A system-level power saving approach for cellular networks with microcells/picocells
Abbas, Ziaul Haq; Li, Frank Yong (Chapter; Peer reviewed, 2011)Network power consumption reduction has recently become an active research topic. In this paper, we propose a novel approach to save power consumption of a three-cell microcellular network. When the traffic load in the ... -
Analysis of load balancing and interference management in heterogeneous cellular networks
Abbas, Ziaul Haq; Muhammad, Fazal; Lei, Jiao (Journal article; Peer reviewed, 2017)To meet the current cellular capacity demands, proactive offloading is required in heterogeneous cellular networks (HetCNets) comprising of different tiers of base stations (BSs), e.g., small-cell BSs (sBSs) and conventional ... -
A continuous-space analytical approach for relay node placement in hybrid cellular and ad hoc networks
Abbas, Ziaul Haq; Li, Frank Yong (Journal article; Peer reviewed, 2009)A hybrid network is composed of a cellular component and an ad hoc component connected by a relay node, for the purpose of coverage extension and/or capacity improvement. In this paper, we analyze the capacity of such a ... -
A Deep Learning Approach for Energy Efficient Computational Offloading in Mobile Edge Computing
Zaiwar, Ali; Lei, Jiao; Baker, Thar; Abbas, Ghulam; Abbas, Ziaul Haq; Khaf, Sadia (Peer reviewed; Journal article, 2019)Mobile edge computing (MEC) has shown tremendous potential as a means for computationally intensive mobile applications by partially or entirely offloading computations to a nearby server to minimize the energy consumption ... -
Enabling Soft Frequency Reuse and Stienen's Cell Partition in Two-Tier Heterogeneous Networks: Cell Deployment and Coverage Analysis
Abbas, Ziaul Haq; Haroon, Muhammad Sajid; Muhammad, Fazal; Abbas, Ghulam; Li, Frank Young (Peer reviewed; Journal article, 2020)Heterogeneous cellular networks (HetNets) are one of the key enabling technologies for fifth generation (5 G) networks. In HetNets, the use of small base stations (SBSs) inside the coverage area of a macro base station ... -
Energy Efficiency in Hybrid Mobile and Wireless Networks
Abbas, Ziaul Haq (Doctoral dissertations at the University of Agder;49, Doctoral thesis; Peer reviewed, 2012)Wireless Internet access is almost pervasive nowadays, and many types of wireless networks can be used to access the Internet. However, along with this growth, there is an even greater concern about the energy consumption ... -
Power consumption analysis for mobile stations in hybrid relay-assisted wireless networks
Abbas, Ziaul Haq; Li, Frank Yong (Chapter; Peer reviewed, 2010)While Internet access using mobile or wireless technologies has become ubiquitous these days, the energy consumption aspect of such connections has not been studied in-depth yet. In this paper, a hybrid wireless network, ... -
Two teletraffic-based schemes for energy saving in cellular networks with micro-cells
Abbas, Ziaul Haq; Li, Frank Y. (Journal article; Peer reviewed, 2012)The energy consumption of Base Stations (BSs) is known to constitute a major part of the power consumption in a cellular network. In this paper, we propose a novel approach which may switch a BS off under light traffic ...
