Mesh Link Establishment (MLE) is a protocol
that provides radio links in changing network topologies. Mesh Link Establishment (MLE) is used in radio protocols based on 6LoWPAN
, among others.In such networks based on 802.15.4, the radio parameters such as the received field strength or the channel characteristics are transmitted separately as a TLV data set
(Type, Length, Value). If theconnection parameters change, the MLE protocol dynamically adapts the network
to thenew conditions.
Each individual network node stores the connection parameters to its neighboring nodes and updates the tables as soon as the connection quality changes.
