Conclusion Chapter 6 variance), it could take infinitely. long for a system to reach steady state. The traditional steady state assumption is therefore worth investigating. The adaptation of this assumption to ad hoc networks also needs to be investigated further. Accounting for topology changes has not been included in the analytical model because it is currently difficult to determine the steady state of an ad hoc network. Further work would involve overcoming this hurdle and incorporating mobility in the analytical model. Routing protocols would then be easily evaluated and optimised. The interference distribution has been modelled as Gaussian in keeping with the results obtained from field trials with cellular CDMA networks. In order to determine whether these estimations and· assumptions are correct, experiments need to be conducted to determine the physical layer attributes of wireless multihop networks. 6-5
