The radar range resolution depends on signal bandwidth thereby detection of multiple closely spaced scattered points depends on bandwidth. To resolve this method of pseudo resolution is introduced which exploits the bandwidth allocation and increases the resolution of the overlapping scattered point (target/multipath). This resolution can be achieved by increasing the bandwidth of the received ...

A detailed understanding of the many facets of the Internet’s topological structure is critical for evaluating the performance of networking protocols, for assessing the effectiveness of proposed techniques to protect the network from nefarious intrusions and attacks, or for developing improved designs for resource provisioning. In this way Available bandwidth estimation is a vital component of...

In this paper we study a-priori bandwidth estimation algorithms for TCP flows. An RTT-based bandwidth allocator is proposed, which outperforms a broad class of peak-rate and static allocation flow switching solutions. Our findings suggest that a-priori bandwidth estimation (i.e, before the TCP data transfer phase takes place) is indeed feasible and serves to design simple, yet efficient, dynami...

We consider the fair bandwidth allocation problem of ABR calls by a Connection Admission Controller (CAC) at call setup. Its general solution is given by applying the “max-min fairness allocation policy”. Extensions of this policy take into account the Minimum Cell Rate (MCR) and the Peak Cell Rate (PCR) traffic description parameters, which are essential for ABR. These extensions are distingui...

Due to the success of new multimedia technologies, there is a great interest for providing a resource allocation strategy suitable for multimedia applications. Many solutions proposed in literature are based on proportional share resource allocation, such as WFQ, WF2Q, EEVDF, or SFQ. In a previous paper, we showed how to perform resource reservation according to a Constant Bandwidth allocation....

We present an Adaptive Dynamic Bandwidth Allocation algorithm for Passive Optical Networks. We include results of simulation experiments to show the comparison of its performance with other bandwidth allocation algorithms.

Rex Lee [email protected] Abstract An improved version of stream arbitration based on multiband RF interconnect (MRFI) is proposed. Thanks to the simultaneous multiple channel transmitting/receiving feature of MRFI, dynamic bandwidth allocation is achieved in the proposed arbitration algorithm. With dynamic bandwidth allocation, MRFI based arbitration can guarantee 100% channel bandwidth u...

In this work, we examine the downstream impediments of centralized Ethernet passive optical networks supporting LAN emulation [inter-Optical Network Units communication(ONU)]. The available downstream bandwidth in the centralized scheme is reduced due to LAN emulation and upstream bandwidth allocation functions. The reduction in available downstream bandwidth results in degraded downstream perf...

A flexible bandwidth management scheme namely Bandwidth-based Polling (BBP) for Bluetooth is proposed. A framing structure of time is defined in BBP, and the master allocates proper number of slots for each active slave in a frame. BBP allows the master to poll a slave more than once to achieve high flexibility for bandwidth allocation. The calculation of the polling time as well as the payload...

Encoded video streams present numerous problems in bandwidth allocation, multi-plexing and admission control as a result of their Variable Bit Rate(VBR) characteristics. In particular, since video signals show a large range of variability, peak rate allocation results in very low bandwidth utilization. However, other allocation schemes tend to cause cell loss, delay and delay jitter which make ...
