- Ad hoc networks
In this report we study the possible performance of multicast voice type traffic in a multihop ad hoc network, more specifically we assume the medium access control to be TDMA-based. We primarily give a delay estimation, but capacity will be discussed as well. We show that it may very well be possible to handle voice traffic over multiple hops given that the transmission schedule is adapted for it. Time slot length is particularly a very important parameter, and needs to be kept short if voice traffic is to be successful. We also shown that the link capacity rapidly is becoming a limiting factor for larger networks.
