A survivability strategy in mobile networks

초록

The capability to provide network service must survive even if a significant network system element is disrupted. To sustain network service under a system failure, network survivability mechanisms minimizing the impact of failures are needed. Also, since the mobile network has its own unique characteristics, a survivability scheme for the vulnerability of the mobile network is required. This paper proposes a survivability scheme to support reliable service of the wireless access point level (BS-base station system). With the survivability scheme, the mobile network can use an overlap BS of the cellular network architecture after a BS system failure. We analyze the performance of the proposed scheme using the Markov model. Also, a computer simulation is used for the scheme analysis. The proposed scheme shows that service of the mobile network can be provided under the BS system failure.
