摘要： A method includes identifying a white space at a first wireless node and selecting a channel in the identified white space. The white space includes at least one frequency or frequency band not in use (like a licensed frequency or frequency band). The method also includes identifying at the first wireless node a channel access factor for each of multiple wireless nodes including the first wireless node. The method further includes determining if the first wireless node has a specified channel access factor. In addition, the method includes transmitting data from the first wireless node on the channel when the first wireless node has the specified channel access factor. The channel access factors can be identified and the determination whether the first wireless node has the specified channel access factor can be performed without using control signals transmitted between the wireless nodes. The channel access factor could represent a hash function value.

    摘要： A network system for inter-component communications in an electronic device is disclosed. The system comprises a plurality of components for an electronic device, where each of the components communicates with at least one other component over a communications medium for a wireless mesh network. Each of the components comprises a communications transceiver operable to determine network traffic load levels for an exchange of communication data between the components, and allocate the network traffic between at least one pair of the components over a plurality of wireless links within the wireless mesh network based on potential-field based measurements at each of the components. In addition, each of the communications transceivers share the exchange of the communication data between the components based on a prescribed priority level for allocation of the network traffic.

    摘要： The present invention provides a method for providing message transmission in H.323 communication system. The method includes: the first endpoint and second endpoint confirming authentication information through a GK; according to said authentication information, the first endpoint and second endpoint exchanging message directly. Since H.235 protocol of ITU-T describes the authentication and privacy technique used in H.323 systems and provides security service for message transmission in GK-routed model, the present invention can guarantee the security of the authentication information. The functions of middle entities need not to be modified for applying the method provided by the present invention because Diffie-Hellman key exchange technology is adopted in this method. The present invention increases the network scalability of the symmetric key system by adopting negotiation mode. The present invention designates and improves the security framework of message transmission in direct-routed model of H.323 system, thereby improving the security of H.323 system.
