Problems solved by technology

In the hybrid network formed by the fusion of the cellular network and the self-organizing network, the centralized static allocation of resources reduces the resource negotiation steps, but this method has serious resource waste problems. When a node does not need to transmit data, The resources it occupies cannot be used by other nodes
The centralized and dynamic allocation of channel resources can dynamically apply for network resources according to the needs of business transmission, which can avoid system resource conflicts, but there is a problem of system delay in the dynamic application of centralized allocation of resources

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] Such as figure 1 As shown, the hybrid network dynamic channel resource allocation method includes the following steps:

[0019] Step 1. Centrally and statically allocate a small amount of resources according to the network topology;

[0020] Step 2. When the node as the requester has a service request and the trigger condition is satisfied, the requester node sends a negotiation message frame to the receiver nod...

Abstract

The invention relates to the technical field of the communication, and specifically discloses a hybrid network dynamic channel resource allocation method. The method comprises the following steps: statically allocating a small amount of resources in a centralized according to a network topology structure, and dynamically allocating residual network resources in a distributed way between the nodesaccording to service transmission demand; the wireless network resource interference is reduced, and the wireless network resource is sufficiently utilized; the defect that the less network node amount under the star configuration cannot satisfy the actual application demand since the resource is wasted and the neighbor amount allowed to possess by the node is limited under the condition that theexisting centralized static resource allocation way cannot dynamically apply the resource according to the node service transmission node is solved, and the defect that the delay is caused since the use of any resource needs to apply at first in the centralized dynamic distributing way is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dynamic channel resource allocation method of a hybrid network. Background technique [0002] Cellular networks and ad hoc networks are important components of mobile communication systems, and the hybrid network that combines them has become one of the research hotspots in current mobile communication systems. The hybrid network has the characteristics of both cellular network and ad hoc network. Its network users can use a single terminal to dynamically form a local area subnet within a certain range, enjoy surrounding service resources, and access the base station through multi-hop forwarding to obtain wide area network services. Good flexibility and expansibility make the hybrid network an important form of the existing mobile communication network. [0003] Channel resource allocation mechanism is one of the main technical issues of hybrid network. In the case of ...
