Embodiment 1

[0030] This embodiment provides an address allocation method in a sensor network, such as figure 1 As shown, the method includes:

[0031] 101. Segment the total address space in units of address spaces that can be allocated in the sensor network to obtain multiple address spaces including a first segment address space and a second segment address space.

[0032] In an example, the address space size S that can be allocated in the sensor network skip for:

[0033] S skip = R m × ( 1 + C m - R m - C m × R m ...

Embodiment 2

[0042] This embodiment provides an address allocation method in a sensor network. Among the divided multi-segment address spaces, the first segment address space is used first. Segment address space, using the extended address space to allocate addresses for nodes, the specific allocation process can be as follows figure 2 As shown, the method includes:

[0043] 201. The parent node segments the total address space in units of address spaces that can be allocated in the sensor network to obtain multiple address spaces including the first segment address space and the second segment address space, wherein the sensor The address space size S that can be allocated in the network skip for:

[0044] S skip = R m × ( 1 + C m - ...

Embodiment 3

[0073] This embodiment provides a sensor network node, such as image 3 As shown, the sensor network nodes include:

[0074]A segmentation module 301, configured to segment the total address space in units of address spaces that can be allocated in the sensor network, to obtain multiple address spaces including the first segment address space and the second segment address space;

[0075] The allocating module 302 is configured to allocate addresses in the second address space for child nodes when the first address space is exhausted.

[0076] Wherein, the first segment address space is the first segment address space in the multi-segment address space, and the second segment address space is an extended address space in the multi-segment address space; or

[0077] The first segment address space and the second segment address space are respectively two extended address spaces in the multi-segment address space.

[0078] The address space of the second segment is adjacent or...

Abstract

The embodiment of the invention discloses an address distribution method in a sensor network and a sensor network node. The method comprises the following steps of segmenting a total address space by taking address spaces, which can be distributed in the sensor network, as a unit to obtain a multi-segment address space containing a first section address space and a second section address space; and when running out of the first-section address space, distributing an address in the second section address space to a child node. The invention is suitable for address distribution in the sensor network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an address allocation method in a sensor network and a node of the sensor network. Background technique [0002] Wireless sensor network is a self-organized, task-oriented, data-centric wireless communication network composed of a large number of sensor nodes distributed in a wide area. At present, the commonly used address allocation method provided by the wireless sensor network protocol is a distributed address allocation method. In a distributed address allocation method, the network coordinator first sets some network parameters, such as: the maximum number of child nodes that a parent node can have C m , the maximum number R of child nodes with routing functions that a parent node can have m , the maximum depth L of the network m . Then, for a parent node with a depth of d, the size of the address space allocated to its child nodes is C skip (d) is given...
