                Multipath Transmission for 6LoWPAN Networks
                  draft-pu-6lo-multipath-transmission-00

Abstract

   This document provides a multipath transmission method for 6LoWPAN
   Networks, which can effectively offer the transmission redundancy of
   packets. It is applicable for high-reliability networks, especially
   for IPv6-based wireless industrial scenarios.

1. Introduction

   6LoWPAN has high popularity and applicability, and has more address
   space that can meet needs of the deployment of large-scale and high-
   density low-speed wireless personal area network devices. However,
   due to the low processing power, limited energy and poor
   communication environment in 6LoWPAN, packets are prone to be lost
   during transmission, resulting in transmission failure. In order to
   increase the communication reliability and improve the transmission
   performance of packets, it is very important to introduce multipath
   packet transmission technology in 6LoWPAN.
   RPL, as a routing protocol standardized by IETF, is an efficient
   distance vector protocol for wireless sensor networks, which has
   designed a series of new mechanisms [RFC6550], and is widely used in
   6LoWPAN. Aiming at the explicit demand of 6LoWPAN using multipath
   packet transmission, this document proposes a multipath transmission
   method based on RPL, which improves the success rate of packets
   transmission in uplink networks and further improves the network
   transmission reliability.
