In the indoor environments, the geographical routing can perform poorly because it tends to forward messages across the interference (e.g. concrete wall). Nowadays many other 2.4GHz devices (e.g. WLAN or Bluetooth) cause more interferences. Some researchers have proposed the packet-reception-rate (PRR) based geographical routing algorithms [1] [2] [3]. However, these algorithms can incur large overhead and cannot adjust to the interference changes dynamically because they have to send several messages to obtain the PRR. In this paper, we propose an interference-aware geographical routing algorithm for sensor networks (sensor-nets). The proposed algorithm estimates the link qualities fast and energy-efficiently; and selects good-link-quality neighbors accordingly. The proposed algorithm then forwards messages to the node that is closest to the destination among the selected neighbors. The experiment results show that the proposed algorithm achieves higher energy and delivery performances than the previous algorithms.
