Theoretical Analysis for Determining Geographical Route of Cable Network with Various Disaster-Endurance Levels (2105.00151v1)
Published 1 May 2021 in cs.NI
Abstract: This paper theoretically analyzes cable network disconnection due to randomly occurring natural disasters, where the disaster-endurance (DE) levels of the network are determined by a network entity such as the type of shielding method used for a duct containing cables. The network operator can determine which parts have a high DE level. When a part of a network can be protected, the placement of that part can be specified to decrease the probability of disconnecting two given nodes. The maximum lower bound of the probability of connecting two given nodes is explicitly derived. Conditions decreasing (not decreasing) the probability of connecting two given nodes with a partially protected network are provided.
