Wireless sensor network AODV routing protocol implementation system and method

Abstract

The invention relates to a wireless sensor network AODV routing protocol implementation system and method. When a sending source node does not detect the routing information of a node which reaches a destination, a routing request carrying the routing forwarding cost factor weight is broadcasted to surrounding nodes. An intermediate node receives the routing request, calculates the power level factor and the load state factor of the node, and determines whether the node is suitable for the transmission of the routing request. If the node is suitable for the transmission of the routing request, the intermediate node updates the routing forwarding cost factor weight carried by the routing request according to the power level factor, the load state factor and the hop weight of the node, and forwards the updated routing request. Based on the power level factor of the node, the load state factor of the node and the hop weight, the node energy and the load condition are taken into account in the process of routing selection to avoid routing in the node with congestion and insufficient residual energy. The system and method meet the application requirements of a wireless sensor network. The data transmission performance of the wireless sensor network is improved.

Description

Technical field [0001] The invention relates to the technical field of power grid communication, in particular to a system and method for implementing an AODV routing protocol in a wireless sensor network. Background technique [0002] Energy storage hydropower stations are important infrastructures in smart grids, which can realize the efficient utilization and income of electric energy through the conversion of hydroelectric energy during the peak and valley periods of grid load. Due to the special requirements for the site selection and construction of energy storage hydropower stations, most of the energy storage hydropower stations in the power grid cover a large area and are located in deep mountains and valleys with inconvenient communications. The powerhouse of the hydropower station is an underground cave-like powerhouse with few people on duty. It mainly realizes the collection and monitoring of the environmental parameters of the entire power storage plant by wireless ...

Problems solved by technology

Since only the number of node hops is considered, and the actual situation of the nodes is not considered, the data transmission delay will increase, the packet loss rate will increase, and the data transmission performance of the wireless sensor network will decrease.
