Link/medium access control layer: This layer suffers
mainly from collision, exhaustion, and unfairness attacks.
In collision attacks, an adversary simultaneously transmits
the packets at same frequency, resulting in packet collision
and degradation of the network performance. In exhaustion
attacks the battery source is self-sacrificing, since wireless
nodes most of the time maintains the channel active. In
unfairness attacks, network performance degrades because
this layer priority is generally disrupted according to the
application requirements.
