Using network coding in 6LoWPAN WSNs

The low power wireless sensor devices which usually uses the low power wireless private area network (IEEE 802.15.4) standard are being widely deployed for various purposes and in different scenarios both in civil and military world. IPv6 low power wireless private area network (6LoWPAN) was adopted as part of the IETF standard for the wireless sensor devices in order to decrease the IP overhead and to adapt big IPv6 packets to small maximum transmission unit (MTU) offered by the IEEE 802.15.4 standard. This paper is focused on the adoption of the network coding to 6LoWPAN/IEEE 802.15.4 network. The solution based on COPE mechanism is proposed and described here. Also the implementation problems are discussed.
