An optimization model for communication networks resilient to partial multiple link failures
(2014) 2014 INFORMS Telecommunications Conference- Abstract
- This submission is devoted to optimization of networks that permanently experience fluctuations
of the capacity available on their links. This is an important and novel topic since limited link availability is a fundamental feature in wireless networks and yet majority of
work in survivable network design is restricted to the total single link failures. We assume
a given finite set of network states. Each state is characterized by availability coefficients
specifying, for each link, the fraction of its reference capacity available in this state, and
by traffic coefficients specifying, for each demand, the proportion of its reference traffic to
be realized in the considered state. Our... (More) - This submission is devoted to optimization of networks that permanently experience fluctuations

work in survivable network design is restricted to the total single link failures. We assume
a given finite set of network states. Each state is characterized by availability coefficients
specifying, for each link, the fraction of its reference capacity available in this state, and
by traffic coefficients specifying, for each demand, the proportion of its reference traffic to
be realized in the considered state. Our routing strategy allows for thinning/thickening the
reference path-flows, with the thickening limited by a given upper bound U of the reference
value. Thus, in each state, the value of every path-flow can range from 0 to U times its
reference value. For the corresponding link cost minimization problem (where link capacities
and state-dependent path-flows are decision variables) we present a non-compact linear programming
model together with a solution algorithm based on path generation. We illustrate
the effectiveness of the introduced routing strategy by presenting numerical results for a set
of representative network examples. (Less)
