Abstract
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..
