Abstract

        Generally, planning and configuring cellular radio networks lead to multi-objective optimization problems with
conflicting objectives, e.g., coverage and cost. In this paper, we present an approach to combine those opponents in a closed-form objective for maximization of operator profit by means of joint base station and relay station placement in 4G multi-hop relay
networks. The corresponding optimization model is formulated
as mixed-integer linear program and particularly considers allocation of limited bandwidth for downlink data transmission in non-cooperative relaying mode. We suggest two economically motivated options how to choose appropriate weights for combin-
ing the conflicting objectives linearly. Furthermore, we apply the
proposed optimization model to an exemplary planning scenario to analyze sensitivity to weight modifications numerically.
Index Terms--Radio network planning, multi-hop relay net-works, multi-objective optimization, resource allocation.
