Method for implementing optimization unite connection allowance and route control of wireless mesh network

Abstract

The invention relates to a method for realizing optimization combined connection admission and routing control in a wireless mesh network, which comprises the steps of determining state space in the wireless mesh network and current state of a system, determining corresponding action space, determining and selecting corresponding action in the action space according to maximized network operating average reward criteria, executing the determined and selected action, updating the current state of the system, and returning and repeatedly executing the steps when a next event occurs in the wireless mesh network. The adoption of the method for realizing optimization combined connection admission and routing control in the wireless mesh network can optimally control admissible access or inadmissible access as well as admissible new connection or admissible switch connection access, ensures that the switch connection has highest priority in all connection requests of the same level, adapts to a plurality of service types and service conditions of the wireless mesh network, effectively improves the network service quality and the operating income, reduces the computational complexity, and has stable and reliable working performance, and wider application range.

Description

Technical field [0001] The present invention relates to the technical field of mobile communication, in particular to the technical field of control of service scheduling in a wireless mesh network, and specifically refers to a method for a wireless mesh network to achieve optimal joint connection permission and route control. Background technique [0002] The wireless mesh network is a multi-hop wireless network structure, which includes a mesh router and a mesh client. It is a new type of wireless network technology that is completely different from traditional wireless networks. The mesh router can form the backhaul link of the wireless mesh network. The biggest advantage of this structure is that if the nearest route is congested due to excessive traffic, the data can be automatically rerouted to a neighboring node with less traffic for transmission. By analogy, the data packet can also be routed to the next closest node for transmission according to the network situation unt...
