Book excerpt: Integration of the Internet with a Cellular Network, WMAN, WLAN, and MANET presents an exceptional promise by having co-existence of conventional WWANs/WMANs/WLANs with wireless ad hoc networks to provide ubiquitous communication. We call such integrated networks providing internet accessibility for mobile users as heterogeneous multi-hop wireless networks where the Internet and wireless infrastructure such as WLAN access points (APs) and base stations (BSs) constitute the backbone for various emerging wireless networks (e.g., multi-hop WLAN and ad hoc networks). Earlier approaches for the Internet connectivity either provide only unidirectional connectivity for ad hoc hosts or cause high overhead as well as delay for providing full bi-directional connections. In this dissertation, a new protocol is proposed for integrated Internet and ad hoc networks for supporting bi-directional global connectivity for ad hoc hosts. In order to provide efficient mobility management for mobile users in an integrated network, a mobility management protocol called multi-hop cellular IP (MCIP) has been proposed to provide a micro-mobility management framework for heterogeneous multi-hop network. The micro-mobility is achieved by differentiating the local domain from global domain. At the same time, the MCIP protocol extends Mobile IP protocol for providing macro-mobility support between local domains either for single hop MSs or multi-hop MSs. In the MCIP protocol, new location and mobility management approaches are developed for tracking mobile stations, paging, and handoff management. This dissertation also provides a security protocol for integrated Internet and MANET to establish distributed trust relationships amongst mobile infrastructures. This protocol protects communication between two mobile stations against the attacks either from the Internet side or from wireless side. Moreover, a secure macro/micro-mobility protocol (SM 3 P) have been introduced and evaluated for preventing mobility-related attacks either for single-hop MSs or multi-hop MSs. In the proposed SM 3 P, mobile IP security has been extended for supporting macro-mobility across local domains through the process of multi-hop registration and authentication. In a local domain, a certificate-based authentication achieves the effective routing and micro-mobility protection from a range of potential security threats.

Available in PDF, EPUB and Kindle. Book excerpt: One of the main challenges in next generation wireless networks is to integrate heterogeneous wireless technologies to provide seamless connectivity, with guaranteed Quality of Service (QoS), to mobile users "anytime, anywhere and with any device". In this dissertation, we investigate the problem of integrating cellular networks and Wireless Local Area Networks (WLANs) with the multi-hop communication paradigm used in Mobile Ad hoc Networks (MANETs) to exploit all the connectivity alternatives available to different types of Mobile Stations (MSs). We propose an integrated architecture based on three basic functionalities, namely, topology discovery, gateway discovery, and link quality estimation. We combine these three functionalities into an integrated routing mechanism that exploits all connectivity alternatives available in a generic heterogeneous scenario. Then, we provide a simulation-based analysis of our architecture and integrated routing mechanism in different heterogeneous networking scenarios. Our results show improvements in network's capacity and coverage achieved by our architecture as compared to isolated networks. The results also highlight the importance of the link quality estimation in providing QoS to users, as well as indicate that multi-hop links can be exploited in a controlled network configuration, but the QoS in multi-hop routes cannot be always guaranteed. Furthermore, we address the problem of selecting the best connectivity opportunity for a given service type based on the applications' QoS requirements, as well as on the network condition and user mobility profile. We propose the Connectivity opportunity Selection Algorithm (CSA) that allows MSs to select the connectivity opportunity most appropriate for a given type of service and mobility profile. Furthermore, we describe how our proposed selection algorithm can be introduced into the IEEE 802.21 standard for Media Independent Handover services.

Download or read book Heterogeneous Wireless Networks written by Bin Xie and published by VDM Publishing. This book was released on 2007 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous wireless networks (HWNs) provide flexible and diversified wireless network access (e.g., cellular, IEEE 802.11) by integrating cellular networks, wireless LANs, and ad hoc networks with the Internet. It has been emerging as a promising solution to offer a variety of exciting applications, anytime and anywhere. The flexibility and benefits of the HWN, for example, is to extend the service coverage of the existing cellular and WLAN infrastructure, to improve the communication throughput, and reduce packet transmission latency, based on availability of different types of radio network in the roaming area (cellular, WLAN, or others). In the study, we answer some fundamental questions in the design and deployment of a HWN. The first is how to effectively operate a mobile terminal in ad hoc mode to access the Internet through a cellular network, WLAN or other underlying wireless access networks. The second is how to design ubiquitous seamless mobility support for a roaming user, allowing ubiquitous and bi-directional Internet accessibility, connectivity, and mobility. Finally, it answers the questions that what is the security threats for a mobile terminal that is operating in the ad hoc mode, and how to provide information confidentiality for a continuously moving mobile terminal.

