    Performance of the Energy Aware Routing Protocol in Wireless Sensor Networks with mobile nodes
    (International Conference on Wireless Networks (ICWN), 2012) Fote Kamanyi, Antonia; Ngubiri, John; Sansa-Otim, Julianne
    Wireless Sensor Networks (WSNs) are increasing in popularity. This is due to several applications (like car tracking, acute patient monitoring and forest fire detection). Energy in WSNs is a scarce resource and therefore has to be optimized. Several studies on energy aware routing schemes have been made. However, most of them cater for fixed nodes yet in some cases, some WSN nodes are mobile. In this paper, we extend the Energy Aware Routing Protocol (EARP) [1] to cater for WSNs with some mobile nodes. We propose EARP with Mobility Support (EARP-MS) and evaluate its performance. We show that (i) the energy consumed increases as the distance between the source and recipient nodes increase, (ii) providing for node mobility prolongs the WSN lifespan, (iii) mobile nodes have higher residual energy than the static nodes and (iv) the average transmission time is lower when some nodes are mobile..
