TRAT: traffic-aware topology control algorithm for energy efficiency in wireless sensor networks

In wireless sensor networks, a number of nodes deployed in dense manner should be self-configured to establish the topology that provides communication and sensing coverage under stringent energy constraints. To establish an efficient topology, we propose the TRaffic-Aware Topology control (TRAT) algorithm that reduces energy consumption by considering the total amount of data flows in the network. Our algorithm controls the number of active nodes and adjusts nodal transmission power with traffic information. According to our results, the proposed algorithm shows about a 30% better performance than other methods in terms of energy efficiency.
