Interference-aware topology control for low rate wireless personal area networks

The topology control technique can prolong the network lifetime, but it can suffer the significant performance degradation due to the interferences of WLAN or Bluetooth devices. This paper proposes a novel topology control algorithm to reduce the interference effects. The basic idea of the proposed algorithm is to estimate the interference effects exactly and re-construct the robust network topology to the interference variations. From the experimental results, we can see that the proposed algorithm shows the good performance results in terms of the delivery ratio and the energy consumptions.
