Peer-to-Peer networks continue to grow in popularity. However network resource discovery still remains a substantial problem within them. In this paper we will cover some of the more popular current solutions to this problem. We will then propose a mobile agent based solution to allow for dynamic network resource discovery.
Mobile Location-Based Services (LBS) have raised privacy concerns amongst mobile phone users who may need to supply their identity and location information to untrustworthy third parties in order to access these applications. Widespread acceptance of such services may therefore depend on how privacy sensitive information will be handled in order to restore… (More)
In this paper we describe an architecture that supports the secure operation of Location Based Services (LBSs) over the Internet. In particular, we describe a three-party protocol that is used to mutually identify and authenticate users, LBSs, and a trusted middleware infrastructure that is responsible for managing the users' identity and location… (More)
In this paper we describe a sighting blurring algorithm for use by a trusted middleware infrastructure, which is part of an architecture that supports the operation of Location Based Services (LBSs) over the Internet. This infrastructure can only obtain sightings for the users who are directly involved in a current invocation of an LBS. Therefore, our… (More)
