A novel link scheduling for special re-use TDMA on ad Hoc networks
Weijie Li · 2014
Special Re-use TDMA (STDMA) emerges as a promising channel access technique for providing Quality of Service (QoS) guarantees in multi-hop ad Hoc networks such as community mesh and sensor networks. The contention-free channel access combined with special reuse of the channel provides significant benefits in the energy/throughput trade-off. However, the protocol may introduce scheduling delay if, on the same path, an outbound link on a router is scheduled to transmit before an inbound link on that router. The total scheduling delay can be quite large since it accumulates at every hop on a path. This paper presents a method to solve this problem to improve the performance of the network system. Compared to the origin STDMA protocol, simulation results present us the superior performance of the proposed algorithm.
