Cost Minimization For Charging Electric Bus Fleets, Daniel Mortensen, Jacob Gunther, Greg Droge, Justin Whitaker
Electrical and Computer Engineering Student Research
Recent attention for reduced carbon emissions has pushed transit authorities to adopt battery electric buses (BEBs). One challenge experienced by BEB users is extended charge times, which create logistical challenges and may force BEBs to charge when energy is more expensive. Furthermore, BEB charging leads to high power demands, which can significantly increase monthly power costs and may push the electrical infrastructure beyond its present capacity, requiring expensive upgrades. This work presents a novel method for minimizing the monthly cost of BEB charging while meeting bus route constraints. This method extends previous work by incorporating a more novel cost model, …

Robust Secure Wireless Powered Miso Cognitive Mobile Edge Computing, Boyang Liu, Jiajia Song, Jin Wang, Haijan Sun, Qun Wang
Electrical and Computer Engineering Student Research
Wireless power transfer (WPT) and cognitive radio (CR) are two promising techniques in designing mobile-edge computing (MEC) systems. In this paper, we study a robust secure wireless powered multiple-input single-output (MISO) cognitive MEC system, which integrates several techniques: physical-layer security, WPT, CR, underlay spectrum sharing and MEC. Three optimization problems are formulated to minimize the total transmission power (TTP) of the primary transmitter (PT) and the secondary base station (SBS) under perfect channel state information (CSI) model, bounded CSI error model and the probabilistic CSI error model, respectively. The formulated problems are nonconvex and hard to solve. Three two-phase iterative …

Non-Orthogonal Multiple Access In A Mmwave Based Iot Wireless System With Swipt, Haijian Sun, Qun Wang, Shakil Ahmed, Rose Qingyang Hu
Non-Orthogonal Multiple Access In A Mmwave Based Iot Wireless System With Swipt, Haijian Sun, Qun Wang, Shakil Ahmed, Rose Qingyang Hu
Electrical and Computer Engineering Student Research
This paper applies non-orthogonal multiple access (NOMA) and relaying schemes in a mmWave based wireless heterogeneous system that aims to support Internet of Things (IoT) applications. The system consists of high power base stations, low-power relays, and low-power IoT devices. Due to the ad hoc deployment nature of low-power relays, they have very limited access to wireline power charging facilities. Furthermore, IoT devices normally have limited power and short battery life. The study assumes low-power relays and IoT devices are capable of energy harvest functionality. With the help of relays or IoT devices, downlink NOMA transmission consists of two phases. …

Adaptive Biasing Cell Association In Ffr Aided Multi-Tier Heterogeneous Networks Under Dynamic Load Variation, Didarul Alam, Tashikur Rahman, Shakil Ahmed, Mostafa Zaman Chowdhury
Electrical and Computer Engineering Student Research
Heterogeneous networks (HetNets) adopting fractional frequency reuse (FFR) improves cell coverage, network capacity, efficiency, assures higher data rates, and better quality of service (QoS) for next generation wireless networks. However they fail to handle dynamic load variation. So we attempt biasing cell association (BCA) to offload user from macrocell to small cell base stations (SCBs) to overcome capacity reduction and throughput degradation. It is based on range expansion of SCBSs by adding a positive bias to the reference signal received power (RSRP). In this paper we propose a FFR aided twin layer HetNet with an adaptive biasing scheme for load …
On Demand Cell Sectoring Based Fractional Frequency Reuse In Wireless Networks, Shakil Ahmed, Mohammad Arif Hossain, Mostafa Zaman Chowdhury
On Demand Cell Sectoring Based Fractional Frequency Reuse In Wireless Networks, Shakil Ahmed, Mohammad Arif Hossain, Mostafa Zaman Chowdhury
Electrical and Computer Engineering Student Research
In this paper, a dynamic channel assigning along with dynamic cell sectoring model has been proposed that focuses on the Fractional Frequency Reuse (FFR) not only for interference mitigation but also for enhancement of overall system capacity in wireless networks. We partition the cells in a cluster into two part named centre user part (CUP) and edge user part (EUP). Instead of huge traffic, there may be unoccupied channels in the EUPs of the cells. These unoccupied channels of the EUPs can assist the excessive number of users if these channels are assigned with proper interference management. If the number …

Class-Based Interference Management In Wireless Networks, Mohammad Arif Hossain, Mostafa Zaman Chowdhury, Shakil Ahmed, Yeong Min Jang
Electrical and Computer Engineering Student Research
Technological advancement has brought revolutionary change in the converged wireless networks. Due to the existence of different types of traffic, provisioning of Quality of Service (QoS) becomes a challenge in the wireless networks. In case of a congested network, resource allocation has emerged as an effective way to provide the excessive users with desirable QoS. Since QoS for non-real-time traffic are not as strict as for real-time traffic, the unoccupied channels of the adjacent cells can be assigned to the non-real-time traffic to retain QoS for real-time traffic. This results in the intensified bandwidth utilization as well as less interference …

Radio Resource Management For Dynamic Channel Borrowing Scheme In Wireless Networks, Mohammad Arif Hossain, Shakil Ahmed, Mostafa Zaman Chowdhury
Electrical and Computer Engineering Student Research
Provisioning of Quality of Service (QoS) is the key concern for Radio Resource Management now-a-days. In this paper, an efficient dynamic channel borrowing architecture has been proposed that ensures better QoS. The proposed scheme lessens the problem of excessive overall call blocking probability without sacrificing bandwidth utilization. If a channel is borrowed from an adjacent cell and causes interference, in that case we also propose architecture that diminishes the interference problem. The numerical results show comparison between the proposed scheme and the conventional scheme before channel borrowing process. The results show a satisfactory performance that are in favor of the …

A New Guard-Band Call Admission Control Policy Based On Acceptance Factor For Wireless Cellular Networks, Asadur Rahman, Mohammad Arif Hossain, Shakil Ahmed, Mostafa Zaman Chowdhury
Electrical and Computer Engineering Student Research
Utilization of limited resources and quality of service (QoS) improvement are the major concerns for wireless communication networks. Excessive call blocking is a constraint to attain the desired QoS. In cellular network, as the traffic arrival rate increases, new call blocking probability (CBP) increases considerably. Paying profound concern, we have proposed a guard-band call admission control policy that reduces the new call blocking probability with approximately steady handover call dropping probability (CDP) that ensures QoS. Our proposed scheme introduces the acceptance factor in specific guard channels where new calls get access according to the acceptance factor. The analytical results prove …

Electrical and Computer Engineering Student Research
In modern days, users in the wireless networks are increasing drastically. It has become the major concern for researchers to manage the maximum users with limited radio resource. Interference is one of the biggest hindrances to reach the goal. In this paper, being deep apprehension of the issue, an efficient dynamic channel borrowing scheme is proposed that ensures better Quality of Service (QoS) with interference declination. We propose that if channels are borrowed from adjacent cells, cell bifurcation will be introduced that ensures interference declination when the borrowed channels have same frequency band. We also propose a scheme that inactivates …
