An Efficient Distributed Framework for Adaptive Service Discovery in Mobile Ad-hoc Networks

The key innovation of this work (both Phase I and Phase II) is the design and development of enhanced Adaptive Service Discovery (ASD) Framework to support efficient and reliable service discovery in mobile networks. In general, service discovery in mobile environments is a complex challenge. The lack of infrastructure and unpredictable nodes movements complicate discovery and use of needed services. Furthermore, mobile networks are composed of heterogeneous nodes with different capabilities and limitations and goals, each of which needs to be taken into consideration during service discovery. In addition, discovered services can be very similar to one another and thus mobile nodes are faced with the fact that they need to evaluate and differentiate between available options. All of these issues complicate discovery process and require thoughtful and comprehensive design that takes these characteristic into account and delivers scalable and fault tolerant solution. During Phase II we will enhance peer-to-peer collaboration by protocols allowing nodes to customize service discovery protocol, service advertisement protocol and advertisement caching protocol. Furthermore, we will also design and implement the following framework extensions: support for role-based interactions, support for service composition, support for proactive service discovery and support for adaptive service dissemination.
