An experimental study on connectivity and topology control in real multi-hop wireless networks

Topology control by means of transmit power adjustment is a well-studied technique for improving the network capacity and energy efficiency of wireless ad hoc networks. In this paper, we investigate the feasibility of connectivity and topology control in a real IEEE 802.11b testbed composed of inexpensive commercial off-the-shelf (COTS) routers. Although topology control via transmit power adjustment is feasible based on analytical studies and emulations, it is difficult in practice for the range provided by COTS wireless routers.
