Utility-based bandwidth allocation algorithm for heterogeneous wireless networks

Utility-oriented adaptive QoS and bandwidth allocation in wireless networks

In this paper we propose a general utility-oriented adaptive Quality of Service (QoS) model for wireless networks and establish a framework for formulating the bandwidth allocation problem for users with timevarying links. For slow link variations, it is inadequate to only employ lowlevel adaptive mechanisms at the symbol or packet level, such as error correction coding or swapping packet trans...

Jointly power and bandwidth allocation for a heterogeneous satellite network

Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...

Efficient Utility-Based Bandwidth Allocation Scheme for Multi-traffic Distribution in Heterogeneous Networks

Utility-based Adaptive Bandwidth Allocation for Multi-Class Traffic in Wireless Networks

Adaptive bandwidth allocation is becoming more attractive in wireless communications since it can dynamically upgrade or degrade the allocated bandwidth of ongoing calls to cope with the network resource fluctuation. In this paper, we propose a utility-based adaptive bandwidth allocation scheme for multi-class traffic in wireless networks. Our scheme allocates bandwidth to ongoing calls accordi...

An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
