Problems solved by technology

However, most existing methods are not suitable for the heterogeneous connection requirements of M2M networks, because they all assume that any pair of nodes has the same connection requirements, so it is necessary to design new topology control methods for M2M networks

Embodiment Construction

[0025] A distributed topology control method for heterogeneous connectivity services in an M2M network, the specific implementation is as follows:

[0026] The first step is initialization. The set of all common nodes in the entire M2M network is {v 1 ,v 2 ,...,v N}, the set of super nodes is {v N+1 , v N+2 ,...,v N+M}, all nodes are evenly distributed in a region in a two-dimensional Cartesian coordinate system whose length is lh and width is dh (dh<lh), and the converging node t is located at the coordinate position (0,dh / 2);

[0027] The second step is to establish the system model of M2M. An undirected graph G'=(V, E) is formed for all nodes of the entire M2M network and the connections between nodes, V represents the set of all nodes, and E represents the set of connections between any pair of neighboring nodes;

[0028] In the third step, the sink node t divides the entire target domain into k sub-domains, such as figure 1 , the entire target domain is equally di...

Abstract

The invention discloses a distributed topology control method for heterogeneous communication service in an M2M (Machine-to-Machine) network. Super nodes and common nodes exist in one M2M network; the distributed method is used for constructing k uncrossed paths between each super node and aggregation nodes, and constructing a path for the common nodes, so that heterogeneous connection requirements among different nodes and the aggregation nodes are satisfied. Meanwhile, the success rate of the whole network transmission is improved, and the power consumption of the whole network is reduced.

Description

technical field [0001] The invention relates to a topology control method for connectivity services in an M2M network, in particular to a distributed topology control method for heterogeneous connectivity services in an M2M network. Background technique [0002] In the past few years, the number of connected devices has grown rapidly. According to Cisco's forecast, the number of devices connected to the network will be no less than 1.5 billion, which will be three times the current number of mobile and Internet users. Therefore, the mainstream communication mode will inevitably change from human-to-human communication to machine-to-machine (M2M) communication. Different from traditional wireless self-organizing networks, M2M networks are composed of two types of nodes called super nodes and common nodes. For example, a home M2M network may consist of a sink node and a variety of daily household devices, such as some instrumentation , switches and biosensors, etc. The high...
