Proposed wireless solution WiFi in Disaster and Emergency Response

New System Services Caching Server NAT & Firewall GSM Connectivity Central Database Management System WiFi in Disaster and Emergency Response

Caching Server Concept WiFi in Disaster and Emergency Response

Caching Server Operation WiFi in Disaster and Emergency Response

Caching Server Features Improvement of the response time for Internet objects Optimization of the satellite’s bandwidth usage Authentication for Internet access Bandwidth management Black list implementation Protection to the internal hosts by proxying the traffic WiFi in Disaster and Emergency Response

Caching Server Parameters Hit ratio from 30 to 60% Byte hit ratio from 20 to 50 % Number of users – The less users, the lower efficiency Type of traffic – Cacheable/Non cacheable – Traffic Likelihood Cache size – The bigger cache, the higher hit ratios WiFi in Disaster and Emergency Response

NAT WiFi in Disaster and Emergency Response

Firewall WiFi in Disaster and Emergency Response

GSM Connectivity WiFi in Disaster and Emergency Response SIP server – AXD 320 – Fully functional AXD 320 – MSC – MSC not configured. Outside project scope.

Central Database with LDAP WiFi in Disaster and Emergency Response Facilitation of user administration Services using Central Database for authentication – RADIUS (Network access) – Caching server (Internet access) – Instant Messaging server – FTP server Database searchable with MS Outlook
