Example Embodiment

[0030] In order to realize high-performance wireless Ad Hoc network resource planning, the present invention provides a technical solution for different types of wireless multicast service requirements, so that the bandwidth resource allocation result can simultaneously satisfy the multicast service quality and the optimal network utilization rate.

[0031] System structure as attached figure 2 As shown, the multicast service source node adjustment unit is set at the multicast service source node as the sender of the multicast service, an interference area resource allocation unit is set in each interference area, and the multicast service destination node as the receiver of the multicast service is set Multicast service destination node feedback unit. When the specific implementation is applied to a wireless Ad Hoc network, it is recommended that the routing is implemented using the AODV protocol, the MAC layer is implemented using standard 802.11, and the transmission protocol ...

Abstract

The invention relates to an AdHoc network heterogeneous multicast service flow optimal resource control method. The method comprises the following steps: setting a multicast service source node adjusting unit on a multicast service source node serving as a transmission end of multicast service; setting an interference region resource distribution unit in each interference region; setting a multicast service targeting node feedback unit on a multicast service targeting node serving as a multicast service receiving end; executing the number of sub-flows to be distributed; recording the number of classifying bandwidth of the multicast service; calculating the total price generated by each layer of the multicast sub-flow; calculating the total length of sub-flow links of all multicast service; updating the bidding information of each multicast service stratified sub-flow; and updating the resource price of the interference region. By the method, optimal resource distribution of a wireless AdHoc network heterogeneous multicast service flow under dynamic environment can be obtained. The method improves the network service quality of the heterogeneous multicast service flow with different bandwidth expectation, and has the advantages of elastically adapting to various network scales.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for optimal resource control of heterogeneous multicast service flow in a wireless Ad Hoc network. Background technique [0002] In the 1990s, the network business showed the characteristics of diversified business types, and various applications have penetrated into all aspects of people's daily life, and are playing an increasingly important role in the current social and economic life. The development of wireless multimedia is particularly rapid, and an important network support for wireless multimedia transmission is wireless multicast. Under such application background, wireless multicast has been paid more and more attention by people. While network device performance and network transmission speeds continue to improve, bandwidth cost and availability remain major barriers to control implementation. Therefore, it is necessary to design reasonable wireless network contro...
