Embodiment Construction

[0021] The implementation process of the mobile ad hoc network admission control method based on game theory can be seen in figure 1 Shown: It mainly includes control functional entity (CFE) and decision-making functional entity (DFE). CFE is responsible for collecting and maintaining network resource status information, user requirements and DFE decisions, etc., and implements admission control on the transport network according to DFE decisions. DFE makes the final decision on network resource admission control according to the status of available network resources, service priority, service QoS requirements, and user QoS satisfaction. CFE is responsible for the implementation of admission control decision results. The process of admission control mainly includes obtaining the status of network resources, calculating user satisfaction, playing admission control game, determining the game result and executing the decision result.

[0022] The network resource status acquisi...

Abstract

The invention relates to a Mobile Ad-hoc NETwork (MANET) resource admission control method based on a game theory. A network user satisfaction index and a business loss rate are defined by the method, and a Mobile Ad-hoc NETwork resource admission control problem is subjected to modeling based on the game theory. A system of the method comprises a control function entity (CFE) and a decision function entity (DFE). The method comprises the following steps: the CFE acquires present network resource state information and user demand information, and sends the information to the DFE; based on calculation of a user satisfaction index, the DFE completes a game process according to a pay off matrix between service and network access control points, obtains an admission control decision result ofadmitting, rejecting, or blocking, and deliveries the result to the CFE; the CFE executes the admission control decision result. According to the invention, adaptability of an admission control mechanism to real-time services with different service quality sensitivities is enhanced, and service qualities of the services are ensured.

Description

technical field [0001] The invention belongs to a service quality assurance method in a mobile self-organizing network, in particular a resource admission control method based on game theory to distinguish service QoS sensitivity. Background technique [0002] With the development of mobile ad hoc network (MANET) technology, it becomes possible to run real-time applications on the network. Real-time applications have relatively strict quality of service (QoS) requirements, and the network needs to guarantee its QoS. These requirements include end-to-end delay, bandwidth, throughput, etc. Whether the network resources can meet the application requirements is very important, otherwise the application availability will be deteriorated, and users will also get unsatisfactory experience. [0003] Because the MANET network lacks centralized control, the nodes have mobility, and the wireless network channel is unreliable and prone to congestion, it is difficult to provide strictl...
