Abstract 6LoWPAN protocol supports IPv6 datagram delivering over IEEE 802.15.4-based low-power wireless personal area network, and its main functions include fragmenting and reassembling IPv6 datagrams, header compression, and routing. In this paper, the number of transmissions, the delay and the throughput of multi-path routing for delivering an IPv6 datagram to the destination from the source are derived based on probability theory. Moreover, the model that optimizes the throughput of multi-path routing is developed, and based on this model the optimal fragmentation scheme is proposed. The proposed scheme is able to improve the throughput of IPv6 datagrams in 6LoWPAN.
