Regenerative and Adaptive schemes Based on Network Coding for Wireless Relay Network
Recent technological advances in wireless communications offer new
opportunities and challenges for relay network.To enhance system performance,
Demodulate-Network Coding (Dm-NC) scheme has been examined at relay node; it
works directly to De-map the received signals and after that forward the
mixture to the destination. Simulation analysis has been proven that the
performance of Dm-NC has superiority over analog-NC. In addition, the
Quantize-Decode-NC scheme (QDF-NC) has been introduced. The presented
simulation results clearly provide that the QDF-NC perform better than
analog-NC. The toggle between analogNC and QDF-NC is simulated in order to
investigate delay and power consumption reduction at relay node.Comment: 11 pages, 8 figures, International Journal of Computer Networks &

LEVERAGING SOA IN BANKING SYSTEMS INTEGRATION
There is no doubt that the systems integration is one of the most important and complicated tasks in software filed especially for complex applications like banking systems. Complexity in integrating banking systems often comes from continues changes in both technical and business features provided by them to meet customer needs. Banking systems always come from different software vendors which mean using platforms and different design and architecture patterns, and this for sure adds extra complexity for integrating them. Serviceoriented architecture (SOA) is a promising method in software filed that aims to build or restructure software systems in a manner that makes their maintenance and integration easier. Agility is the most important goal that should be achieved when building and integrating banking systems. Simply, agility is needed to meet market needs quickly and efficiently and SOA is the way that could provide itSOA, SOI, P2P Integration, Web Services, and Legacy Code
Relay selection for multiple access relay channel with decode-forward and analog network coding
This paper presents a relay selection for decode-and-forward based on network
coding (DF-NC) and analog-NC protocols in general scheme of cellular network
system. In the propose scheme the two source node simultaneously transmit their
own information to all the relays as well as the destination node, and then, a
single relay i.e. best with a minimum symbol error rate (SER) will be selected
to forward the new version of the received signal. Simulation results show
that, the DF-NC scheme with considerable performance has exactness over
analog-NC scheme. To improve the system performance, optimal power allocation
between the two sources and the best relay is determined based on the
asymptotic SER. By increasing the number of relays node, the optimum power
allocation achieve better performance than asymptotic SER.Comment: 11 pages, 5 figures; International Journal of Distributed and
