Bandwidth balancing in mobile ad hoc networks

In this paper, we extends bandwidth balancing technique in wired networks to operate in mobile ad hoc networks (MANETs). In bandwidth balancing in Distributed-Queue-Dual-Bus (DQDB), different nodes occupy the same channel, and information about the bandwidth is transferred between nodes in the unused bandwidth. Similarly, in wireless networks, the capacity on a channel is shared by several sources at different nodes and the bandwidth information can be monitored on the shared medium. Using the bandwidth balancing technique, we introduce a flow control scheme for MANETs that limits each flow at each node in a transmission region to take only a fraction of the remaining capacity. Extensive simulations demonstrate that our flow control scheme is effective and can provide Quality of Service (QoS) guarantees for flows in MANETs.
