Integrated sensor and RFID network node placement in disaster monitoring applications

Sensors are becoming more popular in many applications with the mission of sending and receiving information from the monitoring environment. However coverage and prolonging the network lifetime are challenging issues in disaster monitoring application. In this paper Sensors and RFID´s are integrated together not only to reduce the cost of deployment but also to reduce the energy consumption and increase the coverage of the monitoring region, four different scenarios are been used and a flooding algorithm was developed to ensure an efficient message broadcast all over the network in order to reduce energy consumption in the network and to have full coverage of the monitoring region.
