چکیده

The recent advances in telecommunication technology, namely the wireless networks and the Internet, along with the competition of network operators for offering advanced and different services, are putting increasing pressure for building telecommunication software systems that are adaptive to new requirements and easily reconfigurable, even in run time. We show how a new modelling primitive – coordination contract – that we have developed and applied to other applications domains, can provide an effective solution to this problem. We describe coordination contracts and demonstrate, through several examples, how they can support the evolution of requirements of a telecommunications transaction processing system and of the specifications of the Wireless Application Protocol (WAP) Datagram layer. We also outline a development strategy based on coordination contracts that leads to systems that are more agile in reacting to change.

Distributed Group Management in Sensor Networks: Algorithms and Applications to Localization and Tracking

The tradeoff between performance and scalability is a fundamental issue in distributed sensor networks. In this paper, we propose a novel scheme to efficiently organize and utilize network resources for target localization. Motivated by the essential role of geographic proximity in sensing, sensors are organized into geographically local collaborative groups. In a target tracking context, we pr...
