[0098] Design and Implementation of Adaptation Layer

[0099] After modification, the header format of the non-fragmented adaptation layer encapsulation is shown in Table 8:

[0100] LF(2)

data type(5)

M(1)

RID(8)

IPv6 data packet (or final destination address header)

[0101] The definition of the format field of the non-fragmented adaptation layer encapsulation header in Table 8 is as follows:

[0102] RID: router identifier, routing identifier. This is an independent creation of the present invention. An 8-bit sequence number used to distinguish multiple data streams from the same intermediate node. Each RID corresponds to a piece of routing information. Entries with different destination addresses in the routing table may have the same RID.

[0103] After modification, the encapsulation format of the first fragment is shown in Table 9.

[0104] LF(2)

Abstract

This invention relates to a method for realizing the support of compression packets parallel transmission on IPV 6 sensor network, which solves the problem of prallel transmission of multiple data streams between any two sensor network nodes under the mode of transmitting IPV 6 data packet compressed by the packet head via net-link routes using wireless sensor network. This invention introduces a route ID symbol domain to the frame form of an applied layer, an eight bit sequence number, one is suitable for multi-hop compression transmission route algorithm based on the network topology.

Description

Technical field [0001] The invention relates to a method for realizing parallel transmission of compressed packets in an IPv6 sensor network, and belongs to the technical field of computer networks. Background technique [0002] The wireless sensor network is composed of a large number of low-power, low-speed, low-cost, high-density micro-nodes, and the nodes form a network through self-organization and self-healing. The use of wireless sensor networks can realize data collection and quantification, processing fusion and transmission applications. Wireless sensor networks can be deployed in the fields of home, hospital, military, environmental monitoring and industrial control, using various sensors to measure temperature, humidity, noise, pressure And other signals, thereby improving people's existing quality of life and production efficiency. [0003] In November 2004, the IETF formally established the 6LOWPAN working group, which started to formulate the IPv6-based wirel...
