Embodiment Construction

[0036] In the article "Analysis and Research of AODV Routing Protocol in Ad Hoc Network" (Author: Jing Wenli, Le Hongbing. "Computer System Application", Volume 19, Issue 10, 2010), the method of establishing the AODV routing table is introduced:

[0037] Step 1, the node initiates the route discovery process, and broadcasts RREQ control information to its neighbor nodes.

[0038] Step 2, after the node receives the RREQ control information, it performs the following operations in sequence: a.) checks whether the routing table has routing information to the source node, and if not, establishes a reverse routing table; b.) judges whether the node is a destination node Or there is enough new routing information to reach the destination node, if yes, return RREP message, if not, continue to forward RREQ.

[0039] Step 3, during the RREP return process, the node receives the RREP message and operates sequentially: a.) Check whether there is routing information to the destination n...

Abstract

The invention provides an energy efficiency AODV routing protocol implementation method applicable to a wireless sensor network. The method comprises the following steps that 1, the network is initialized and set; 2, a source node initiates a route finding process; 3, the source node selects an optimal route; 4, after route finding is finished, in the route working process, a route error and route maintenance mechanism based on energy is increased. The energy efficiency AODV routing protocol implementation method applicable to the wireless sensor network not only can reduce energy consumption of the whole wireless sensor network, but also can delay the splitting time of the network, thereby prolonging the service life of the network and reducing resource waste caused by repeated network deployment.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for establishing a routing table based on an energy efficient AODV routing protocol of a wireless sensor network. Background technique [0002] With the development of wireless sensor network technology and its wide application in various fields, all walks of life are full of expectations for the development of wireless sensor network, and related research in the field of wireless sensor network has become a current research hotspot. However, due to the limitations of the wireless sensor network itself and the particularity of its application, its various technical performances cannot fully meet people's requirements for the time being. The effective use of the limited energy of each node in the network is a very important research aspect. [0003] Most of the wireless sensor network nodes are powered by batteries, and energy supply is difficult. In some cases, the ...
