TL;DR: In this paper, the overall network performance for a particular network configuration is characterized by a vector with two components, one representing network coverage and another representing network capacity, which is further weighted by traffic density.
Abstract: Improved techniques for characterizing, adjusting and optimizing the overall performance of a wireless network. In an illustrative embodiment, the overall network performance for a particular network configuration is characterized by a vector with two components, one representing network coverage and another representing network capacity. Network coverage is defined by the likelihood of service under load, including interference, and may be further weighted by traffic density. Network capacity is defined by an amount of traffic with a given spatial distribution that can be served at a given overall target-blocking rate. The overall network performance may be characterized using a two-dimensional capacity/coverage diagram which plots overall network performance vectors, each including a network capacity component and a network coverage component, for various network configurations. The overall network performance may be improved or optimized with respect to a given subset of network parameters by using an algorithm that proposes potential network configurations and evaluates them with respect to their overall network performance.

TL;DR: The proposed approach significantly improves upon a previous method of Sherali et al. (1998) by way of adopting tighter polyhedral relaxations, and more effective partitioning strategies in concert with a maximal spanning tree-based branching variable selection procedure.
Abstract: In this paper, we address the development of a global optimization procedure for the problem of designing a water distribution network, including the case of expanding an already existing system, that satisfies specified flow demands at stated pressure head requirements. The proposed approach significantly improves upon a previous method of Sherali et al. (1998) by way of adopting tighter polyhedral relaxations, and more effective partitioning strategies in concert with a maximal spanning tree-based branching variable selection procedure. Computational experience on three standard test problems from the literature is provided to evaluate the proposed procedure. For all these problems, proven global optimal solutions within a tolerance of 10−4% and/or within 1$ of optimality are obtained. In particular, the two larger instances of the Hanoi and the New York test networks are solved to global optimality for the very first time in the literature. A new real network design test problem based on the Town of Blacksburg Water Distribution System is also offered to be included in the available library of test cases, and related computational results are presented.

TL;DR: In this article, a genetic algorithm is used to identify the best topology of network arcs to collectively meet cost and network reliability considerations, which is shown to be effective, computationally efficient and flexible on a suite of diverse test problems.
Abstract: This paper describes a general approach to the optimal design of communications networks when considering both economics and reliability. The approach uses a genetic algorithm to identify the best topology of network arcs to collectively meet cost and network reliability considerations. This approach is distinct because it is highly flexible and can readily solve many versions of the network design problem, including formulations not previously seen in the literature that more closely reflect actual design scenarios. The method is shown to be effective, computationally efficient and flexible on a suite of diverse test problems.

TL;DR: Computer Networks reveals the guts of what's going on with computers that share data and is neither a user manual nor a technical reference, but provides in-depth background on how network architectures and protocols work.
Abstract: Computer Networks: A Systems Approach, designed for an advanced college-level course in network design and operation, provides the network applications programmer with detailed information about how networks do their thing. While Computer Networks is neither a user manual nor a technical reference, it provides an in-depth background on how network architectures and protocols work. In the beginning, Larry Peterson and Bruce Davie discuss why networks are important and talk about where networks may go in the long term. The authors then move right into a discussion of protocols. There's a fascinating section--complete with plenty of C code--in which the authors actually develop a network protocol called A Simple Protocol (ASP). They compare switching and packet networks and emphasize tunneling protocols. In the internetworking chapter, you'll learn practically all there is to know about Internet Protocol (IP). The concluding chapters talk about traffic management, congestion reduction, and high-speed networking technologies. Computer Networks reveals the guts of what's going on with computers that share data. Though way out of the league of most computer users, true geeks with an interest in networking will find what they need here.
