  7. Some Challenges Future world being more wireless and mobile Complexity and diversity New challenges for architecture and protocol design From top: more demand from the end user (e.g., mobility support) From bottom: emerging technologies (e.g., new abstraction for wireless links) 17 November 2014

  8. Different types Wireless mobile ad hoc Sensor Underwater acoustic Underground Delay/disruption tolerant Aerial and ground vehicular … Different applications Vehicular applications Content-sharing Mobile external sensing Mobile ad-hoc services Emergency applications Mobile social networks … Complexity and Diversity 17 November 2014
