RouT: A Routing Protocol based on Topologies for Heterogeneous Wireless Sensor Networks

In this work, we propose a routing protocol based on topologies for Heterogeneous Wireless Sensor Networks (HSN) named as RouT. The proposed protocol creates different logical topologies considering the same physical topology of a HSN. The heterogeneous network has two types of sensors nodes, called L-sensors and H-sensors. The L-sensors are nodes with Low hardware capabilities where the H-sensors are sensors with High hardware capabilities. The RouT protocol creates different logical topologies and each topology considers a different number of links among H-sensors. In this way, each topology has its tradeoff between energy consumption and latency during data communication. Simulation results showed that the RouT protocol is able to provide different topologies that can be used if the network application has different requirements.
