                Multipath Transmission for 6LoWPAN Networks
                  draft-pu-6lo-multipath-transmission-02

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 realize the deployment of large-scale and high-
   density wireless personal area network devices. However, packets are
   prone to be lost during transmission due to the low processing power,
   limited energy and poor communication environment in 6LoWPAN, which
   results in transmission failure. In order to increase the
   communication reliability and improve the transmission performance,
   it is of great significance to introduce multipath packet
   transmission technology in 6LoWPAN. It is well known that 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 requirement of multi-path packet transmission
   for 6LoWPAN, this document proposes an RPL-based multipath

   transmission method, which improves the success rate of packets
   transmission in uplink networks and further enhances the
   transmission reliability.
