Abstract

The concept of performability takes into accounts both availability and performance of a system. The issue of performability is very important for cellular networks due to its inherent characteristics like scarce of radio resources, high failure & outage rate and above all anytime, anywhere service expectation of the subscribers. In this work, first an algorithm is proposed for providing coverage to the users of failed cell/sector till it is repaired. The algorithm distributes the impact of a cell failure into whole network such that the fairness is maintained in the system despite the failure, thus it provides fault tolerance to the system. Then the performability of the cellular system is studied with the proposed algorithm
容错分段蜂窝网络的性能分析
可执行性的概念考虑了系统的可用性和性能。由于蜂窝网络固有的无线电资源稀缺、高故障率和高中断率以及用户对随时随地服务的期望等特点,蜂窝网络的性能问题非常重要。在这项工作中,首先提出了一种算法,用于为故障小区/扇区的用户提供覆盖,直到它被修复。该算法将单元故障的影响分散到整个网络中,使系统在发生故障时仍能保持系统的公平性,从而为系统提供容错能力。然后利用该算法对元胞系统的可执行性进行了研究
