碩士 === 崑山科技大學 === 電子工程研究所 === 98 === We propose a Silicon Intellectual Property (SIP), integrated in a Cross-Layer control system, capable of signaling with different protocol layers provides IEEE 802.11 WLAN, IEEE 802.11p VANET, and IEEE 802.16e/j/m MAN multiple wireless technologies novel cross-layer QoS controls. We propose Hierarchical Cross-Layer Control (HCLC) framework for complexity reduction of the whole control system. Based on Lyapunov stability principle, we reuse QoS control SIP in when vertical handover switches among the wireless technologies. The proposed SIP is wrapped with AMBA on-chip bus and we provide embedded Linux driver and middleware for integration to an MAC SoC of NIC cards. Therefore, the MAC SoC with the proposed SIP supports cross-layer QoS conrol. In the verification and algorithm-architecture exploration, we utilize the network simulator (NS-2) for whole HCLC control system realization. Implemented with XILINX Spartan-3 XC3S4000 FPGA, the SIP occupies 11,575 gate count and only 12.5MHz clock is needed to perform the HCLC control such that it consumes only 314 mw to assure both QoS and fairness for different wireless technologies.
