Evaluating Reliability/Survivability of Capacitated Wireless Networks
(Institute of Electrical and Electronics Engineers Inc., 2018) Ozgur Kabadurmus; Alice E. Smith; Kabadurmus, Ozgur; Smith, Alice E.
In telecommunication network design problems survivability and reliability are often used to evaluate quality of service while usually ignoring link capacity. In this paper a new metric that combines network reliability with network resilience is presented to measure reliability/survivability effectively for capacitated networks. Capacitated resilience is compared with well-known network reliability/survivability metrics ( K-terminal reliability all-terminal reliability traffic efficiency and K-connectivity) and its benefits and computational efficiency are discussed. An application is shown using heterogeneous wireless networks (HetNets). With the growing use of new telecommunication technologies such as 4G and wireless hotspots HetNets are gaining more attention. The source of heterogeneity of a HetNet can either be the differences in nodes (such as transmission ranges failure rates and energy levels) or the differences in services offered in the network (such as GSM and WiFi). © 2018 Elsevier B.V.

Multi-commodity k-splittable survivable network design problems with relays
(SPRINGER, 2016) Ozgur Kabadurmus; Alice E. Smith; Kabadurmus, Ozgur; Smith, Alice E.
The network design problem is a well known optimization problem with applications in telecommunication infrastructure designs and military operations. This paper devises the first formulation and solution methodology for the multi-commodity k-splittable two-edge disjoint survivable network design problem with capacitated edges and relays. This problem realistically portrays telecommunications network design but has not been solved previously due to its computational difficulty. Edge capacity is considered as either a discrete or a continuous variable. An exact method and a practical heuristic method are presented and computational results are discussed.
