Problems solved by technology

[0013] 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

Embodiment 2

[0082] This embodiment provides an address allocation method based on the fusion of heterogeneous mesh networks. The method uses the UE to directly obtain the address from the gateway through the cellular network, that is, the UE and the gateway support the D2D mode, and the UE saves the gateway address information. see Figure 4 with Figure 5 , which are the application scenario schematic diagram and signaling flow chart of the D2D mode network access and address allocation method, respectively, Figure 4 The application scenario shown includes server base station 1, base station server 2, mobile terminal 3, gateway / coordinator 4, routing node 5 and terminal newly added sensor node 6, where the small node represents the routing node 5, and the large node represents the newly added sensor node 6. Sensor node 6, as shown in the figure, the steps of implementing the address allocation method based on heterogeneous mesh network fusion include:

Abstract

The invention provides an address allocation method based on the fusion of heterogeneous mesh networks. According to the address allocation method based on the fusion of heterogeneous mesh networks, an optimal path is worked out according to relevant information of a newly-added sensing node and information of a routing node to provide access service for the newly-added sensing node, and a network allocation address and access-related information are acquired from a gateway as soon as possible through an address mapping table provided by a base station, wherein the address mapping table is used for describing the mapping relationship between a honeycomb network side communication address and a communication channel and between a sensor network side communication address and the communication channel after a mobile terminal becomes a mobile gateway under the architecture in which a honeycomb network and a sensor network are fused. With the address allocation method of the invention, energy consumption and signaling consumption between sensor networks can be reduced, the time delay of network accessing can be reduced, and a remote node is ensured to be accessed into a network quickly.

Description

technical field [0001] 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 [0002] 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. [0003] 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...
