Distance-related energy consumption analysis for mobile/relay stations in heterogeneous wireless networks
2010
While the availability of more than one mobile or wireless technologies is enhancing the ubiquity of the Internet access, the corresponding energy consumption effects on mobile station battery for connection selection has not been investigated in depth yet. In this paper, a heterogeneous wireless network, which consists of three constituent networks, is studied with respect to the amount of data communicated and the battery operation time. Four alternative hybrid paths for separate uplink and downlink traffic, each involving more than one network, are analyzed with respect to energy consumption aspects of the mobile (and relay) station. The energy in these paths is analyzed mainly by consid…
Service Provisioning and User Association for Heterogeneous Wireless Railway Networks
2017
In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
Joint Dynamic Resource Allocation for Coupled Heterogeneous Wireless Networks Based on Hopfield Neural Networks
2008
This paper proposes an algorithm to solve the problem of Joint Dynamic Resource Allocation in heterogeneous wireless networks. The algorithm is based on Hopfield Neural Networks to achieve fast and suboptimal solutions. The generic formulation is particularized and evaluated in an HSDPA and 802.11e WLAN coupled networks. Some illustrative simulations results are presented to evaluate the performance of the new algorithm as compared with other strategies. The obtained results confirm the validity of the proposal.
