New approach in construction ad hoc and MANET radio networks with impulse ultrawideband radio signals

Abstract

One of the challenges in designing self-organizing networks is scalability of such networks. Increasing the number of subscribers on the network and territory of their location leads to significant increasing of packet delivery time from source to destination nodes. This is because usually packet relay in Ad Hoc and MANET networks is based on “store-and-forward” mechanism where each relay node buffers received packet, performs packet processing at three layers (physical, data link, network) of OSI model, performs a route lookup for this packet and then gets media access for packet transmission to the next hop. All this operations on each hop in the route constitute the total packet transmission delay, especially operation of getting media access.
