Abstract: Methods and system to determine the health of wireless mesh networks are provided. Each radio node of a wireless mesh network transmits Link Quantification Messages (LQMs) interPAN at maximum power to enable adjacent nodes to determine the Received Signal Strength Indication (RSSI) on the wireless link to that radio node. Each radio node also transmits LQMs at successively lower power levels. The adjacent nodes detect a power level at measurable packet error rate to determine a noise floor for the wireless link. An aggregator collects link quantification information from the radio nodes and forms an intercommunication matrix for the wireless network. The RSSI and power level at measurable packet error rate information is used to remove unreliable links from the intercommunication matrix. Nodes are ranked and the reliability and dependability of the nodes is calculated to show the network health.

Abstract: Identifying and protecting against malicious electronic messages that deceptively appear to originate from a trusted source. An authentic writing style contained within a legitimate electronic message that originates from a vender may be identified. The authentic writing style may be stored in a database. A new electronic message may be received that appears to originate from the vendor. The new electronic message may contain a new writing style. The new writing style may be compared with the authentic writing style stored in the database to identify any differences between the new writing style and the authentic writing style. A determination may be made that the new electronic message does not originate from the vender based, at least on part, on one or more differences identified between the writing styles. A security action may then be performed to protect against the new electronic message.
