(The final publication is available at link.springer.com) Abstract. Airport baggage sorting stations are the places at which the baggage for each flight accumulates for loading into containers or directly onto the aircraft. In this paper the multi-objective and multi-constraint problem of assigning Baggage Sorting Stations in an Airport is defined and an Evolutionary Algorithm is presented, whi...

Existing base station (BS) assignment methods in mobile networks are mainly driven by radio conditions. This is because it is assumed that the limiting factor in the access network is basically on the air interface. However, a growing concern is that the transport part of the mobile network can also represent a bottleneck. Thus, mechanisms only based on radio conditions may assign a user to a B...

The appropriate assignment of airport resources can greatly affect the quality of service which airlines and airports provide to their customers. Good assignments can help airlines and airports keep to published schedules by minimising changes or delays while waiting for resources to become available. In this paper, we consider a resource allocation problem, namely the problem of assigning avai...

This paper proposes a new allocation method, called the Fixed Cell Assignment, which provides wireless Internet access by employing time division multiple access transmission for the forward link in broadband (10 Mbit/s) wireless networks. The system is configured with directional base station antennas and omnidirectional mobile antennas, with each cell divided into six sectors, and sectors num...

We consider downlink OFDMA in which users are imposed with different proportional-rate constraints, and a base station would like to maximise user rate over subcarrier assignment (SA) and power allocation (PA). To attain the objective, we propose a chunk-based SA and low-complexity PA algorithms. Numerical results show that the proposed SA and PA can provide higher average minimum achievable ra...

In this paper, the performance of smart step closed loop power control (SSPC) algorithm and base station assignment method based on minimizing the transmitter power (BSA-MTP) technique for direct sequence-code division multiple access (DS-CDMA) receiver in a 2D urban environment has been compared. The simulation results indicate that the SSPC algorithm and the BSA-MTP technique can improve the ...

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. Since an exact solution cannot be expected to run in polynomial time for all interesting versions of this problem (they are all NP-hard), our algorithm follows a heuristic approach based on the evolutionary paradigm. F...

a method for solving the descriptor discrete-time linear system is focused. for easily, it is converted to a standard discrete-time linear system by the definition of a derivative state feedback. then partial eigenvalue assignment is used for obtaining state feedback and solving the standard system. in partial eigenvalue assignment, just a part of the open loop spectrum of the standard linear s...

In this paper, we propose a smart step closed-loop power control (SSPC) algorithm and a base station assignment method based on minimizing the transmitter power (BSA-MTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver with frequency-selective Rayleigh fading. This receiver consists of three stages. In the first stage, with constrained least mean squared (CLMS) a...

In this paper an energy efficient TDMA MAC protocol for wireless sensor networks is presented. Wireless sensor networks use battery operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. This protocol uses TDMA to give nodes in the WSN the opportunity to communicate collision free, the network is selforganiz...
