In this paper, we propose a topology-control-based QoS routing (TLQR) protocol, which is a distributed scheme to intelligently establish routes with guaranteed end-to-end bandwidth. That is, we provide a simple residual-hop-count procedure to determine whether a node is capable to accept the new connection request or not. In addition, to enhance the network utilization we incorporate a efficient power adjustment into the route discovery procedure. The simulation results show that the TLQR routing scheme is able to (a) figure out a better route not going through the congestion area in the network, and (b) significantly improve the network performance by adaptively adjusting its transmission power, i.e., achieving better spacial reuse of wireless channel. Thus, we believe that it is a promising way to take the topology control into account while designing a QoS routing protocol in an ad hoc network. |
