In a multi-hop network, the throughput is essentially important for real-time applications due to their high bit rate requirement. We investigate the performance of multimedia applications in wireless networks and the impact of various error control protocols. In particular, we propose a two stage error control scheme that improves the effective throughout of wireless networks. We apply error c...

The paper proposes an all-optical 1×M router architecture based on pulse-positionmodulation header processing (PPM-HP) scheme for packet routing in all-optical highspeed wavelength division multiplexing (WDM) packet switching network. The router is mainly comprised of all-optical clock extraction, pulse-position-modulation header extraction, continuous-wave (CW) sources, wavelength conversion m...

The use of bandwidth constrained links in wireless networks necessitates the use of bandwidth saving header compression schemes. In these schemes, a compressor and a decompressor collaborate to encode bulky IP headers into streamlined compressed headers. Intuitively, the gain from compression is the average compressed header length divided by the uncompressed header size. In this paper, we show...

This paper reports on studies of the effects of the TCP/IP protocol header on the system performance of a spectrally efficient cellular system. Integrated cellular-system and TCP-protocol simulations are used to examine the degradation in the effective data throughput and packet delay due to the header overhead. Performance improvements achievable by header compression are investigated. Simulat...

Packet processing is pipelined. A packet flows through the FPGA and memories. An incoming packet is received by the Input Packet Buffer and passed to the Header Field Extractor. The HFE pushes the body of the packet into the dynamic memory. Meanwhile, it parses its headers and creates a Unified-header and a structure reflecting actual arrangement of the headers. The Unified-header is a fixed st...

With the tremendous growth of network technology, network attackers are also rationally increased to disrupt the activities and hacking the data from the network users by the intruder. To provide the security from the intruder is most important one. Many researchers were proposed a different approach for providing security they does not tackle the problem, it leads an untruthful in the network....

Customer experience is increasingly the differentiator between successful companies and those who struggle. Currently, customer experiences become more dynamic; and they advance with each interaction between the company and a customer. Every customer conversation and any effort to evolve these conversations would be beneficial and should ultimately result in a positive customer experience. The ...
