Cross-layer selective routing for active access-point minimization in wireless mesh network
I‐Wei Lai, Wen-Chung Kao, Nobuo Funabiki · 2015
A Wireless Internet-access Mesh NETwork (WIM-NET) provides the scalable and reliable internet access through the multiple access points (APs) and wireless relay communications. In particular, by redundantly deploying APs in the network field, the WIMNET becomes robust to the link or AP failure. However, these redundant APs increase the power consumption, and thus the number of active APs should be minimized by the selective routing without loss of the transmission performance. In this work, we propose to reinvent such selective routing algorithm by exploiting physical-layer technologies. An exemplar numerical simulation demonstrates that this cross-layer selective routing can further minimize the number of APs, leading to less operational costs in WIMNET.
