A new technique for combinational logic optimization is described. The technique is a two-
step process. In the first step, the non-linearity of a circuit–as measured by the number of …

We propose a new solution to the problem of positioning base station transmitters of a
mobile phone network and assigning frequencies to the transmitters, both in an optimal way …

Network coverage and capacity optimization is an important operational task in cellular
networks. The network coverage maximization by adjusting azimuths and tilts of antennas is …

Wireless access to the Internet is expected to be very valuable for both individuals and the
society. However, advances in transmission technology alone may not be sufficient to …

This paper concerns a geometric disk problem motivated by base station placement issues
arising in wireless network design. The problem requires covering a given set of clients by a …

In this paper, discrete mathematical programming approaches are used to solve the
frequency allocation and cell site selection problem in an integrated setup. Both CDMA …

We consider the parameterized problem, whether for a given set D of n disks (of bounded
radius ratio) in the Euclidean plane there exists a set of k non-intersecting disks. For this …

We consider the following optimization problem for UMTS networks: For a specified
teletraffic demand and possible base station locations, choose positions for base stations …

We present the first study on the approximability of geometric versions of the unique
coverage problem and the minimum membership set cover problem. In the former problem …

In this paper we apply a novel meta-heuristic approach, the Coral Reefs Optimization (CRO)
algorithm, to solve a Mobile Network Deployment Problem (MNDP), in which the control of …
