In Ultra-Wide Band (UWB) ad hoc networks, admission control and resource management are of major concern. The admission control algorithm helps in resolving infeasible power, reduces the congestion, and guarantees the quality of service (QoS) of unlicensed secondary users. The long acquisition time in the UWB transmissions and the near-sender blocking problems can be resolved by resource management effectively. In this paper, an admission control scheme and the resource management in UWB ad hoc routing is proposed. The bandwidth allocation and the bandwidth redistribution methods are employed here for the call admission control. Initially, bandwidth allocation is done using the HCF Controlled Channel Access (HCCA) centralized access which allows the HC to assign Transmission opportunity (TXOPs) to the ACs by taking into account the specific time constraints of each AC. After allocating the bandwidth, the free bandwidth is allocated to the other stations by estimating the traffic load. The call admission control is employed in order to guarantee the QoS. Simulation results show that the bandwidth allocation and call admission control scheme effectively solves the near-sender blocking problems in UWB ad hoc networks and improves achieved throughput and supports best effort traffic.

Ultra wideband (UWB) is a prospective radio technology for wireless ad-hoc networks. In this paper we propose the Quality of Service (QoS) routing for pulse based UWB ad-hoc network. The performance of TH-UWB on the AWGN channel is studied. The PPM scheme with data rate of 110 Mbps is considered. As the simulation results, the information sent by single-hop transmission has error more than that sent by multihop communication. For the data transmission, TCP is useful for this system. The notion of QoS is a quarantee by network to the best satisfy.

“…Various standards, including Bluetooth [2] and IEEE 802.11 [3], are compatible with MANETs. Ultra Wide Band Radio in MANETs has also been proposed in [4]. MANETs have been applied in environments where there is no wired or cellular infrastructure for example battlefield and disaster recovery scenarios.…”

Using 802.11b as a bearer this paper presents a simple one dimensional mobility model for the evaluation of fall-back communications protocols in medium range point to point communications systems. The technique provides link state data and is based on radio communication between carriages in a lift. Example throughputs for 802.11b are presented. Applications are Ad-hoc networks and in particular machine to machine radio propagation and assessment of link state assess probabilities in ad-hoc.

UWB ad-hoc networks

Abstract: In this paper we propose a new stratem for path selection in a UWB based ad-hoc network which; by minimizing a power-dependent global cost function, can potentially lead to an optimal network organization characterized by low emitted power levels and high network performance.
