| In cellular wireless communication systems, transmitted power is regulated to provide each user an acceptable connection while limiting the interference seen by other users. Previous work has focused on maximizing the minimum carrier to interference ratio (CIR) or attaining a common CIR over all radio links. However, previous work has assumed the assignment of mobiles to base stations is know...

The rapid development of mobile communications has caused a higher demand of radio channel or carrier frequency due to additional mobile subscribers. With a limited frequency bandwidth allocated to mobile operators, good network planning is important to avoid congestion in the network. Some of the methods used to improve congestion in mobile networks is cell splitting and frequency reuse, but w...

We present an algorithm that jointly determines the optimal downlink beamformers and the optimal assignment of each mobile to a base station. The optimality criterion is based on a systems perspective; provide sufficient quality of service for all users, transmitting as little excess power as possible. Since the algorithm is centralized and requires knowledge about all the channels in the syste...

This paper addresses the issue of passenger waiting and being stored at a station platform, from which point they plan to board route services towards egress stations. Route services are operated using dedicated vehicles of limited capacity. Each route service has a specific set of downstream egress stations and is operated at given frequency using homogeneous vehicles of limited available capa...

Heterogeneous network (HetNet) consisting of many small base stations (SBSs) within a present macro base station (MBS) is considered. The impact of SBS power on/off is discussed on network power consumption, throughput, and handover, and also the decentralized dynamic channel assignment. Keywords— heterogeneous network; power on/off; handover; throughput; channel assignment

The fleet assignment model (FAM) for an airline assigns fleet types to the set of flight legs that satisfies a variety of constraints and minimizes the cost of the assignment. A through connection at a station is a connection between an arrival flight and a departure flight at the station, both of which have the same fleet type assigned to them that ensures that the same plane flies both legs. ...

The number of electric vehicles is increasing rapidly worldwide, leading to demand for charging. This will negatively impact the grid. Therefore, it essential relieve power grid operation pressure by changing charging behaviour users.
