Problems solved by technology

However, if the network environment is complex and the number of nodes is large, it is easy to cause conflicts in control information. If the control channel is interfered, it will affect the performance of the entire network.

Embodiment Construction

[0044] The technical solution of the present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation methods.

[0045] This specific implementation mode discloses a method for allocating air interface resources for single transmission and multiple reception, including a control channel allocation process and a data channel allocation process, wherein:

[0046] Control channel allocation process: divide the control channel into reserved time slots and contention time slots in the time domain. At any time, if the node needs to use the control channel, if it finds that there is a reserved time slot available to the node, it will directly use the reserved time slot; if it finds that there is no reserved time slot available to the node, it will compete with other nodes to use the contention time slot gap;

[0047] Data channel allocation process: Use the control channel to negotiate an available data channel.

Abstract

The invention provides a single transmitter to double receiver vacant resource allocation method which comprises a control channel allocation process and a data channel allocation process. The control channel allocation process comprises the steps that a control channel is divided into a reserved time slot and a competition time slot in time domain; at some point, if a node needs to use a control channel and if the reserved time slot available for the node is found, the reserved time slot is directly used; and if the reserved time slot available for the node is not found, the node competes for the competition time slot with other nodes. According to the data channel allocation process, the control channel is used to negotiate a data channel which can be used. According to the invention, the multi-channel way is used to realize parallel transmission of node data, which effectively improves the network capacity; a multi-channel frequency division multiplexing technology is used, which effectively reduces mutual interference of neighbor nodes and improves the wireless transmission efficiency; and a TDMA hybrid channel access method is used, which effectively reduces the collision probability of data packets and realizes efficient packet transmission.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for allocating single-send-multiple-receive air interface resources. Background technique [0002] Compared with traditional wireless communication networks, wireless ad hoc networks have the characteristics of fast networking, low requirements for infrastructure, and strong resistance to destruction. They are widely used in military communications, rescue and disaster relief, and intelligent transportation. [0003] Similar to the OSI model of the TCP / IP protocol stack, the underlying protocol stack of the wireless ad hoc network can also be divided into a physical layer (PHY), a medium access control layer (MAC) and a network layer (NET), where the network layer is responsible for the routing of nodes Maintenance and message forwarding, the physical layer realizes the sending and receiving of air interface data. The MAC layer is responsible for the allocation of ...
