This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Opportunistic networks provide a viable platform for mobile communications due to the ubiquity of smart phones. These networks are characterized by lack of end to-end reliable connections. In such networks, establishing collaboration among nodes is a challenge. In this thesis, a middleware architecture for opportunistic communication and collaboration has been designed, developed, and implemented. The middleware architecture supports a protocol for efficiently exchanging information between mobile nodes during an opportunistic contact. Message formats for differentiating the various kinds of messages that will be transferred across the network are defined to maintain consistency and reduce redundancy. The architecture consists of several modules equipped with system software to differentiate, compute, update and merge information acquired at each participating node. The middleware has been developed with a view to support a variety of application services on opportunistic networks. In particular, the middleware performs service composition utilizing basic services available in different devices. A sample language translation application has been implemented involving several android devices to test service composition in an opportunistic network created among mobile devices. Finally experimental results are carried out to measure success rates of service composition. The experimental studies include results with the following scenarios: parallel service requests; varying service composition lengths; varying content size; varying number of nodes.

Book Synopsis Middleware for Service Provision in Disconnected Mobile Ad Hoc Networks by : Roméo Said
Download or read book Middleware for Service Provision in Disconnected Mobile Ad Hoc Networks written by Roméo Said and published by . This book was released on 2011 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile ad hoc networks (MANETs) are spontaneously formed out of a number of mobile devices that communicate thanks to short-range wireless communication capabilities (e.g. Wi-Fi, Bluetooth). In many ad hoc networks deployed in real conditions, mobile nodes can exhibit highly dynamic behaviors of mobility and volatility. Because of their behavior, the devices in such network environments form so-called "islands" whose topology evolves continuously, rather than a single fully connected network. In this work, I focus on this class of MANETs which I refer to as disconnected MANETs. Network-wide communication in disconnected MANETs is still a challenge, namely because routing techniques designed for fully connected MANETs cannot be applied. The store-carry-and-forward approach provides a solution. With this approach, a message can be stored temporarily on a node, in order to be forwarded later when circumstances permit. Mobility then becomes an advantage as it facilitates message propagation. Messages are therefore forwarded from one network node to another when these nodes have the opportunity to meet. The service-oriented computing (SOC) model seems suited for ad hoc environments because it emphasizes the decoupled nature of its entities. Effectively, the decoupling between a client entity and a provider entity becomes essential in mobile environments with a fluctuating availability of providers, and where end-to-end communications are not guaranteed. Still, in existing service-oriented systems, providers are usually supposed to be always available (e.g. Web services). Providers are also assumed to be continuously reachable in wireless mobile environments, where local connected networks can be created using Wi-Fi hotspots, or by creating ad hoc networks using proximity one-hop or routed multi-hop protocols. Therefore, implementing distributed services for such networks still poses several challenges. Not only network-wide communication features must be provided, in spite of constant network fragmentation, but aspects such as the unpredictable reachability of the providers, or potential communication delays, must be taken into account at the service level. I propose a service platform for mobile nodes that supports the execution of service-oriented applications in disconnected MANETs. The service platform is implemented as a middleware composed of two layers: a communication layer, and a service layer. The communication layer provides mechanisms to decouple two service entities in terms of temporaneous interaction, synchronous behavior, and mutual knowledge. For this layer, I use an opportunistic and content-driven protocol (DoDWAN). The service layer provides mechanisms that decouple service providers and clients in terms of interoperability and service contract. For this layer, I propose solutions for service discovery and invocation. The elements that construct the discovery protocol are the description and advertisement at the provider side, and collection and selection at the client side. Description uses functional and non-functional service properties, as well as context properties. Discovery is based on a peer-to-peer architecture, where a client collects only interesting services. Content-based invocations are used to benefit from the service replication, where a multitude of providers can be offering the same business service. A client creates a functional request according to a discovered provider, then publishes its content-based request message to the attention of all compatible providers. After being satisfied, the client can initiate the healing of residual request and response messages from the network. The healing of response messages can also be initiated by the providers themselves according to the reliability of these responses. Using a prototype implementation of the middleware, I conducted simulations in a disconnected MANET environment. The performances of discovery is directly related to those of the underlying communication layer. Simulations confirm the benefits of content-based invocations in providing faster response times and better client satisfaction. Simulations also show the drastic reduction of redundant and leftover messages when applying the healing mechanisms.

Download or read book Design and Implementation of a Middleware for Ad-hoc Multi-hop Networking on Android written by Tiancheng Zhuang and published by . This book was released on 2012 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently on smartphones, short distance wireless communication between multiple phones mostly relies on existing network infrastructure, which has some limitations and is not flexible enough for many networking scenarios on smartphones. An ad hoc networking support on mobile devices operating system is desired by many mobile application developers. The aim of this thesis is to implement a Java based middleware on Android platform for multi-hop wireless ad-hoc networking over IEEE 802.11. The Ad-hoc On-demand Distance Vector (AODV) [2] is implemented for route discovery and the Reliable User Datagram Protocol (RUDP) [3] is applied for reliable user data delivery. The implementation is developed in the user space of Android system and requires few kernel modifications, so the system can be easily ported to different phone models. The application interface provided by our middleware service is simple and easy to use, so the implementation could be a good underlying ad-hoc networking support for developing Android applications. In this report, the design and implementation of the middleware is presented and experiments have been done to evaluate the routing and throughput performance of the implementation. To verify the correctness and effectiveness of our implementation, a demo file sharing application is developed on top of the middleware.

Book Synopsis Distributed Services in Pervasive Systems by : Sagar A. Tamhane
Download or read book Distributed Services in Pervasive Systems written by Sagar A. Tamhane and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Devices in pervasive systems are generally resource constrained, heterogeneous, personal, and mobile. These constraints limit the services and quality of service offered by the devices. For example, execution of such tasks as video and audio processing might not be possible or successful on cell phones, PDAs and sensors. Hence interactions between devices are exploited to perform collaborative task execution. Devices with better resource levels perform tasks on behalf of other devices. This dissertation provides algorithms for cooperative service executions in pervasive environments. The major contributions of this dissertation are: Cluster Based Scheduling (CBS) algorithm that performs service scheduling in smart spaces. Decentralized Grading Autonomous Selection (DGAS) algorithm that performs fault tolerant service execution in Mobile Ad hoc Networks. Mutual Exclusion for Opportunistic Networks (MEOP) algorithm that facilitates exclusive access to shared resources in opportunistic networks (OPNET). Middleware architecture for devices in OPNETs. An algorithm for performing service composition in OPNETs The main advantages of CBS over existing schemes are - reduced communication and storage overhead, and support for usage of multiple task scheduling algorithms. CBS factors such challenges as device heterogeneity, service availability and device mobility into the scheduling algorithm. DGAS provides fault tolerance by replicating service execution onto multiple devices. Decision about participation of devices in service executions are taken autonomously by each device. DGAS avoids usage of any central entity. When multiple devices need exclusive access to a shared resource, middleware installed on the devices should facilitate the access. MEOP is a token requesting algorithm that provides exclusive access to resources in OPNETs. MEOP has lower communication overhead as compared to token ring, permission based and centralized algorithms. A middleware architecture is proposed for devices in OPNETs. The middleware is modular. Each device can implement any subset of modules. This dissertation also presents service composition algorithms for OPNETs. Analysis of success probability of task execution and the length of compositions is presented and verified. A prototype of the service composition algorithms is implemented on Bluetooth enabled devices carried by students at the University of Texas at Arlington.
