| In order to prolong a sensor's operational
lifetime, a main challenge in the field of sensor networks is
energy efficiency. Since much energy is spent for the radio
communication, many approaches exist that put sensor nodes into a
sleep mode with the communication radio turned off. We propose a
new Topology and Energy Control Algorithm called TECA that uses a
very simple clustering approach and connects these clusters in a
very energy-efficient way. Using the concept of virtual links,
passive nodes decide in a distributed way if they should join the
topology and stay active or rather go into a low-powered sleep
mode. Compared to other approaches, TECA establishes a
well-connected topology and is able to save more energy. By means
of simulations, we show that TECA outperforms the two other
approaches in terms of operational lifetime, packet delivery, and
network connectivity. |
