This paper proposes a stochastic end-to-end response time analysis of pipelined manufacturing systems based on machine-to-machine communication, where every control message initiating from the first stage is relayed to the next stages along the pipeline. Through the proposed analysis, we can compute the end-to-end response time distribution of each control message, thus provide predictable performance in terms of end-to-end manufacturing times.

In this paper, we propose a new modulation scheme for low power and high performance WBAN in-body communication systems. Simulation results are presented in terms of performance and transmit power. The proposed modulation scheme is more appropriate for high data rate human body applications than other schemes due to the better characteristic of spectral re-growth in the non-linear system environment as well as better performance.

There are descriptions on general high level procedure from IPTV service provider discovery to content selection and acquisition within ITU-T standards. But, we need more specific description to adopt in our domestic standard development. Therefore, we will describe the detail mechanism and metadata for IPTV service provider and service discovery in this paper. We will also describe the considerations on domestic standard development for interoperability between IPTV terminal and IPTV service providers.

As the traffic of the Internet increases and diversifies, the needs for a fast flexible router have made researchers to work on software routers. The existing software router systems may utilize the cluster structure of multiple machines or GPU systems. Especially, Packet Shader, which uses GPU to exploit GPU's extensive parallelism, shows higher performance compared to other existing software routers. However, Packet Shader does not utilize the memory architecture in the GPU system. Basically, GPU has different types of memories such as constant, texture, and global. Since different types of memories show different memory access performance, we propose a unique index architecture for the forwarding table by exploiting the memory architecture of the GPU system. Through a preliminary evaluation, we show that the forwarding table lookup using GPU can outperform the CPU only system.

In this paper, a high throughput routing protocol, using the MAC layer information, for Multi-Rate Ad-hoc Networks is proposed. By choosing the route with the minimum value of the proposed “Route Assessment Index”, the selected route is ensured to have high throughput with link's reliability. Also, link bottleneck could be avoided in the chosen route. Hence, the packet drop rate is also decreased. The correctness of the proposal is proven and the simulation results show that our new metric provides an accurate and efficient method for evaluating and selecting the high throughput route in Multi-Rate Ad-hoc Networks.

We derive a spherical linear interpolation (SLI) with a closed-form phase term. The derived SLI is compared with the geodesic interpolation. Simulation results show that both schemes are efficient and similar when the channels are highly correlated, since their objectives are equivalent in a sense of minimizing the distance between two adjacent codewords.

In this paper, a new low-complexity partial transmit sequence (PTS) scheme is proposed, which generates alternative signal sequences by adding mapping signal sequences of each subblock to each signal subsequence. The proposed scheme considerably reduces the computational complexity without sacrificing BER and PAPR reduction performance, especially for the OFDM system with quadrature amplitude modulation (QAM).
