Workshopvin7 Virtual Private Ad Hoc Networks

Virtual private ad hoc networks (VPANs) are proposed as a new communication paradigm to address the shortcomings of today's large public networks. VPANs would allow for the formation of secure, self-organizing overlay networks between connected devices according to the user's needs and context. They integrate ad hoc networking techniques to dynamically configure private networks of distributed, mobile nodes. This new approach could support communication within limited scopes like work projects, personal networks of friends and family, or emergency response teams, allowing for easy management of wireless connectivity in different environments.

- 1. Virtual Private Ad Hoc Networks Next-generation network communication
- 2. Current and future evolution 4G communication networks Evolution towards a “network of networks”, es? integrating different technologies (WLAN, enc UMTS, Ad Hoc…) qu nse Private WLAN - WPAN broadband, mobility,C o Characteristics: IP-based, IP-based core Internet heterogeneity Convergence of networking devices and consumer electronics (e.g. cameras, TV…) Public WLAN UGent 2
- 3. Consequences and observations Consequences Connectivity anywhere, at any time and from any device Bigger and bigger (users, devices, services…) Overwhelming, security risks, management… More and more networked devices supporting people in their daily life Observation These large networks do not meet many of the user’s communication needs Communication often takes place within a limited context or scope, e.g. Work related communication: projects, customers, students… Personal communication: friends, family… And thus involves a limited (dynamic, mobile) subset of devices that communicate In a secure fashion In a self-organising and easy to manage way Difficult to setup, configure, maintain and manage E.g. configuration of every separate application, wireless networks… New communication paradigm needed!

- 4. New communication paradigm Trend towards network virtualization: 4G IP network = carrier that provides end-to-end connectivity On top: multiple virtual networks that logically structure the network and its services/resources into small secure communities Deployment of ad hoc techniques Formed when needed according to user needs and context Self-organizing and self-maintaining Dealing with distributed, mobile and dynamic characteristics = VPAN (Virtual Private Ad Hoc Network) UGent 4
