Embodiment 1

[0061] In the first embodiment, the access gateway stores the virtual IPV6 address in advance, and resolves the IPV6 address after receiving the access request sent by the user, so that the user can access the target node.

[0062] see figure 2 As shown, the flow of the power wireless sensor network communication method in Embodiment 1 is as follows:

[0063] Step 201: The access gateway extracts the address information of the sink node, the address information of the target node and the protocol type of the target node according to the unique data packet of the sensor network.

[0064] Step 202: generate a virtual IPV6 address according to the hash algorithm based on the address information of the aggregation node, the address information of the target node, the protocol type of the target node, and the IP address of the access gateway, and store the virtual IPV6 address.

[0065] Wherein, a target node corresponds to a unique virtual IPv6 address. In Embodiment 1, the vir...

Abstract

The present invention discloses a communication method of a power wireless sensing network, an access gateway and a system. The method comprises a step of receiving the visit target node request which comprises a virtual IPV6 address sent by an external user, a step of parsing the virtual IPV6 address and determining sink node address information, target node address information and a target node protocol type, and a step of packaging a sensing network protocol packet according to the sink node address information, the target node address information and the target node protocol type and visiting a target node. The rapid mapping between the external user and the target node can be realized, thus the real-time addressing is realized, the characteristics of the sensor network are not affected, and the transparency of network access is improved. The mapping between a virtual IP and the target node is realized by a hashing algorithm, the query latency is effectively reduced, and the mapping efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of electric power wireless sensor network in the field of sensors, in particular to a communication method, access gateway and system of electric power wireless sensor network. Background technique [0002] In the power wireless sensor network system architecture, the wireless sensor network access gateway undertakes functions such as heterogeneous sensor network information aggregation, external network TCP / IP connection, and communication protocol conversion. Huge number, frequent updates and so on. With the evolution of IPv6, business systems or users generally hope that each sensor node has a unique IP address and supports direct access through IP, thus deriving some tailored versions of TCP / IP communication protocols suitable for wireless sensor networks , such as 6LowPan, etc., but the power wireless sensor network is limited by factors such as node energy consumption and channel bandwidth, an...
