However, one of the main drawbacks has been its per-application deployment (each application using its own SIP stack), leading to narrowly focused development of SIP based services. In this paper, we propose a client-side SIP service and supporting network infrastructure blocks that provide unified mechanisms to execute generic SIP functions. The composition of these building blocks allows for creating richer applications, e.g. a conferencing server coupled with a gaming server provides dynamic conferencing between current occupants of a game room. The main feature of our framework is its availability to all applications including the ones not inherently based on SIP. Also, the SIP service API is designed to be extensible and in addition to providing novel higher level functional primitives like adhoc conferencing and seamless transition of sessions, it also exports a low level interface for specialized applications. Another feature of the service is that it allows a user to plug-in an end device of his/her choice on a per-session basis. We demonstrate the richness of the API by describing prototypes for enhancing various applications as well as new converged applications","PeriodicalId":229045,"journal":{"name":"Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat.

However, a major drawback of those systems is that they largely rely on a tracker server to maintain state information of a horde. Furthermore, if the peer holding all the pieces of a file leaves the system, there is a high probability that the other peers cannot download the entire file. We propose a scalable and highly available P2P multi-source content distribution system called SODON to solve those problems. SODON distributes all the pieces of a file from a seed to a number of carefully selected sub-seeds in order to guarantee a complete set of pieces that are available for a long time. The sub-seeds also work as sub-trackers to maintain the horde state information. As a result, the original tracker server is not overwhelmed by a large population of download requests. Our traces on BitTorrent and simulation result show that SODON is feasible to build, and the sub-seeding and sub-tracking schemes effectively reduce the tracker load while offering a comparatively high availability of shared files","PeriodicalId":229045,"journal":{"name":"Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat.

Various sensor network applications ranging from monitoring to military require sensor nodes to collect data over a continuous time period. The placement, management, and processing of the sensor data necessitates an effective data storage, management and query processing policy. This poster attempts to identify the key query processing techniques in the sensor networks. Design goals and challenges of the query processing techniques are identified. The techniques are evaluated in terms of efficiency, scalability, applicability, and reliability. The evaluation of the techniques is guided by the distinctive query processing features supported by both types of sensor networks, conventional and wide area. Moreover, we argued for the integration of conventional and wide area sensor networks and addressed the integration issues and design goals. In particular, a query processing architecture is proposed to meet the emerging needs of the sensor networks. The architecture addressed the requirements for different layers of the integrated sensor network components such as base stations, sensor nodes, and the workstations in wide area. Additionally, the future research directions for the query processing are outlined","PeriodicalId":229045,"journal":{"name":"Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat.

In particular, single or any source multicast protocols most probably take over resources up to their limits for maintaining multicast tree information. The aim of this paper is to study the possibility and benefit of using multiple shortest paths in order for a new member to reach a multicast tree. Such a mechanism would not reduce the overall amount of state information in the network but it would distribute this amount more evenly among all routers. The idea is to use an alternate shortest path provided by the underlying unicast routing protocol to avoid a saturated router, that is a router that can not or does not want to store any more multicast state information. As the simulation results are very sensitive to the topology used, we have used as input topology a real public Internet map. We have then simulated our multipath-aware join mechanism upon samples of this map. We have found that depending on the tree size, the use of our mechanism can increase successful join attempts by up to 55% when the network is half saturated","PeriodicalId":229045,"journal":{"name":"Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat.

A multitude of devices enable users to communicate everywhere and anytime. One drawback resulting from this ability is the expectation of a caller to always reach the callee. As a consequence the possibility to restrict \"availability for communication\" becomes a necessary feature too. Users demand efficient filtering mechanisms to control incoming calls according to their current context. Communication services should become more user centric and consider context information to adapt to the most suitable behavior. This paper investigates the use of context information to enhance existing SIP call control services and services created with the call processing language (CPL). These context-aware communication services are the proposed approach to cope with the demand for a user centric control of incoming calls. The proposed solutions have been implemented as an extended SIP call control service and an extension to the existing CPL syntax. Currently, location information forms the primary source of context information. Different indoor location sensing systems have been evaluated. Finally, two different kinds of service types have been chosen for evaluation as representatives for the variety of service creation approaches especially in a SIP environment","PeriodicalId":229045,"journal":{"name":"Proceedings. 13th International Conference on Computer Communications and Networks (IEEE Cat.
