Efficient allocation of channels for wireless communication in different network scenarios
has become an extremely important topic of recent research. The main challenge lies in the …

Non-overlapping time slots are allocated to a plurality of nodes in a network by a mobile
agent that moves from node to node of the network. At a current node of the network, the …

This paper presents a novel method for solving channel assignment problems (CAPs) in
hexagonal cellular networks with nonhomogeneous demands in a 2-band buffering system …

Wireless communication is one of the fastest growing industry segments today. Many types
of wireless networks are now being used for applications such as personal communication …

With the advent of smarter technologies in cellular networks, often the bands used for lower
versions remain unoccupied. To utilize that, in this work, a new paradigm of cognitive radio …

Terminals of a network are mapped cells. Time slots are allocated to the cells such that the
time slots assigned to a first cell are reused as the time slots assigned to a second cell …

In cellular networks, it is important to determine an optimal channel assignment scheme so
that the available channels, which are considered as “limited” resources in cellular networks …

A segment-graph algorithm is provided for wireless spectrum allocation in cognitive
networks based on the cooperation of the secondary users, which aim to maximize the …

With the advent of smarter technologies in cellular networks, often the bands used for lower
versions remain unoccupied. To utilize that, in this paper, a new paradigm of cognitive radio …

This study proposes a discrete collaborative swarm optimizer (DCCSO) for solving the
resource scheduling problem in mobile cellular networks, which aims to employ minimum …
