A wireless network [includes a number of first wireless terminals configured to operate as cluster heads [by communicating with at least one other cluster head over a relatively long range backbone link [. Each one of the first wireless terminals includes a backbone transceiver. The backbone transceivers may operate in a first frequency range. At least one second wireless terminal is configured to operate as a cluster member [by communicating with an associated cluster head over a local link. Each one of the second wireless terminals includes a cluster transceiver. The cluster transceivers may operate in a second frequency range that is different from the first frequency range of the backbone transceivers. At least one of the first and second wireless terminals includes both a backbone transceiver and a cluster transceiver.

Method and apparatus for detecting whether router status information sent from a first router is unreliable, includes structure and/or steps for storing a router status database. Structure and/or steps are provided for receiving a first signal corresponding to a first router status message sent by the first router, the first router status message containing router status information indicative of the status of communication between the first router and a second router. Further, structure and/or steps are provided for issuing an alarm signal if the signal comparison reveals that the first and second router status messages contain non-complementary router status information. Such information can be flooded through the network to isolate the unreliable/compromised router.

A system archives encryption keys used for encrypting information in a network (). The system includes a plurality of nodes configured to collect one or more encryption keys generated at each node and to transmit the one or more collected encryption keys to a key archive () for storage in a database associated with the key archive (). The key archive () is configured to receive encryptions keys transmitted from nodes in the network and to store the encryption keys in a database of the key archive.
