Qos Evaluation

The quality of service (QoS) evaluation of heterogeneous networks is an interesting area of research. The traditional QoS evaluation methods usually use a set of network-centric parameters for the performance evaluation of these networks. As a result, using such methods it is not possible to report a comprehensive performance review of networks that would include diverse applications and technologies. To resolve this issue, in this research, a novel approach has been proposed that applies dynamic significance weights and unified metrics of the QoS-related parameters to various applications and technologies present within a heterogeneous network. The result analysis shows that by applying this methodical approach, the performance evaluation of heterogeneous networks can be carried out systematically and efficiently.

As third and fourth generation cellular/wireless networks evolve, operators must learn to efficiently manage diverse services, and multiple networks consisting of varying technologies, cell sizes, and frequency bands. Architectural studies on integrated heterogeneous networks suggest that vertical handovers can be used to increase network efficiency. We propose that carefully-controlled load distribution can also promote Quality of Service (QoS) goals for the diverse services. This study compares session overflow and session placement algorithms in order to determine their effects on efficiency and QoS.

Due to the dynamic nature of Mobile Ad-hoc Networks  (MANETs), the provision of Quality of Service (QoS) guarantees is challenging. The route failure probability in a MANET is increased due to the mobility of nodes, which increases routing overhead. Multi-path routing protocols have relatively greater ability to reduce the routing overheads.  This paper discuses the performance analysis of the Ad-hoc On-Demand Multi-Path Distance Vector (AOMDV) routing protocol. AOMDV is a multi-path extension of a very well known single path routing protocol, (AODV). Extensive simulations were carried out using ns-2.34 and the study concluded that for CBR traffic AOMDV performance degrades as the data packet generation rate increases.

Radio Access

The trend in wireless networks is that several wireless radio access technologies (RATs) coexist in the same area, forming heterogeneous networks in which the users may connect to any of the available RATs. The problem of associating a user to the most suitable RAT, known as network selection problem (NSP), is of capital importance for the satisfaction of the users in these emerging environments. However, also the satisfaction of the operator is important in this scenario. In this work, we propose that a connection may be served by more than one RAT by using multi-RAT terminals. We formulate the NSP with multiple RAT association based on utility functions that take into consideration both user’s satisfaction and provider’s satisfaction. As users are characterized according to their expected quality of service, our results exhaustively analyze the influence of the user’s profile, along with the network topology and the type of applications served.
