• Loss rate asymmetry. is type of asymmetry takes place
when the backward path is considerably more lossy than
the forward path. In ad hoc networks, this can be a seri-
ous issue as all links involved are wireless, which is highly
error prone and dependent on local constraints that can
vary from place to place and also due to the mobile nature
of the network.
• Media access asymmetry. is can occur due to the characteris-
tics of the shared wireless medium used in ad hoc networks.
Specifically, in this kind of network, TCP ACKs have to
contend for the medium along with TCP data, and this may
cause excessive delay as well as discarding on TCP ACKs.
• Route asymmetry. Unlike the preceding three forms of asy