Available in PDF, EPUB and Kindle. Book excerpt: ?Pub Inc This dissertation adopts a "data-first" approach for improving robustness and security guarantees in wireless communications: it provides solutions for robust data delivery under several threat and failure models associated with diverse network settings. The emphasis is on mitigating risks from exploits that target open-air properties of the wireless media. Two parallel streams of work address dominant data communication and design issues in Wireless Data Networks (WDNs, which include Mobile Ad-hoc and Wireless Mesh Networks) and Wireless Sensor Networks (WSNs). In line with the bottom-up approach in WDNs, the first scenario evaluated is survivable architectures for Wireless LANs (WLANs). This forms the basis for designing a broad Traffic Splitting Paradigm (TSP) at the Network layer for Mobile Ad-hoc and Wireless Mesh networks. Under TSP, mesh and ad-hoc nodes split and simultaneously schedule their traffic through multiple available routes to the destination. This dissertation is the first to use simultaneous activation of multiple paths. A mesh node can connect to multiple mesh routers over multiple wireless hops. If the mesh routers are connected together via a backbone network, then a node's traffic to the distribution system can be split across several paths to connected routers and a low cost reassembly of this traffic can be performed at the distribution system. This shifts the bottleneck from the wireless medium to the distribution system. To validate the efficacy of the traffic splitting protocol (TSP) from security and robustness viewpoints, a unique approach emulating adversarial behavior is adopted. In this approach, attacks are launched against both traffic splitting and single path protocols and the success probabilities for such attacks are compared. It is demonstrated that traffic splitting paradigms are provably resilient to jamming, blocking, node isolation, and network partition-type attacks. The broad term "Trust" is loosely coined to model selfish and greedy adversarial behavior as well as ambient network conditions like channel congestion that are detrimental to wireless networks performance. A trust-based environment aware routing scheme dynamically schedules traffic across several available routes in response to changing route conditions. A variant of the Trust Model is also used as basis for key establishment and key management decisions in the network if the network uses encryption protocols. Under current schemes, keys are established with a node as long as it has not been declared malicious previously. The TSP is limited in its effectiveness by the conventional CSMA/CA protocol at the MAC layer. IEEE 802.11 forces nodes to contend for channel access, promoting selfish behavior. For a node to successfully split and effectively schedule traffic through its neighbors, a contention avoiding cooperative MAC would be necessary. Multi-hop Wireless MAC (MWMAC) protocol is developed for this purpose. Under MWMAC, neighboring nodes schedule transmission intervals cooperatively and this reduces channel contention. The second stream of research is in the wireless sensor domain. Misaggregation and unaccounted data loss are amongst the most critical open problems in WSNs: it is hard to distinguish them from in-network-processing and passive participation, which are genuine techniques used for reducing communication and computation overhead. Here, a framework based on sampling-theory and cryptographic-techniques and comprising of non-interactive proofs and proxy reports is developed to bound the error margins in reported values and enable the Base Stations to detect outliers and potential cheating by aggregator nodes. The framework is marked by its simplicity and practical usability: all verification and error checking by the BS are performed in a single round of communication. The validation of the schemes presented in this dissertation is performed by a combined approach consisting of simulations, proof of concepts and theoretical evaluations and comparing their performance with existing techniques. It is deduced that some of these schemes may entail slight overheads in terms of network performance, but are beneficial in the enhanced security and robustness they provide. An attempt is made to integrate security into the protocol architectures themselves, thereby providing a composite framework of proactive and reactive schemes.

This book was released on 2006 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid growth in wireless networks has resulted in a growing need for fast and ubiquitous connectivity. Most networks deployed currently are single hop access point (AP) networks, where the end user is connected to an AP if it is within communication range of the AP. While such networks are popular and have been deployed extensively, the inherent low range of Wi-Fi networks limits their coverage. Again, high deployment costs of high speed wired networks do not allow single hop networks to provide ubiquitous and cheap connectivity. Recently, a highly viable solution to the above problem has appeared in the form of multihop infrastructure networks (MINs). A MIN is a network of wireless routers connected to an AP and provides multihop coverage in an area. These networks may present a highly viable and cheap alternative to the problem of universal coverage. While the concept of MINs is exciting, deployment of such networks cannot commence without a thorough inspection of the performance, handoffs mechanisms and security considerations involved. The aim of this thesis is to provide a complete architecture for MINs and explore the various aspects that affect the performance and security of such networks. We solve the problem in a number of phases. First, we provide an analytical framework using which the end-to-end delay and throughput characteristics of the network can be predicted. This framework can then be used to predict the scalability of such networks. The model can also be used for bottleneck determination in such networks and to provide effective routing techniques. The behavior of the delay characteristics of MINs have been effectively addressed by taking both bulk traffic and single arrival traffic into consideration. The queue modeling for forwarder nodes in MINs is complicated by the fact that traditional queuing mechanisms are no longer valid as the arrival and departure processes can never be simultaneous. We propose two different approaches to queuing analysis in MINs. Secondly, we propose to provide an architecture for handoffs in MINs. This involves defining a handoff for MINs, and outlining a method to perform handoffs depending on the parameters that need to be optimized. The suggested protocols should also aim towards minimizing the delays and message overheads involved in the handoff process. Protocols have also been proposed to reduce the delay and message overheads involved in handoffs by the use of pre-authentication mechanisms. Finally, we propose a security architecture for MINs. The first part of this security architecture addresses the problem of key distribution for group communication. The second part of the security architecture allows communication between the members of a MIN by the establishment of robust key agreement protocols for node-to-node pair wise communication. These protocols can be used for ad-hoc network communication as well.
