In multimedia wireless networks, when a mobile host (MH) moves to a neighbor cell, it requests the base station (BS) to reserve the bandwidth for seamless handoff. The reservation scheme based on the fixed 2-tier cell structure was proposed to prevent the reservation requests from the MHs close to the BSs. In this reservation scheme, the BS requests the reservation only when the MH is outside o...

Inefficient bandwidth sharing in a datacenter network, between different application frameworks, e.g., MapReduce and Spark, can lead to inelastic and skewed usage of link bandwidth and increased completion times for the applications. Existing work, however, either solely focuses on managing computation and storage resources or controlling only sending/receiving rate at hosts. In this paper, we ...

The ability to discover services in Mobile Ad hoc Network (MANET) is a major prerequisite. Cluster basedcross layer intelligent service discovery for MANET (CBISD) is cluster based architecture, caching ofsemantic details of services and intelligent forwarding using network layer mechanisms. The cluster basedarchitecture using semantic knowledge provides scalability and accuracy. Also, the mini...

This paper proposes a Bandwidth Utilization in wavelength-divisionmultiplexed passive optical network (WDM-PON) subject to requirements of fairness, efficiency, and cost. An Optical Line Terminal (OLT)-centric bandwidth allocation model is proposed which employs a credit pooling technique combined with a weighted-share policy to partition the upstream bandwidth among different classes of servic...

Carrying IP tra c over connection-oriented networks requires the use of bandwidth on demand schemes at gateways or network interfaces. A new virtual queue occupancy, which is more accurate than the classical one, is being proposed for IP/SONET bandwidth on demand. Based on the virtual queue occupancy, two enhanced periodic approaches for lossless services, LAVQ and LAVQL, are simulated and eval...

This paper proposes a dynamic bandwidth management algorithm in which more bandwidth is allocated for higher class users and also higher priority is given to the videos with higher popularity within a class using agent technology. The popularity and weight profile of the videos which is used for efficiently allocating bandwidth is periodically updated by a mobile agent. The proposed approach al...

Dynamic bandwidth allocation for VBR video is a critical issue in bandwidth management. While keeping high bandwidth utilization, low complexity and longer effective allocation time are new challenges in future heterogeneous environments due to the mobility of wireless networks. In this paper, a scene-base bandwidth allocation with two-phase scheme (SBATP) is proposed. Desired bandwidth is allo...
