| A main challenge in the field of sensor
networks is energy efficiency to prolong the sensor's operational
lifetime. Due to low-cost hardware, nodes' placement or hardware
design, recharging might be impossible. Since most energy is
spent for radio communication, many approaches exist that put
sensor nodes into sleep mode with the communication radio turned
off. In this paper, we propose a new Topology and Energy Control
Algorithm called TECA. We will show the performance of TECA by
means of extensive simulations compared to two other approaches.
In terms of operational lifetime, packet delivery and network
connectivity, TECA shows promising results. Unlike many other
simulations, we use an appropriate link loss model that was
verified in reality. By measuring packet delivery rates, TECA is
able to adapt to different environments while still maintaining
network connectivity. |
