A shoelace-based QoS routing protocol for mobile ad Hoc networks using directional antenna

This paper proposes a new QoS routing protocol for mobile ad hoc network (MANET) using directional antenna. The scheme offers a bandwidth-based routing protocol for QoS support in MANET using the concept of multi-path. Our MAC sub-layer adopts the CDMA-over-TDM A channel model. The QoS on-demand routing protocol determines the end-to-end bandwidth calculation and bandwidth allocation from a source node to a destination node. The paths are combined with multiple cross links, called as shoelace, when the network bandwidth is strictly limited. Due to the directional antenna property, these cross links can simultaneously transmit data without any data interference. This investigation develops a shoelace-based QoS on-demand routing protocol by identifying shoelaces in MANET to more easily construct a QoS route which satisfied the bandwidth requirement. Finally, simulation results demonstrate the better performance in our proposed routing protocol. I.
