“…Convolutional Code [8] is an error correction code which, by sliding the into a data stream from Boolean polynomial function and generates parity symbols. The encoder's "convolution" is represented by sliding application over the data, resulting in the term "convolutional coding."…”

In this paper, a SDR model-based concept approach to the implementation of SDR digital communication. The wireless communication systems are a popular prototyping platform. We propose to create a secure, private wireless channel between two SDR (Software Defined Radio) terminals. It is not the safest option to transfer sensitive data wirelessly via the web. We, therefore, offer an alternative short distance use of the internet for the transmission of secured data. We have implemented different modulation and encoding methods and we have compared their performance with Matlab with the main aim of reducing the BER bit error rate. An entire digital communication system is installed and validated via on-air demonstration that includes a transmitter with an encoder and a receiver. For hardware efficiency, synchronization algorithms including offset stage, offset carrier frequency and recovery time are also optimized.

Mobile Ad-hoc Networks (MANETs) is the network of wireless mobile nodes with selforganizing, dynamic network connectivity without any pre-defined infrastructure for wireless communication. Error-less data broadcasting is the major role in MANET transmission. With the salient feature of dynamic topology and the distributed infrastructure, multipath routing is of great interests in MANETs. Multipath routing methods are dependable on adjacent nodes for finding the shortest path that several data packets are fallen to network traffic. Attention on the adjacent nodes can have the end-to-end delay while broadcasting the data packets into other nodes that finish up being fallen to congestion. It will also reduce network throughput and cause the network optimality problem. In this paper, we propose a new link-disjoint multipath routing method to solve the optimization problem in the real-time network environment. Hence, the proposed method is used to choose the shortest path from multiple paths in MANETs. Simulation results proved that the proposed method performs well in the dynamic network environment.INDEX TERMS MANET, multipath routing, shortest path, load balancing.

“…In this, depending on the streaming bandwidth, either TCP or UDP sessions are chosen for transmission through the heterogeneous network [47][48][49][50][51][52][53][54][55][56]. To prevent the loss of packets during the transfer, important data segments are selected using the Forward Error Correction (FEC) methodology [57][58][59][60][61][62][63][64][65] and these are retransmitted.…”

Transmission Algorithm with QoS Considerations for a Sustainable MPEG Streaming Service

With the proliferation of heterogeneous networks, there is a need to provide multimedia stream services in a sustainable manner. It is especially critical to maintain the Quality of Service (QoS) standards. Existing multimedia streaming services have been studied to guarantee QoS on the receiving side. QoS has not been ensured due to the fact that the loss of streaming data to be transmitted has not been considered in network conditions. With an algorithm that considers the QoS and can reduce the overhead of the network, it will be possible to reduce the transmission error and wastage of communication network resources. In this paper, we propose a scheme that improves the reliability of multimedia transmissions by using an adaptive algorithm that switches between UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) based on the size of the data. In addition, we present a method that retransmits essential portions of the multimedia data, thus improving transmission efficiency. We simulate an MPEG (Moving Picture Experts Group) stream service and evaluate the performance of the proposed adaptive MPEG stream service.
