In this paper, we propose a new non-intrusive bandwidth estimation technique for IEEE 802.11 in ad hoc networks using cross layer design. This technique is based on RTS/CTS mechanism and it doesn't generate addition traffic to perform the bandwidth estimation. Initially, it estimates the available bandwidth per node and then evaluates the link's available bandwidth in IEEE 802.11 which plays a vital role in admission control. This technique ensures available bandwidth at MAC layer and it is cross layered to routing layer to set up required link. Routing features discovers QoS routes with enough available bandwidth by QoS routing algorithm at the network layer. Finally, we focus on performance analysis of node based available bandwidth cross layer routing protocol (NBA) and Ad-hoc On Demand Distance Vector Routing (AODV) in adhoc networks. In which, the simulation results show that cross layer routing protocol NBA achieves good throughput and packet delivery ratio and reduces the delay and overhead, compared to AODV.
