Although today’s Internet predominantly uses the flat-fee pricing scheme, the need for more sophisticated pricing has grown, especially for domains where bandwidth resources are scarce and expensive. This paper focuses on how to determine the price vector that maximizes the system revenue in priority-based networks. Similar problems have been examined using equilibrium analysis, but the assumpt...

Location-based services (LBS) evolved from mobile service. A mobile service is determined by the interaction of the user, the mobile device, and the mobile provider. Since the value for the users depends on the context (i.e. environmental factors surrounding them), mobile services can be assigned to different context-aware services which are characterized by integrating information about the us...

Network quality of service is traditionally thought to be provided by a combination of scheduling in the network nodes to enforce a capacity sharing policy and traffic controls to prevent congestion that could annihilate that policy. The work presented herein is instead based on an end-to-end argument: A capacity sharing policy is enforced by traffic controls in the hosts at the edges of the ne...

The most remarkable trends in communication have been the huge popularity of Internet and the growth of digital cellular telephony usage. There is a strong demand to combine these two in the form of mobile Internet access. This paper discusses the service implementation issues for the wireless environment. The requirements placed on the services and service development by the mobility are prese...

Over the past ten years location-based services (LBS) have been variously touted as the next generation of GIS; as the killer application that will bring the GIS industry to its next level of prosperity; and as a growing threat to human privacy. This chapter attempts to provide a basic introduction to LBS, and a discussion of some of the major issues surrounding them. It begins with basic defin...
