Abstract :
In this paper we evaluate the effects of modulation and coding schemes on the performance of ad hoc networks. The analysis is based on analytical expressions derived for the aggregate information efficiency and the average packet delay in ad hoc networks. Modulation and error correcting coding directly affect the trade-offs involving spectral efficiency, interference immunity and channel reuse in a wireless network. Results of numerical analysis show that lower modulation orders and high coding rates are preferable when one wants to maximize the aggregate information efficiency and minimize the average packet delay.
