Available in PDF, EPUB and Kindle. Book excerpt: The theoretical performance advantages of dividing a network into independent routing domains is well known; however, the actual benefits are hard to quantify and are often not sufficient to outweigh the added complexity. Justification of domains is especially hard in mobile ad hoc networks (MANETS) because reconfiguration overhead and the use of single interface routers increase. Nevertheless, the authors believe that with the right domain configuration and inter-domain routing protocol, they can get better performance using hierarchical than flat routing, especially in heterogeneous and dynamic networks. This paper proposes a framework for scalable routing in MANETs based on auto-configured optimized routing domains and an enhanced inter-domain routing scheme. To minimize overall overhead, the inter-domain routing protocol exploits existing messages needed for domain maintenance. The framework allows different routing protocols to run in each domain. OPNET simulations show the benefits of the proposed approach using OLSR for intra-domain routing. The results show significant reduction in protocol overhead, increased route stability, and increased route availability in a dynamic heterogeneous network.

Available in PDF, EPUB and Kindle. Book excerpt: While many solutions have been proposed for routing in mobile ad hoc networks, only a few have considered the issue of scalability of these protocols in networks having node membership in the order of thousands spread over a large area. Geographic routing using source-destination locations has been widely suggested as a scalable alternative to conventional routing approaches in mobile ad hoc networks. However, efficient location management algorithms are required to discover a destination's location before data transfer can be attempted using geographic routing. To be deemed scalable with respect to network size, mobility and traffic, the signalling overhead due to location management must be kept low so that the performance of geographic routing is minimally affected. In this research, we introduce a novel location management protocol known as Scalable Location Management (SLALoM), which outlines a scheme for partitioning a given terrain into ordered regions for location management. Our detailed analysis shows that under random node mobility and communication requirements, SLALoM improves upon the asymptotic location management cost compared to existing location management schemes. As an optimization, we use the concept of local forwarding to introduce a scheme called Efficient Location Forwarding (ELF) that mitigates the location update cost of SLALoM. We show that, while the asymptotic overhead cost by such an improvisation matches that of SLALoM, ELF outperforms SLALoM in practice. Noting that a two-level hierarchy leads to an overall reduction in the location management cost, we investigate the use of multilevel hierarchy to further minimize the signalling cost and make efficient use of the limited bandwidth of the wireless channel. We propose a novel grid ordering scheme known as Hierarchical Grid Location Management (HGRID) that yields only a logarithmic increase in the location update cost with respect to the number of nodes in a uniformly and randomly distributed ad hoc network. We also show that, under a specific framework, all the proposed protocols are scalable with respect to mobility and network size. We carry out extensive simulations to quantitatively compare the performance of the protocols under practical considerations that could not be incorporated into the analysis, and to study how location management can affect geographic routing.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

This book was released on 2007 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supporting scalable and efficient routing and service provision in Mobile Ad Hoc Networks (MANET) has been a big research challenge. In this dissertation, we propose a scalable and efficient geographic routing and service provision architecture for MANET. The architecture is designed to possess the features of scalability, efficiency, robustness and adaptability. Conventional topology-based schemes are normally hard to scale, instead, we make use of geographic information in the architecture to improve the performance. Due to the close relationship between routing and service provision, we integrate the application-layer service provision and the network-layer routing in one architecture. Such cross-layer design makes different layers to work more closely and efficiently. The architecture is composed of four components. First, an efficient hierarchical structure is built and maintained. The structure is adaptive and flexible. Specifically, the number of layers can be adjusted according to the service and management requirements. Second, a scalable service and membership management scheme is deployed on top of the hierarchical structure to efficiently track the resource and service states. Third, the traffic patterns in a service provision network are various, and we design unicast and multicast routing protocols to support robust service data delivery in the architecture. We develop two self-adaptive on-demand geographic unicast routing protocols for MANET. They can build efficient paths based on the need of user applications and adapt to various scenarios to provide efficient and reliable routing. The local topology is updated in a timely manner according to network dynamics and traffic demand. A route optimization scheme is adopted to adapt the routing path according to both topology change and actual data traffic requirements. Instead of pre-setting parameter values, each node can determine and adjust the protocol parameter values independently according to different network environments, data traffic conditions and node's own requirements. We use the second protocol to support the peer communications in the architecture. Its reactive and adaptive mechanism can meet different routing requirements in service provision networks. We also design two scalable geographic multicast protocols for MANET to implement scalable membership management and robust multicast packet delivery. The first protocol builds a network-range zone-based bi-directional tree for membership management and packet delivery. In the second protocol, a hierarchical structure is constructed based on an on demand zone structure, and both control messages and data packets are forwarded along efficient tree-shape paths without active tree structure built and maintained, which efficiently reduces the maintenance overhead and increases the reliability of the protocol. Both protocols combine location service for group members with membership management to further reduce overhead. We use the second protocol in the architecture to provide scalable and robust routing support for group communications. Finally, with the support of all the above components, the service provision functions are deployed in the architecture. The service delivery including long-term data transfers and short-term control message transmissions is supported by our unicast and multicast routing protocols. By following the hierarchical structure, we design an efficient and scalable service discovery scheme to quickly locate appropriate service providers. Based on the service states aggregated at different layers through the service management and with the assist of the hierarchical structure, efficient service coordination is implemented in service discovery and usage phases to coordinate multiple service providers to provide a service. Furthermore, robust service monitoring can also be applied in the architecture to monitor the resource and service states during service usage.

Book excerpt: The scalability problem of routing algorithms in Mobile Ad-hoc networks (MANET) has conventionally been addressed by introducing hierarchical architectures, clusters, and neighborhood zones. In all of these approaches, some nodes are assigned different routing related roles than others. Examples include cluster heads, virtual backbones and border nodes. The selection of these nodes on a fixed or dynamic basis adds complexity to the routing algorithm, in addition to placing significant demands on mobility and power consumption of these nodes. Furthermore, the scalability achieved with hierarchical architectures or partitions is limited. This thesis demonstrates that location awareness can greatly aid in MANET routing and proposes an enhancement to location management algorithm used by the Terminodes System. This thesis makes use of geographic packet forwarding, geocasting and virtual home area concepts. It draws from the analogy between ad hoc networks and social networks. The Scalable Wide Area ad hoc network (SWAN), nodes update their location information with a geocast group whose area is given by a well-known function. A source node queries the geocast group of the destination and obtains up to date location information. Then, packets are geographically routed to the destination. The SWAN algorithm also optimizes the control overhead and obtains location information with minimal delay. This thesis also presents the results of our comparative performance study.
