    摘要: Message authentication in an ad-hoc network. Upon creation of a message, a message authentication code is created using a key shared with members of a group comprising a subset of nodes of the ad-hoc network. The message authentication code may be created using a cryptographic process having the message and a message identifier as inputs. After or in parallel with broadcast of the message, a pointer to the message is broadcast. The message authentication code is publicly broadcast and those members of the group among which the key has been shared are able to authenticate the message as coming from a particular sender.

    摘要: An approach is provided for using pseudonyms to protect privacy and anonymity of communication messages. A pseudonym is extracted from a received message for comparison against a precomputed set of pseudonyms associated respectively with a plurality of communities of wireless nodes. The pseudonyms are valid only for a particular time period.

    摘要: A system for facilitating communal apparatus interaction. In accordance with at least one embodiment of the present invention, an apparatus configured to communicate on a wireless channel may receive first information pertaining to wireless traffic expected from other networks also utilizing the wireless channel. The apparatus may then determine whether the received information satisfies a first criterion, and if it is determined that the first information satisfies the first criterion, the apparatus may shorten an awake window duration for communicating on the wireless channel. Alternatively, if it is determined that the information does not satisfy the first criterion, the apparatus may proceed to further determine whether second information pertaining to wireless traffic on the wireless channel that is expected from a network satisfies a second criterion. If it is determined that the second information satisfies the second criterion, the apparatus may proceed to lengthen the awake window duration.
