Abstract:

The motivation behind this thesis was to find a control allocation algorithm to reduce the power consumption onboard maritime vessels. As more and more maritime operations starts to go at deeper sea levels the further away from the shore the maritime vessels goes. The need to reduce power consumption to be able to operate at a longer time period out in the sea can save maritime businesses for increased costs during missions a deeper sea levels.To reduce power consumption onboard a typical supply vessel used in the North Sea a power efficient control allocation method was designed.

Abstract:

IEEE 802.15.4 is a standard defined for wireless sensor network applications with limited power and relaxed throughput needs. The devices transmit data during two periods: Contention Access Period (CAP) by accessing the channel using CSMA/CA and Contention Free Period (CFP), which consists of Guaranteed Time Slots (GTS) allocated to individual devices by the network coordinator. The GTS is used by devices for cyclic data transmission and the coordinator can allocate GTS to a maximum of only seven devices. In this work, we have proposed two algorithms for an efficient GTS allocation. The first

In this thesis, a resource allocation problem in OFDMA is studied for the energy efficiency of wireless network. The objective is to minimize the total energy consumption which includes transmission energy consumption, and circuit energy consumption at both transmitter and receiver with required per user’s rate constraint. For problem solution, a heuristic algorithm with low computational complexity and suboptimal solution is proposed, developed in two steps with an increasing order of complexity.

Energy is increasingly becoming an exclusive commodity in next generation wireless communication systems, where even in legacy systems, the mobile operators operational expenditure is largely attributed to the energy bill. However, as the amount of mobile traffic is expected to double over the next decade as we enter the Next Generation communications era, the need to address energy efficient protocols will be a priority. Therefore, we will need to revisit the design of the mobile network in order to adopt a proactive stance towards reducing the energy consumption of the network. Future emergi

Abstract:

In wireless networks, devices (nodes) are connected by wireless links. An important issue is to set up high quality (high bandwidth) and efficient routing paths when one node wants to send packets to other nodes. Resource allocation is the foundation to guarantee high quality connections. In addition, it is critical to handle void areas in order to set up detour-free paths. Moreover, fast message broadcasting is essential in mobile wireless networks. Thus, my research includes dynamic channel allocation in wireless mesh networks, geographic routing in Ad Hoc networks, and message broadcasting

Abstract Efficient processor allocation and job scheduling algorithms are critical if the full computational power of large-scale multicomputers is to be harnessed effectively. Processor allocation is responsible for selecting the set of processors on which parallel jobs are executed, whereas job scheduling is responsible for determining the order in which the jobs are executed. Many processor allocation strategies have been devised for mesh-connected multicomputers and these can be divided into two main categories: contiguous and non-contiguous. In contiguous allocation, jobs are allocated di

Both energy harvesting and signal-processing processes are during the downlink. The objective is to maximize the sum-rate, subject to the minimum data and harvested energy constraints at the receivers, assuming a fixed time-switching coefficient.

Viewing distributed power allocation as the collection of rational decisions of each user, we make game theoretic problem formulations, devise distributed algorithms and analyze them.

Abstract:

<p>The foundation of OPEC (Organization of Oil Exporting Countries) was laid in the early 1960‟s by the five major oil exporters, Iran, Iraq, Kuwait, Saudi Arabia and Venezuela, in Baghdad, Iraq. OPEC is supposed to allocate its production level among its member countries based on cartel- dominant firm model, for profit maximization.</p>

Abstract:

碩士<br>國立臺灣大學<br>電信工程學研究所<br>104<br>Crowdsourcing has been an emerging technology in social and network science. Existing researches, however, often neglect the underlying tasks selection process of crowd workers, and how it effects the efficiency and tasks quality of a crowdsourcing system. In this thesis, we consider and formulate this fundamental phenomenon as random walks over graphs; Hence, the efficiency and quality are connected to the mean cover time and occupation measure on graphs respectively. We propose the optimal tasks management and recommendation problem, which could be viewed a

Abstract:

碩士<br>國立臺灣大學<br>資訊管理研究所<br>91<br>In a mobile environment, the battery power of mobile devices is precious. An indexing technique provides the selective tuning to reduce the cost of power consumption, that is, a mobile device only listens to necessary channel slots without listening to all slots. The cost parameter, tuning time, is used to measure the efficiency of scheduling indices and data items in the broadcast channel. Intuitively, a mobile user gets satisfied with his submitted query only when he obtained all the data items in the query. Therefore, a query with multiple data it

Abstract:

We consider the problem of allocating resources in large wireless net- works in which multiple information flows must be accommodated. In particular, we seek a method for selecting schedules, routes, and power allocations for networks with terminals capable of user-cooperation at the signal level. To that end, we adopt a general information-theoretic communications model, in which the datarate of a wireless link is purely a function of transmission power, pathloss and interference. We begin by studying the case of resource allocation when only point-to-point links are available. The problem is

It leads the growth of amount and worth of global HNWI. Following the increasing of the amount of HNWI, the issue of family property’s sustainability becomes more important. Our study is focus on long-term investment to investigate the change of portfolio efficient frontier by various asset allocations. We further study the characteristics, returns and the difference of risk of assets to find the best asset allocation p

Abstract:

碩士<br>長庚大學<br>資訊工程研究所<br>92<br>Many future network services must have the assurance of the bandwidth requirement. However the bandwidth is limited in the network. If we do not reallocate the bandwidth of network, it will cause the network efficiency not good. Bandwidth reallocation is a well-known on-line problem in network, and there are many literatures proposed the outstanding strategy in the past, but the performance was not good enough, and sacrificed the service quality. In this paper, we propose a new bandwidth allocation scheme, and develop to bandwidth allocation algorith
