Background UNICEF, who focuses on providing assistance to women and children in developing and undeveloped countries, emphasis on helping people in emergency natural disasters. Under the life and death situation, communication is one of the most critical things needed. In order to effectively respond to natural disasters, UNICEF has to select the best type of communication and network at the current time. UNICEF also has to concern about many factors. For example, the local network of the affected area is probably destroyed, and it may not have been reconstructed shortly. The help and sources from local area may not enough. These constraints can be worked on by the communication methods. Assuming that all kinds of power went off,…show more content…
Moreover, the cost of implementing WiMAX is low, yet plentiful bandwidth to limited or nonexistent areas. For its power supply, WiMAX provides sleep mode in order to extend battery life and power efficiency. Tests of WiMAX coupled with WiFi versus satellite systems have been conducted to evaluate the performance. The result showed that satellite had weaker connection, while WiMAX met the expected performance. Nevertheless, a maximum of four users could log onto the network and maintain high quality calls in some circumstances. Fast data rates and extended coverage, flexible allocation of radio signals, low power consumption, data-casting and audio and video streams, and channel switching are all benefits of WiMAX and WiFi which are critical for natural disaster communication (Certain & Liu, 2013). The second type of innovation technologies that should be considered when a natural disaster strikes is called “mesh” which based on solar power. Nilanjan Banerjee, assistant professor of computer science and computer engineering of University of Arkansas told that “The ultimate goal of this project is to save human lives…..Deployment of this system could warn people to get out of harm’s way and could help emergency services personnel reach victims much faster. This last part is critically important because we know that many deaths occur in the minutes and hours after a disaster
