This requires that the network is able to offer quality of service (QoS) appropriate for the latency and throughput bounds needed to meet the real time constraint. An important component for QoS provisioning is resource estimation and quality prediction. The paper describes a model-based resource prediction (MBRP) mechanism to support real time communication in multi-hop wireless networks. Specifically, we develop an analytical model for differentiated MAC scheduling protocols. The model can predict per-flow and system-wide throughput and delivery latency, thereby enabling admission control of the flows and providing an efficient network management utility. After describing the basic model, we propose enhanced MBRP (EMBRP) for realistic network environments. Our proposed quality prediction method is beneficial in the deployment of a real ad hoc network where knowledge of resource allocation and consumption is needed to meet the service requirements. Analytical and simulation results show that EMBRP provides accurate flow quality prediction. The results also demonstrate the effectiveness of EMBRP as an admission control solution in multi-hop ad hoc networks.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

The paper shows that controlling the offered load at the sources can eliminate these problems. In addition, we provide an analysis to estimate the optimal offered load that maximizes the throughput of a multi-hop traffic flow. We use this result to devise schemes that can achieve fairness when there are multiple flows from different sources to different destinations. We believe this is the first paper in the literature to provide a quantitative analysis (as opposed to simulation) for the impact of hidden nodes, exposed nodes, and signal capture on sustainable throughput. The analysis is based on the observation that a large-scale 802.11 network with hidden nodes is a network in which the carrier-sensing capability breaks down partially. Its performance is therefore somewhere between a carrier-sensing network and an ALOHA network. Indeed, our analytical closed-form solution has the appearance of the throughput equation of the ALOHA network. Our approach allows one to identify whether the performance of an 802.11 network is hidden-node limited or spatial-reuse limited.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Offices, apartments, and public spaces are or in the near future will be able to deliver information and services to their occupants ranging from instant Internet access to configuration and control in a context dependent, personalized way. Despite progressing internetworking and sophistication, we are still dealing with islands of functionality rather than the invisible computer envisioned by Mark Weiser. We believe that the spread and acceptance of smart environments will depend on common standards as well as a simple and flexible way to access data and devices and compose services from existing ones. A good example of such a system is the World Wide Web, whose success is mainly due to the simplicity with which all kinds of content can be published and referenced. We present an access protocol to bring the Web's simplicity and holistic view on data and services to pervasive systems. Our approach is based on the representational state transfer architectural style and emphasizes abstraction of data and services as resources, interoperation via self describing data and service orchestration with loosely typed components. A particular concern is to provide for functionality in the absence of proxy nodes or infrastructure services like directory servers.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Many algorithms for the fast capacity amplification of the peer-to-peer streaming system have been proposed. However, these algorithms are inefficient in the mobile ad-hoc networks. Topological dynamics of mobile peer-to-peer are exacerbated by the changes of mobile user's location and interest. We observe that the mobile users exhibit correlated mobility patterns in practical ad-hoc networks. We use the stable group algorithm to characterize user mobility in mobile ad-hoc networks. Based on the stable group, we then propose a distributed stable-group differentiated admission control algorithm (SGDAC/sub p2p/), which leads to fast amplifying of the system's total streaming capacity using self-growing. Finally, extensive simulation results are presented to compare between the SGDAC/sub p2p/ and traditional methods to prove the superiority of the algorithm.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.

Shortest paths are usually used to route packets in mobile ad hoc networks (MANET) However, a shortest path may fail quickly, because some of the wireless links on the shortest path may be broken shortly after the path is established due to mobility of mobile nodes. Rediscovering routes can result in substantial data loss and communication overheads. We consider a MANET in the urban environment. We formulate and study two optimization problems related to reliable routing in MANET. In the minimum cost duration-bounded path (MCDBP) routing problem, we seek a minimum cost source to destination path with duration no less than a given threshold. In the maximum duration cost-bounded path (MDCBP) routing problem, we seek a maximum duration source to destination path with cost no greater than a given constraint. We use a waypoint graph to model the working area of a MANET and present an offline algorithm to compute a duration prediction table for the given waypoint graph. An entry in the duration prediction table contains the guaranteed worst-case duration of the corresponding wireless link. We then present an efficient algorithm which computes a minimum cost duration-bounded path, using the information provided in the duration prediction table. We also present an heuristic algorithm for the MDCBP routing problem. Our simulation results show that our mobility prediction based routing algorithms lead to better network throughput and longer average path duration, compared with the shortest path algorithm.","PeriodicalId":150940,"journal":{"name":"2004 IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE Cat.
