Description

An Address Assignment Method Based on Heterogeneous Mesh Network Convergence

technical field

The invention belongs to the technical field of mobile wireless communication, and relates to an address allocation method, in particular to an address allocation method based on fusion of heterogeneous mesh networks.

Background technique

Wireless sensor network is an emerging network technology with great development potential. This network can randomly deploy a large number of simple nodes in a certain area with large redundancy. Real-time monitoring, sensing and collecting information of various complex environments or monitoring objects in the network distribution area, and processing these information in the network, so as to obtain detailed and accurate information and transmit it to the background backbone network server or related observers.

In wireless sensor network applications, sensor nodes need to obtain permission from the gateway or coordinator and assign network addresses to access the network. Generally speaking, the coverage of a mesh network is much larger than that of other topological networks. Therefore, as the network scale expands, when a node at the edge of the network needs to join, the access request message needs to go through multiple hops to reach the gateway or coordinator. , which will consume a large amount of energy and channel resources, increase the probability of network conflicts, and increase the end-to-end access delay accordingly, resulting in excessive energy consumption of intermediate routing nodes, affecting the network life cycle and degrading network performance.

Usually, the coverage area of the wireless sensor network with the mesh structure is relatively large, and the gateway/coordinator centrally assigns 16-bit network addresses to the sensor nodes. When a node relatively far from the gateway enters the network, it needs to send an access request to the gateway, and the gateway decides whether to accept the addition of the new node and assigns a network address. The access request signaling reaches the gateway through a multi-hop route, which increases the delay of the access process and consumes more signaling transmission energy, which accelerates the energy consumption of intermediate routing nodes and affects the life cycle of the network .

The general steps of the traditional algorithm include:

1. When a new sensor node joins the network, broadcast an access request.

2. All routing nodes or gateways that receive the access request will reply with a personal area network (PAN, Personal Area Network) address and LQI value.

3. The relay routing node selects the optimal next-hop node according to the LQI value and sends an access request.

4. The next hop node sends the access request to the gateway according to the routing table.

5. If the number of nodes in the network exceeds the threshold, the gateway will send a rejection reply, otherwise, the gateway will send a reception reply and assign a 16-bit network address.

Among them, the wireless mesh sensor network is composed of a large number of static nodes scattered in a certain geographical area. The gateway initiates the initial networking. The routing path, through multi-hop transmission network request to the remote gateway node. Usually, these nodes have similar energy, storage, computing, and transmission capabilities, that is, the nodes are isomorphic, and their data flows mostly show the characteristics of "many-to-one".

With the expansion of the network scale and the increase in the number of hops for incoming and outgoing network requests, the traditional algorithm will inevitably form a bottleneck node at the gateway, increasing the access delay and degrading network performance.

Contents of the invention

In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an address allocation method based on the integration of heterogeneous mesh networks, which is used to solve the problem of consuming a large amount of energy and channel resources when the number of network access requests increases in the prior art. The problem of increasing the probability of network conflict and increasing the end-to-end access delay leads to the excessive consumption of energy of intermediate routing nodes.

In order to achieve the above purpose and other related purposes, the present invention provides an address allocation method based on heterogeneous mesh network fusion, including:

If routing node i is a gateway, then H _W (i) = 0; H _G (i) is the current reachability of routing node i The minimum hop count of the gateway, if H _W (i) = H _C (i), then the path with UE involved in the transmission will be selected as the address allocation path of routing node i;
