碩士 === 國立勤益科技大學 === 電子工程系 === 98 === We propose a new cross-layer QoS routing protocol using discrete distributed topology-control algorithm to improve IEEE 802.15.4 enabled network performance. In our approach, the cluster-mesh-tree (CMT) proposed by Chen and Lin [2] is optimized using a discrete distributed topology-control algorithm (DDTCA). The CMT network is based on star-mesh-clusters, which have the most clusters, increasing the beacon frame collisions and reducing the routing path. We propose an approach for solving these problems called the “discrete topology-control CMT algorithm (DCMT)”, based on the DDTCA algorithm and CMT network. This approach provides a more efficient inter-cluster-mesh link to significantly reduce the DCMT routing path length with our “generalized time-slot leasing approach” (GTSL). We also use simulation results to show that DCMT has better performance than the CMT network.
