As more and more users become increasingly dependent on wireless and mobile communications, it is necessary to secure a reliable and dependable technology support for "on-demand" services through any of the wireless architectures that have been in development recently, such as mesh networks, WiMax, WiFi, ad hoc networks, sensor networks, vehicular networks, etc.

However, there are serious challenges to overcome, such as the integration of infrastructure-based and ad hoc networks, robust algorithms for self-organizing, reconfigurable wireless networks, on-demand service models and their provision in a highly-volatile interconnection environment, and smooth interoperability of architectures.

WONS, now in its eighth edition, has established itself as a high-quality forum to address these challenges in the context of a workshop that is rich in intense interactions and based on innovative contributions by experts in the field.

This announcement solicits original submissions of high-quality research papers on "wireless on-demand networks" that provide novel insights on protocol and network design, modeling, performance evaluation, pricing and profitability models, QoS models and mechanisms, practical implementations, service level aspects, and Internet integration of wireless networks.

Topics related to all kinds of wireless on-demand networks comprise, but are not limited to:

• Architecture and design
• Evaluation through simulations and experiments
• Modeling
• Integration and co-existence
• Social and economic aspects
• Pervasive and ubiquitous computing
• Localization and mobility management
• Security, privacy, and trust
• Novel applications and services
• Energy-efficient protocols and power management
• Implementations and testbeds
• Opportunistic, delay-tolerant, and dissemination-based protocols
• Future wireless Internet solutions
• Mobile peer-to-peer systems
• Middleware aspects
• Self-X and network management
