    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: The invention relates to the design of power sequences for use in a group of sub-areas of a wireless communication system. Each power sequence defines for one of the sub-areas transmission power values for transmissions using a respective one of a plurality of medium access units. For each of the sub-areas of the group, reception quality values are determined for transmissions between an access station serving the sub-area and mobile stations located at an edge of the sub-area. The reception quality values allow meeting system. The reception quality values are then converted for each of the sub-areas into transmission power values of a power sequence.
