Topological routing for Heterogeneous Wireless Sensor Networks

In this research, we propose a protocol to create different logical topologies that consider the same physical network topology for the data routing problem in Heterogeneous Sensor Networks (HSNs). The HSN in question has two types of sensor nodes, called L-Sensors (sensor with Low hardware capabilities) and H-Sensors (sensors with High hardware capabilities). The proposed protocol creates different topologies, each designed to meet different application requirements, and use a fraction of the links between H-sensors. In addition, each topology has a tradeoff between latency and energy consumption during data communication. The simulation results show that our routing algorithm based on different topologies reduces energy consumption compared to a literature protocol.
