This book was released on 2014-04-30 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines concepts for wireless communication in large-scale, dense mesh networks, which can be used in future for plant control or building automation. It is shown that recent communication approaches for resource-constrained, IEEE 802.15.4 hardware do not scale well. This motivates the development of methodologies and protocols for reliable wireless communication in large-scale networks. This work covers the following topics: a “toolbox” for the development, programming, testing, and simulation of communication protocols for embedded systems; the decomposition of large networks into smaller subnets; concepts for scalable broadcasting and routing; the realization of selected network services such as emergency shutdowns and software updates.

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: ABSTRACT: Wireless networks play a significant role in communication systems because of the advantages of flexible access and relatively low deployment cost. Among various wireless networks classified according to structures, wireless ad hoc networks and wireless sensor networks share the same feature of no infrastructure. Although the two types of wireless networks offer a variety of applications in military, civil and research areas, they also pose many unique challenging issues. Due to the shared wireless medium, fragile wireless links, constrained power resource, limited computation capability and dynamic topologies, delay bounded reliable packet delivery from a source to the destination is a tough problem in both wireless ad hoc networks and wireless sensor networks. In this dissertation, we attempt to address some methods to solve some routing problems in mobile ad hoc network (MANET), and wireless sensor networks (WSN).

Book excerpt: Position-based routing was originally developed for packet radio networks in the 1980s [6]. It received renewed interest during the last few years as a method for routing in mobile wireless ad hoc and sensor networks [1, 2, 4]. The general idea of is to select the next hop based on position information such that the packet is forwarded in the geographical direction of the destination. Position-based routing can be divided into two main components: the location service and position-based forwarding. The location service [5, 13] is used for mapping the unique identifier (for example an IP address) of a node to its geographical position. In mobile ad hoc networks, providing accurate location service for position based routing, with low communication overhead, appears to be more difficult task than routing itself [13]. In case of sensor networks, however, destination is a sink or base station whose position is made available to source sensors by flooding. Position-based forwarding is performed by a node to select one of its neighbors as the next hop the packet should be forwarded to. Usually, the following information is required for the forwarding decision: the node's own geographical position, the position of all neighbors within transmission range and the position of the destination. Based on this information, the forwarding node selects one of its neighbors as the next hop such that the packet makes progress toward the geographical position of the destination.
