Environmental Monitoring via Mobile Sensors and Improving Energy Efficiency by RAF

Wireless sensor networks have been a big promise during the last few years, but a lack of real applications makes difficult the establishment of this technology. Monitoring the environment in collection and sending data is considered to be a ridiculous task. To solve this problem, RAF based Energy Efficient Routing and Environment Monitoring via Mobile Sensors is proposed in Mobile Wireless Sensor Networks. In RAF-EERM, the relay node is elected according to the Relay Aware Factor. The Relay Aware Factor is estimated by knowledge of link weight and residual energy. The relay factor helps in monitoring the environment and keeps on updating the weather conditions of the environment. The experimental results prove that RAFEERM increases in packet delivery rate, reduces both delay and energy consumption, prolongs the function lifetime and guarantees high Quality of Service in WSN.
