Overhearing based relaying scheme in wireless sensor networks with mobile access points
Hyu-Dae Kim, Dong‐Ho Cho · 2007
In sensor networks with mobile access points (MAs), distant sensor nodes cannot communicate directly with the MA when it is path-constrained and sensor area is very wide. For these nodes, we propose a relaying operation based on overhearing, which is very simple and compatible with the conventional operation of MAs. The simulation results show that it enhances coverage and energy efficiency.
