Embodiment Construction

[0044] In order to describe in more detail a HWMP-based network coding-aware wireless Mesh routing protocol CAHWMP proposed by the present invention, with reference to the accompanying drawings, an example is illustrated as follows:

[0045] CAHWMP, a network coding-aware wireless mesh routing protocol based on HWMP, uses the network coding-aware routing criterion NCCa, comprehensively considers the link channel resource consumption and the resource sharing gain brought by network coding, and can reflect the impact of network coding on the link. The impact of resource consumption; during the path discovery process, the CAHWMP protocol will start the coding opportunity detection algorithm, actively detect the coding opportunities of the nodes, and establish a path with more coding opportunities according to the NCCa criterion; the specific method is as follows:

[0046] Step A, based on the encoding judgment of the data flow path;

[0047] Define the network coding set: set at ...

Abstract

The invention provides a network coding perception wireless mesh routing protocol CAHWMP based on a hybrid wireless mesh protocol (HWMP). The CAHWMP protocol comprises a route criterion NCCa which has a network coding consciousness. The route criterion takes overall consideration of link channel resource consumption and resource sharing gains brought by network coding, and provides a coding criterion standard based on a data flow path, and a coding opportunity detection algorithm using the coding criterion standard. A path discovery process, a path reply process and a path maintenance process of the CAHWMP protocol are designed, the coding opportunity detection algorithm is utilized in the designing process, node coding opportunities are detected actively, and the NCCa criterion is used for building the paths with multiple coding opportunities. The CAHWMP protocol can find out more coding opportunities, further improve network throughput, lower average end-to-end delay and improve the delivery rate of a data packet.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and specifically refers to a network coding-aware wireless Mesh routing protocol based on HWMP. Background technique [0002] Wireless Mesh network is a new type of multi-hop network with wide coverage, large network capacity, fast access speed, and low deployment cost. It is a new solution to the "last mile" bottleneck problem. The design of routing protocols is one of the key issues in the research of wireless mesh networks. The design of routing protocols is directly related to whether the advantages of wireless mesh networks can be fully utilized. In 2000, R. Ahlswede and others proposed the idea of ​​network coding, which became a research hotspot in the field of communication and was widely studied. The idea of ​​network coding breaks through the traditional transmission mode in which network nodes can only store and forward, and allows network nodes to encode data packets bef...
