  1. Software Architecture for Mobile Distributed Computing Presented by: Deepak N Lakshminarayanan The University of Texas at Dallas Under the Guidance of Dr. Lawrence Chung

  2. Overview • Survey on Software architecture developed for mobile system, which • Is accessible anywhere • Is accessible anytime • Can tolerate occurrence of disconnection • Can support natural interaction with users • Mobile network is • Highly dynamic in nature • Absence of infrastructure

  3. Goal • To develop mobile system architecture, enabling ambient intelligent vision, i.e. • Consumers will be provided with available content and services immediately • These content and service are provided universally • This should be done at runtime based on specific situation • This mobile system was developed by team headed by Valérie Issarny [Research director, INRIA]

  4. WSAMI – A Middleware Based Web Service • WSAMI supports abstract specification of Ambient Intelligence applications. • When? At run time because of mobile nature • Consumer-oriented application • Built on Web Service architecture – ensures service availability in most environments • Java based prototype. • IEEE 802.11b as its underlying WLAN

  5. WSAMI – MIDDLEWARE ARCHITECTURE • Middleware divided into two parts: • Core Broker • Wireless Container • CSOAP – Resource constraint • Naming and Discovery • Support for connector customization • For QOS

  6. Solutions based on WSAMI • Middleware architecture for Mobile System • Dynamic composition of Mobile Services • Service Discovery Protocol (SDP)

  7. Middleware architecture for Mobile System • Solution based on Web, i.e. Web Service • Reason behind – easily deployable in any environment • Introduced XML-based WSAMI • XML language allows dynamic retrieving of instances • Cost • Language generate security • Language also generates performance • Reduce complexity

  8. Dynamic composition of Mobile Services • Based on Group Management paradigm • Devised a middleware functionality for supporting dynamic composition of mobile services • This solution solves the following issues • Cooperation of nodes • Ensures Trust Management between nodes • Develop distributed application over dynamic, mobile network

  9. Service Discovery Protocol (SDP) • Issue: During design, run time requirement cannot be predicted • For this, Mobile nodes must discover and interact with services available at their vicinity • SDP enables • Nodes to find and use services without network knowledge • Nodes are aware of network environment available at its vicinity

  10. Future Work • As Mobile Computing has a bright future, so does Software Architecture for Mobile Computing 
