Available in PDF, EPUB and Kindle. Book excerpt: Mobile ad hoc networks (MANETs) are self-organizing, infrastructureless networks that provide flexibility and convenience in setting up a dynamic network. Since the 1970's, MANETs have attracted a great deal of research aimed at improving their basic performance. However, with the development of real-time applications, incorporating Quality of Service (QoS) into the network architecture becomes essential. Supporting QoS in MANETs necessitates more harmonious collaboration among all network layers, requiring a design that supports cross-layer interactions rather than a traditional independent layered network architecture. The work described in this book enables this goal by proposing a general architecture that supports cross-layer interactions, as well as by designing protocols at several layers of the stack that can exploit this cross-layer information to improve the QoS performance. This book is addressed to professionals in wireless networks, especially those interested in protocol design for supporting QoS in MANETs.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad hoc Networks (MANETs) are re-emerging as a popular networking facility for wireless device users. A growing number of diversified applications are now accessible via wireless devices. The different applications may have different Quality of Service (QoS) requirements, which may better be satisfied by using different routing methods or metric types. Existing ad hoc network routing solutions do not consider various application-level requirements when making a routing decision. They typically make routing decisions based upon limited information acquired at the network layer. Most of the existing routing protocols make use of a single routing metric. Using a single metric type and/or information, only acquired at the network layer may not be able to accommodate different QoS requirements, imposed by diversified user-level applications or application-level data types. The aim of this thesis is to design an efficient routing function for ad hoc networks while at the same time satisfying users" and/or applications" QoS and security requirements. To achieve this, the thesis investigates and specifies routing requirements that could best support application-level QoS and security requirements in MANETs. It also investigates and critically analyses the state of the art in MANET routing, and the mechanisms used for protecting the routing functions. To overcome the weaknesses and advance the state of the art in MANET routing, this thesis proposes two major solutions. The first solution is the Secure ETX (SETX) routing protocol. It is a secure routing solution that can provide routing functions efficiently in malicious MANET environment. The SETX protocol provides a security mechanism to counter black hole attacks in MANETs on the ETX metric acquisition process. Simulation studies have been carried out and discussed in the thesis. Simulation results show that the SETX protocol can provide a marked improvement in network performances in the presence of black hole attacks, and it can do so with a negligible level of additional overhead. The second solution is a novel routing decision making called the Flexible Routing Decision (FRD) framework. The FRD framework supports routing decision making by using multiple metric types (i.e. multi-criteria routing decision making) and uses a cross-layer approach to support application-level QoS requirements. This allows users to use different routing metrics types, making the most appropriate routing decision for a given application. To accommodate the diversified application-level QoS requirements, multiple routing metric types have been identified and interpreted in the FRD framework design. The FRD framework has overcome some weaknesses exhibited by existing single metric routing decision making, used in MANETs. The performance of a routing decision making of FRD is also evaluated using NS2 simulation package. Simulation results demonstrate that the FRD framework outperforms the existing routing decision making methods.

Download or read book Cross layer Design for Mobile Ad Hoc Unmanned Aerial Vehicle Communication Networks written by Abdel Ilah Nour Alshbatat and published by . This book was released on 2010 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad-Hoc network (MANET) in a popular type of wireless network that is formed by a collection of mobile nodes. Each node in such a network has the capability to communicate with its neighbors and non-neighbors through a wireless medium without using any existing network infrastructure. Due to the lack of infrastructure, all nodes in Ad-Hoc network are designed to act as an end system and a router for other nodes. Traditionally, the dominant design methodology for network protocols was based on the open systems interconnection (OSI) reference model. This methodology divided the stack into seven layers in which each layer operates independently. Due to the dynamics of the Unmanned Aerial Vehicle (UAV) Ad-Hoc network, the conventional protocol stack is not sufficiently flexible to achieve certain quality of services (QoS) required by some applications. To overcome the limitations of the layering technique, cross-layering approach was implemented in this dissertation to adjust some key parameters in the first three layers of the OSI model based on the aircraft attitude variations (pitch, roll and yaw) and the variation of wireless links. To that respect, directional antennas were used by the UAVs to extend the coverage area and reduce the number of hops between the source and destination. Meanwhile, since the traditional Medium Access Control (MAC) protocol assumed the use of Omni-directional antennas, we designed a new MAC scheme that adapts its parameters based on the channel Bit-Error-Rate (BER) which is affected by the new antenna system and aircraft attitude. As for the routing protocol, we modified the Optimized Link State Routing (OLSR) protocol in such a way that the decision for selecting the route will be based on a local profile that holds the gathered information form the first three layers. UAV Ad-Hoc network was implemented by using a discrete event simulator called Optimized Network Engineering Tool (OPNET). We investigated the performance of the proposed techniques and compared them with the existing schemes. The simulation results showed that the proposed techniques improved the network performance and gave results better than the existing protocols in terms of throughput and End-toEnd delay.

Available in PDF, EPUB and Kindle. Book excerpt: This book surveys state-of-the-art optimization modeling for design, analysis, and management of wireless networks, such as cellular and wireless local area networks (LANs), and the services they deliver. The past two decades have seen a tremendous growth in the deployment and use of wireless networks. The current-generation wireless systems can provide mobile users with high-speed data services at rates substantially higher than those of the previous generation. As a result, the demand for mobile information services with high reliability, fast response times, and ubiquitous connectivity continues to increase rapidly. The optimization of system performance has become critically important both in terms of practical utility and commercial viability, and presents a rich area for research. In the editors' previous work on traditional wired networks, we have observed that designing low cost, survivable telecommunication networks involves extremely complicated processes. Commercial products available to help with this task typically have been based on simulation and/or proprietary heuristics. As demonstrated in this book, however, mathematical programming deserves a prominent place in the designer's toolkit. Convenient modeling languages and powerful optimization solvers have greatly facilitated the implementation of mathematical programming theory into the practice of commercial network design. These points are equally relevant and applicable in today’s world of wireless network technology and design. But there are new issues as well: many wireless network design decisions, such as routing and facility/element location, must be dealt with in innovative ways that are unique and distinct from wired (fiber optic) networks. The book specifically treats the recent research and the use of modeling languages and network optimization techniques that are playing particularly important and distinctive roles in the wireless domain.
