Abstract:
Abstract— One of the goals pursued by this work is to gain a better understanding of the conditions for which spatial reuse in distributed TDMA ad-hoc networks is possible. Such understanding becomes particularly important when considering modern ad hoc networking. With the emergence of software programmable radios that support multiple modes of operations, the effects incurred by operating in low vs high spectral-efficiency mode should be well understood and ideally addressed by the protocol layers if system efficiency is to be preserved. A distributed TDMA system presented in [1] is re-visited to make use of an extended interference model. The extended interference model combines the graph-based interference model with the SINR-based interference model. A description of the cross-layering communication developed between the MAC and the PHY layers to support the model is given. The performance of the TDMA system is evaluated in simulation for both, the graph-based model and the extended model. The effect of the propagation environment (path loss exponent) and of the modulation requirement on spatial slot reuse is studied. Results show that network performance of the graph-based model rapidly degrades as the spectral-efficiency mode increases. The impact is even greater with decreasing values of the path loss exponent. In comparison, the extended model produces good performance results in all operating conditions.
