摘要
Multi-hop packet radio networks with a volatile topology pose significant challenges in the design of scheduling protocols. It is desired that changes in topology do not trigger updates to existing schedules. Topology-transparent scheduling algorithms achieve this objective as they work only with global network parameters, namely the maximum size and maximum nodal degree of the network. In this paper, we present MIMO-TTR+, a topology-transparent scheduling protocol for multi-hop wireless networks with MIMO-enabled transceivers. The protocol uses RTS/CTS handshaking with multiple RTS minislots to utilize the channel bandwidth effectively even when the maximum nodal degree exceeds the number of receive antennas at the destination node. We perform detailed mathematical analysis and numerical simulations to show the superiority of our approach over similar ones in the literature.
