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 ...

It has become feasible to stream video across a mobile network ad hoc network (MANET). This paper proposes using the H.264 codec's 'redundant frames' video delivery over multi-paths and compares their performance to Video Redundancy Coding, another ...

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 ...

This paper proposes CLUSMA: a middleware framework for communication between sensor nodes in Wireless sensor network. Our proposed technique is based on clustering technique (CLUS) and it uses Mobile Agent (MA). This paper gives a sketch of the ...

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, ...

A network layer perspective of quantifying the achievable throughput in communication networks is presented; the goal of which is to provide an upper bound on end-to-end throughput by taking into account the bursty nature and delay requirements of real ...

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 ...

Ubiquitous access to information and services anywhere, anytime and anyhow at low cost is one of the essential features of future mobile communication networks, which will interconnect a heterogeneity of various systems and be much more dynamic and ...

In order to avoid that data transfers adversely influence each other, or at least take such knowledge into account, Grid applications should be aware of the network topology. We present a simple tool which measures and provides this information and show ...

The complexity of technical systems in automation is rapidly growing and is causing increasing costs. Research has to identify appropriate measures to deal with the increasing complexity; Artificial Intelligence (AI) and Cognitive Science (CS) already ...

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 ...

Traditional wireless networks are characterized by fixed spectrum assignment policy where a new approach is cognitive radio networks. In a cognitive radio paradigm we opportunistically sense the spectrum and utilize the part of the spectrum which is ...

Handoff (HO) call queuing can be successfully employed to ensure better Quality of Service (QoS) guarantees in mobile cellular networks. In this paper, we present the performance analysis of prioritized and non prioritized HO call queuing schemes in ...

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 ...

In this paper, we have proposed and developed a Poultry Farm Monitoring System based on Wireless Sensor Network (WSN) using Crossbow's TelosB motes integrated with commercial sensors capable of measuring temperature and humidity values. The data ...

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 ...
