(English Abstract) |
The IEEE 802.15.3 Medium Access Control (MAC) protocol is designed to support low power and high data rate Wireless Personal Area Networks (WPANs). It works on a Time Division Multiple Access (TDMA) basis within a piconet, which guarantees interference-free connections. However, the protocol is not efficient for Simultaneously Operating Piconets (SOPs) due to the inter-piconet interference. In the current protocol, SOPs can be linked by the parent/child (P/C) and parent/neighbor (P/N) relationships for interference mitigation. But the throughput is limited because the same superframe is shared by the P/C and P/N piconets. In this paper we propose the Public Channel Time Allocation (Public CTA) which is able to greatly reduce, but not entirely cancel the inter-piconet interference. The proposed scheme can achieve higher throughput in the SOPs. Based on the SOPs of DS-UWB system, the simulation results show that the proposed scheme can effectively support the coexistence of SOPs and it can significantly increase the throughput of the SOPs.
