Interference Declination For Dynamic Channel Borrowing Scheme In Wireless Networks, Shakil Ahmed, Mohammad Arif Hossain, Mostafa Zaman Chowdhury
Interference Declination For Dynamic Channel Borrowing Scheme In Wireless Networks, Shakil Ahmed, Mohammad Arif Hossain, Mostafa Zaman Chowdhury
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 …
Cooperative Approaches Indicating To Capacity And Power Control For Ad Hoc Wireless Network, Liuju Wu, Maciej Jan Zawodniok
Cooperative Approaches Indicating To Capacity And Power Control For Ad Hoc Wireless Network, Liuju Wu, Maciej Jan Zawodniok
Electrical and Computer Engineering Faculty Research & Creative Works
In this paper, two integrated schemes for fair capacity allocation and power control for ad hoc wireless network are presented. the game theory approach is utilized to derive a collaborative update law. in the practical wireless network, a non-uniform distribution of nodes results in varying degree of interference among the network links or hops. Such varying mutual interference may lead to unfair allocation of bandwidth and result in network congestion. as a result, some links may become bottlenecks for the entire network. Hence, it is important to fairly allocate resources in the entire network. the proposed schemes aim to address …
Dynamic Electrical Ratings And The Economics Of Capacity Factor For Wave Energy Converter Arrays, Fergus Sharkey, Elva Bannon, Michael Conlon, Kevin Gaughan
Dynamic Electrical Ratings And The Economics Of Capacity Factor For Wave Energy Converter Arrays, Fergus Sharkey, Elva Bannon, Michael Conlon, Kevin Gaughan
Conference papers
Wave Energy Converters (WECs) have been in development for several decades with some devices now coming close to commercial realities. As such, pilot projects are being developed, particularly in the UK and Ireland, to deploy WECs on a pre-commercial array scale. The ultimate ambition is to have multiple WECs installed in a ‘wave farm’ in a similar fashion to offshore wind farms. For large scale wind farms the inter-array and export electrical systems can represent more than 20% of the project’s capital expenditure. Submarine power cables account for a large proportion of this cost. The same is expected to hold …
Analysis Of Mimo Communications Systems Based On Experimentally Observed Channels, Pat Chambers
Analysis Of Mimo Communications Systems Based On Experimentally Observed Channels, Pat Chambers
Doctoral
This thesis presents an analysis of multiple-input/multiple-output (MIMO) communications systems where the objective is to provide a unified solution to the problems of (i) crosstalk coupling in transmission line channels (ii) multi-path fading in the time variant high frequency wireless channel. In the case of transmission line channels, a comparative analysis is presented of the performance of MIMO communications systems based on balanced CAT 5 twisted-pair transmission lines, balanced twisted-pair telephone transmission lines scheme as well as unbalanced flat-pair transmission lines. The unbalanced flat-pair transmission lines are viewed as a model for digital subscriber lines (DSLs) which may be deemed …
Adequacy Assessment Of The Irish Generation System Including Wind Capacity, William Carr
Adequacy Assessment Of The Irish Generation System Including Wind Capacity, William Carr
Masters
Adequacy assessment of generation capacity is a statistical measure of the ability of existing or planned generation plant to meet predicted levels of electrical demand. Complications arise in this calculation because at any point in time the exact level of capacity available is variable due to planned and forced outages. Planned outrages is a term used to describe the period during the year when a generation unit is required to be shut down for maintenance work to be carried out. The duration of this outrage is normally known and its timing can be chosen. Forced outages describe the random failure …
