Communication networks, both wired and wireless, are expected to have a certain level of fault-tolerance capability.These networks are also expected to ensure a graceful degradation in performance when some of the network components fail. Traditional studies on fault tolerance in communication networks, for the most part, make no assumptions regarding the location of node/link faults, i.e., the faulty nodes and links may be close to each other or far from each other. However, in many real life scenarios, there exists a strong spatial correlation among the faulty nodes and links. Such failures are often encountered in disaster situations, e.g., natural calamities or enemy attacks. In presence of such region-based faults, many of traditional network analysis and fault-tolerant metrics, that are valid under non-spatially correlated faults, are no longer applicable. To this effect, the main thrust of this research is design and analysis of robust networks in presence of such region-based faults. One important finding of this research is that if some prior knowledge is available on the maximum size of the region that might be affected due to a region-based fault, this piece of knowledge can be effectively utilized for resource efficient design of networks. It has been shown in this dissertation that in some scenarios, effective utilization of this knowledge may result in substantial saving is transmission power in wireless networks. In this dissertation, the impact of region-based faults on the connectivity of wireless networks has been studied and a new metric, region-based connectivity, is proposed to measure the fault-tolerance capability of a network. In addition, novel metrics, such as the region-based component decomposition number(RBCDN) and region-based largest component size(RBLCS) have been proposed to capture the network state, when a region-based fault disconnects the network. Finally, this dissertation presents efficient resource allocation techniques that ensure tolerance against region-based faults, in distributed file storage networks and data center networks.

Resource allocation in communication and social networks

As networks are playing an increasingly prominent role in different aspects of our lives, there is a growing awareness that improving their performance is of significant importance. In order to enhance performance of networks, it is essential that scarce networking resources be allocated smartly to match the continuously changing network environment. This dissertation focuses on two different kinds of networks - communication and social, and studies resource allocation problems in these networks. The study on communication networks is further divided into different networking technologies - wired and wireless, optical and mobile, airborne and terrestrial. Since nodes in an airborne network (AN) are heterogeneous and mobile, the design of a reliable and robust AN is highly complex. The dissertation studies connectivity and fault-tolerance issues in ANs and proposes algorithms to compute the critical transmission range in fault free, faulty and delay tolerant scenarios. Just as in the case of ANs, power optimization and fault tolerance are important issues in wireless sensor networks (WSN). In a WSN, a tree structure is often used to deliver sensor data to a sink node. In a tree, failure of a node may disconnect the tree. The dissertation investigates the problem of enhancing the fault tolerance capability of data gathering trees in WSN. The advent of OFDM technology provides an opportunity for efficient resource utilization in optical networks and also introduces a set of novel problems, such as routing and spectrum allocation (RSA) problem. This dissertation proves that RSA problem is NP-complete even when the network topology is a chain, and proposes approximation algorithms. In the domain of social networks, the focus of this dissertation is study of influence propagation in presence of active adversaries. In a social network multiple vendors may attempt to influence the nodes in a competitive fashion. This dissertation investigates the scenario where the first vendor has already chosen a set of nodes and the second vendor, with the knowledge of the choice of the first, attempts to identify a smallest set of nodes so that after the influence propagation, the second vendor's market share is larger than the first.

The millennial generation is quickly solidifying its place as the dominate generation within the workforce. As millennials transition through workplace hierarchy it is essential organizations understand how to properly develop incoming talent. This is especially important within sales as the opportunity cost for hiring and developing new sales professionals is much higher compared to other professions. Downward trends in millennial retention rates is also a strong contributing factor to the importance of understanding the millennial generation. This paper aims to identify key concepts and elements employers should incorporate into their sales training programs in order to better develop millennials entering sales roles. Through an analysis of each generation and sales training a clear framework will be identified to achieve this goal. Analyzing millennials unique strengths and weaknesses will provide the basis for the key areas employers need to focus on when designing their sales development programs. The framework identified is easily adaptable within any organizations as the concepts discussed can be universally applied.

The insurance industry consists of financial advisors planning for individual’s financial future through defensive investments that will payout in case of something happening to a person’s greatest asset—themselves. Each financial advisor is mandated to pass a professional exam to receive their license in order to take in clients in each state. There is a process in which clients are serviced and sold on different products of insurance. Advisors need to consider client needs and service them with products are in their best interest and within financial reason. <br/> To sell a product you must have clients, and the way that financial advisor receive clients are generally through two ways: company provided or their own connections. At the end of the day, the goal is to get in front of more people and expand you circle. In that sense, there are two common way people address this expansion of circles and that is build relationships versus networking. The goal of this paper is to dive deep in the insurance industry and analyze the sales process when comparing the difference in selling through building relationships versus selling through networking.<br/> The research plan I have in mind start from researching background and history, to current practices environment, to method process solutions. In the initial stages of my research, I will focus on background and history of the financial services industry in terms of sales and insurance. This will address insurance sales processes in the financial services industry and its features as well as benefits. After explaining the step by step process and potential results of the sales process in the insurance industry, I will start researching current environments of the industry. This will explain the history, key theoretical elements, and significant events of the industry. <br/> The history of the background will set stage for me to address situational challenges in the business based on my own experience to which I will do research to find plausible sales process solutions when comparing relationship sales to networking sales. This research will then be synthesized with my own experimental solutions as I work in the industry, which will help me complete chapter 4 and 5 of my theses – Methods and Execution of Results.
