无线自组网资源分配机制的研究

Research of Resource Allocation Mechanism in Wireless Ad Hoc Networks

摘要: 无线自组网的应用邻域非常广泛，可以应用在军事通信、灾后紧急应用、个人通信、传感器邻域等，随着通信技术的发展人们对无线自组网络提出了越来越高的要求，保证高水平的网络性能成了研究关键。其性能受到诸多因素的影响，如组网规模、网络拓扑、节点分布、节点移动性等，所以如何合理地调度有限的网络资源，提高网络资源利用率成为研究中需要解决的问题。综上，如何在有限的信道资源约束下，合理地分配信道资源，解决多个节点共享无线信道的时候会造成信道资源分配不均的现象是一个迫切的任务。

Abstract: Wireless ad hoc networks are widely used in military communications, emergency applications after disasters, personal communications, sensor neighborhoods and so on. With the development of communication technology, people put forward higher and higher requirements for wireless ad hoc networks, and ensuring high-level network performance has become the key to research. Its performance is affected by many factors, such as network size, network topology, node distribution, node mobility and so on. Therefore, how to rationally schedule limited network resources and improve the utilization rate of network resources has become a problem to be solved in the research. In conclusion, it is an urgent task to allocate channel resources reasonably under the constraints of limited channel resources to solve the uneven distribution of channel resources when multiple nodes share wireless channels.
