چکیده

The recent technological developments in communication networks have results into a broad range of networks, e.g.,Wi-Fi, Mobile ad-hoc networks(MANET), 3G and other cellular networks, wireless sensor networks, etc. It is envisioned that such diverse networks must cooperate with each other to form cooperative urban networks, for the sake of making use of all the services and resources. Such integration poses great challenges for service discovery, for example, interoperability, robustness, scalability and context-awareness. In this paper, we propose a novel hierarchical architecture to meet the requirements of service discovery in cooperative urban networks, in which we assume various urban networks are connected to overlay infrastructure through cooperative gateway to form cooperative urban networks. We apply hierarchical architecture to urban networks and overlay infrastructure network in order to discover services using optimal service selection algorithm to take into account context-awareness issue. We also compare the performance of our architecture with distributed and centralized architectures.

The Influence of Urban Network Features on the Quality of Traffic Service (RESEARCH NOTE)

The work reported here presents a methodology based on a two-fluid model to assess the degree of influence of various geometric and control features of an urban network on the quality of traffic service. The two-fluid model gives a curvilinear relation between the trip time and stop time per unit distance and its parameters characterize the quality of traffic service in urban networks. Any Chan...

Content Discovery in Mobile Networks Using the Publish-and-Subscribe Paradigm

We present Figaro, a content discovery solution for mobile ad hoc networks. Our main focus is on urban environments, featuring high densities of users in relatively narrow, circumscribed areas where wireless connectivity is provided by an infrastructure (e.g., bus stops integrating a wireless access point). Figaro superimposes an overlay network onto the mobile ad hoc network, exploits the the ...
