Abstract: 
Recent large scale disasters have awaken governments at home and abroad to their needs for preparedness to support public safety and performance of cyber-systems assisting first responders (FR). First responders of various agencies are often on the frontline to assist in managing these events to protect lives and property. The effectiveness of their mission is highly dependent on capability of mobile wireless systems available at incident scenes, especially how their mobile infrastructure and devices can assist in real-time FR connectivity and location tracking, and protect against threads and vulnerabilities in an integrated manner. 
The talk presents challenges to achieve such integration when taking into account resource limitations in mobile systems, mission-orientation of first responders, and possible threats and safety problems at incident scenes. We will amplify these challenges on two examples: (a) reliable relay placement for FR communication in high-rises, and (b) alert mechanisms if threats are detected. In case of the reliable relay placement, we will examine placement of relays to communicate reliably with base stations via polymorphic networks. In case of alert mechanisms we will discuss solutions such as Mobi-Herald and examine it against resource limitations and possible threats.
We will conclude the talk with a short overview of other research projects that are going on in the Mobile Networking and Operating System (MONET) group at the University of Illinois.
