The use of intelligent optimization systems has been a major topic of research in the last few
years for improving the existing urban infrastructure, the traffic optimization and the mobility …

This paper gravitates on the spectrum channel allocation problem where each compounding
node of a cognitive radio network is assigned a frequency channel for transmission over a …

This paper addresses the application of two different grouping-based algorithms to the so-
called capacitated P-median problem (CPMP). The CPMP is an NP-complete problem, well …

The availability of accurate location information of constituent nodes becomes essential in
many applications of wireless sensor networks. In this context, we focus on anchor-based …

Energy efficiency and environmental performance optimization at the district level are
following an upward trend mostly triggered by minimizing the Global Warming Potential …

In construction projects, the relationship between project cost and duration, which is one of
the main factors of the project, are considered the parameters decision-makers. When a …

In several wireless sensor network applications the availability of accurate nodes' location
information is essential to make collected data meaningful. In this context, estimating the …

This paper proposes the application of a novel meta-heuristic algorithm to the metropolitan
wireless local area network deployment problem. In this problem, the coverage level of the …

In this paper we present a novel grouping harmony search algorithm for the Access Node
Location Problem (ANLP) with different types of concentrators. The ANLP is a NP-hard …

This paper presents the adaptation of a novel heuristic algorithm to the Switch Location
Problem (SLP), a NP-hard problem where a set of distributed terminals, with distinct rate …
