Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] In order to ensure the correct and reliable transmission of monitoring data in the tunnel, this paper performs redundant processing on the layout of network routing nodes in the tunnel, that is, routing nodes can skip transmission to avoid the physical death of a node and cause the paralysis of the wireless monitoring network. The schematic diagram of tunnel wireless monitoring network transmission is as follows figure 1 shown.

[0041] The routing decision strategy proposed in this solution is consistent with the AODV (Adhoc On-Demand Distance VectorRouting) routing protocol packet type, including routing request (RREQ: Routing REQuest), routing response (RREP: Routing REPly), and routing error (RERR: Routing ERRor). ), HELLO package and user data package. The routing error and the data structure of the heartbeat ...

Abstract

The invention discloses an energy-efficient routing decision-making method for a wireless sensor network in a tunnel environment, comprising the following steps: a tunnel node initiates a routing request as a source node, and at the same time initializes a routing request frame; after the routing node receives the routing request, it calculates a decision Factor ETX,E i And E3TX and update the routing table, check whether there is an entry to the destination node in the routing table, if there is a routing response; when the routing node receives the routing response, the node compares the locally calculated information with the data in the routing response frame, and satisfies Conditions are then forwarded to the source node to stop and generate a reverse route; the present invention uses routing decision algorithms to combine energy efficiency, hop count, ETX and reliability to obtain the optimal path from the source node to the destination node, and solves the time delay and Reliability issues.

Description

technical field [0001] The invention relates to an optimal wireless transmission path decision for a wireless sensor network, in particular to an energy-efficient routing decision method for a wireless sensor network in a tunnel environment. Background technique [0002] In actual wireless transmission network applications such as construction and operation tunnel health monitoring, due to the complex environment and special distribution of network nodes, traditional routing protocols cannot guarantee energy consumption and network reliability in complex tunnel environments. In the tunnel environment, it is difficult for the routing to exist in the multi-path routing of the conventional network, but it is usually a straight single-path routing, but it has a more significant multi-path effect than the conventional environment. In order to solve the energy efficiency and network reliability of the wireless transmission network in the tunnel environment, it is necessary to cons...
