Now-a-days applications like video distribution of social events, live coverage of sports, e-learning and HDTV have become quite popular. The varying bandwidth needs of these applications have made network resource management a challenge for service ...

Mobile nodes communicate on error prone wireless channel in Mobile Ad Hoc Networks. It is very challenging to provide Quality of Service to data flows due to unpredictable topology and lack of centralized control. Admission Control is a crucial ...

Electronic post compensation of nonlinear phase noise (NLPN) in fiber optical communication is analyzed in this paper. An optimized 16-QAM constellation is proposed to further improve the performance of NLPN compensation in electronic domain.

With the ...

The inability of wavelength conversion between links in All-Optical networks causes congestion and hence results in Packet loss. We have Proposed a GMPLS-Based All-Optical networks that would dynamically locate path for switching in case of congestion, ...

Anycasting is an important service which is used in various networks for its diverse applications. Modeling, optimization and analyzing this important service is an interesting research issue. In this doctoral study we are modeling and analyzing the ...

Perfect functioning not only at hardware level but also at software level design is indispensable to quench the thirst of an ideal real time communication. From software perspective, in the timeless sensitive communication context, Real-Time Operating ...

Multi-Protocol Label Switching (MPLS) is an emerging technology used for the high speed and reliable data transfer, especially in the backbone network. MPLS provides Quality of Service (QoS) routing and Traffic Engineering (TE) mechanism to fulfill the ...

Designing a channel code is always a tradeoff between the complexity of encoder and decoder in conjunction with efficient energy and bandwidth goals. 'Turbo codes' code with mostly high-weight Code Words (hwCW), eventually make the task of the decoder ...

Traffic management in home area networks (HANs) is different from the traditional traffic management in access and core networks. Traditionally HAN traffic works in best effort fashion and the HAN services are usually accommodated on the basis of first-...

In this letter, a combination of 16-state 8-QAM trellis codes with multi-carrier code division multiple access (MC-CDMA) and threshold orthogonality restoring combining (TORC) is introduced over downlink Rayleigh fading channels. In literature, minimum ...

This paper proposes a scheme to provide service mobility with required QoS for different applications in heterogeneous access networks. Some existing schemes and proposed schemes are surveyed and compared with respect to key QoS-related mechanisms and ...

To avoid optical buffering, wavelength conversion has been widely investigated to handle potential burst collisions in the optical domain. The objective of this study is to propose a new scheme to achieve proportional quality-of-service in optical burst ...
