                Multipath Transmission for 6LoWPAN Networks
                  draft-pu-6lo-multipath-transmission-03

Abstract

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

1. Introduction

   6LoWPAN can deploy large-scale and high-density wireless personal
   area network devices with its high popularity, applicability, and
   more address space. However, due to the low processing power, the
   limited energy and the poor communication environment of the 6LoWPAN
   network, packets are easily lost during transmission, which causes
   transmission failure. The use of multipath packet transmission
   technology in 6LoWPAN is of great significance for improving
   communication reliability and transmission performance. 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
