Method for network code sensing cross-layer energy-saving routing in wireless sensor network

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.

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
