6LoWPAN defines how to carry IPv6 packets over IEEE 802.15.4
low power wireless or sensor networks. Limited bandwidth, memory and energy
resources require a careful application of IPv6 in a LoWPAN. The
IEEE 802.15.4 standard defines a maximum frame size of 127 bytes that decreases
to 102 bytes considering the header overhead. A further reduction is due
to the security, network and transport protocols header overhead that, in case of
IPv6 and UDP, leave only 33 bytes for application data. A compression algorithm
is necessary in order to reduce the overhead and save space in data payload.
This paper describes and compares the proposed IPv6 header compression
mechanisms for 6LoWPAN environments.
