Abstract: | Sensor networks are traditionally built using battery-powered, collaborative devices. These sensor nodes do not rely on dedicated
infrastructure services (e.g., routers) to relay data. Rather, a communal effort is employed where the sensor nodes both generate
data as well as forward data for other nodes. A routing protocol is needed in order for the sensors to determine viable paths
through the network, but routing protocols designed for wired networks and even ad hoc networks are not sufficient given the
energy overhead needed to operate them. We propose an energy-aware routing protocol, based on overlapping swarms of particles,
that offers reliable path selection while reducing the energy consumption for the route selection process. Our particle-based
routing with overlapping swarms for energy-efficiency algorithm shows promise in extending the life of battery-powered networks
while still providing robust routing functionality to maintain network reliability. |
