Problems solved by technology

In this way, in the wireless sensor network using the existing network coding-aware routing, many sensor nodes do not need to monitor, but are set to promiscuous mode and are in the monitoring state, resulting in a large amount of unnecessary energy consumption, shortening the life of nodes and The network lifetime restricts the energy-saving performance of code-aware routing

Embodiment Construction

[0051] The flow chart of the network coding-aware cross-layer energy-saving routing method in the wireless sensor network is as follows: figure 1 As shown, the technical solution and method flow of the present invention will be further described in detail below.

[0052] (1) Forward routing request

[0053] The source node creates a route request message RREQ (Route REQuest) to the destination node. The RREQ message is forwarded by the relay node and sent to the destination node in a flooding manner.

[0054] The routing request message is forwarded by the relay node, and every time it reaches a relay node, it will collect the expected transmission times ETX (Expected Transmission Count) information of the link between the up-hop node and the current node, and the neighbor information of each relay node , and save the information in the routing request message RREQ.

[0055] (2) Backward routing return

[0056] After the route request message RREQ reaches the destination n...

Abstract

The invention discloses a method for network code sensing cross-layer energy-saving routing in a wireless sensor network. The method for network code sensing cross-layer energy-saving routing in the wireless sensor network mainly comprises the steps that (1) inter-flow network coding is used to reduce the frequency of data transmission and energy consumption, (2) a cross-layer mechanism among a network layer, a data link layer and a physical layer is used to determine monitoring nodes in a network, then a large amount of energy consumption, used for unnecessary monitoring, of nodes is reduced, the lifetime of the nodes is prolonged, and therefore the lifetime of the network is prolonged. According to the method for network code sensing cross-layer energy-saving routing in the wireless sensor network, the cross-layer mechanism is used for network code sensing routing, the number of the monitoring nodes is greatly reduced by means of the cross-layer mechanism on the premise that the inter-flow network coding is used to reduce the frequency of data transmission and the energy consumption, unnecessary energy consumption of a large number of nodes for monitoring in existing network code sensing routing is eliminated, therefore, energy consumption of sensing nodes in the wireless sensor network is reduced, and the network lifetime of the sensor network is prolonged.

Description

technical field [0001] The invention is specifically a network coding-aware cross-layer energy-saving routing method in a wireless sensor network, which is mainly suitable for routing discovery and data transmission path selection in a wireless sensor network, and introduces cross-layer thinking into code-aware routing. Only the monitoring of necessary nodes is turned on, and the monitoring of other nodes is turned off, so that on the basis of using network coding to reduce the number of data transmissions, the energy consumption of nodes is further reduced and the network survival time is prolonged. It belongs to the field of wireless network technology. Background technique [0002] The wireless sensor network is composed of a large number of sensor nodes deployed in the monitoring area. It is a wireless, multi-hop, self-organizing network formed by wireless communication. Its purpose is to send the information of the sensing objects in the network coverage area to the obs...
