IPv6-based wireless sensor network and Internet multi-gateway interconnection scheme

Abstract

The invention provides an IPv6-based wireless sensor network and Internet multi-gateway interconnection scheme. An IPv6 wireless sensor network complies with a 6LoWPAN (IPv6 over Low power Wireless Personal Area Networks) standard. The IPv6-based wireless sensor network and Internet multi-gateway interconnection scheme comprises the steps that a root-LBR serving as a root gateway and a plurality of LBRs serving as ordinary gateways are introduced in existing 6LoWPAN, and an IP internetwork route with an extended RPL routing algorithm is adopted in the 6LoWPAN, an IP tunnel scheme is adopted between the root-LBR and the LBRs to achieve IP wired high-speed communication between the root-LBR and the LBRs, and then network interconnection and routing between the IPv6 wireless sensor network and the Internet of the former level are conducted through the root-LBR in a unified mode. According to the IPv6-based wireless sensor network and Internet multi-gateway interconnection scheme, the power consumption of a wireless IP gateway is reduced, nodes of the wireless gateway achieve load sharing, the network lifetime is prolonged, the capacity of internetwork connection is improved, and interconnection delay is reduced.

Description

technical field [0001] The invention relates to a connection method in realizing interconnection between an IPv6-based wireless sensor network (WSN) and the Internet, and an interconnection scheme between an IP-based wireless sensor network and the Internet. Background technique [0002] Wireless sensor network is a wireless personal area network that requires low power consumption. It connects a large number of sensor nodes or intelligent application nodes, and is the core technology of the Internet of Things. Applying IP technology to wireless sensor networks to realize the seamless connection of wireless and wired IP networks is the basic requirement of the IoT network. [0003] The next-generation Internet IPv6 provides a wealth of network node addresses. After tailoring the IP protocol stack and applying it to the wireless sensor network, each node is assigned an IP address, which can realize the seamless connection between the wireless sensor network and the traditiona...

Problems solved by technology

The method of a single Internet gateway will cause the WSN Internet traffic to converge to the gateway node, which will not only increase the power consumption of the gateway and WSN nodes whose topology is close to the gateway, but also cause channel congestion, resulting in unbalanced power consumption and load; the multi-cluster connection method can reduce The power consumption and load pressure of the gateway, but reasonable cluster management is required. Once clustered, it is diff
