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, 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.

This paper reviewed brief transition of TV services and new challenge from existing TV service domains. We reviewed different service roles for each TV service domains, as well common direction and goals. Recently, new types of TV service are emerging, for example, IPTV from network providers, more competitive portal TV from content providers and advanced TV terminal from TV manufacturers. Also, we suggest a seamless TV service scenario between TV domain and mobile domain, which demands several service requirements to provide such kind of seamless TV service in current vertical TV environments. From this example, we focused on existing relevant standardization requirements from W3C and ITU-T. As well, further requirements are considered for harmonization of current standards.

We propose a Network Allocation Vector (NAV) based Load Aware Routing (NA-LAR) protocol for Wireless Mesh Networks. NA-LAR is basically based on the Directional AODV (D-AODV)) to reduce the number of route request packet broadcast by using a restricted directional flooding technique. It also considers network conditions with NAV which indicates the busyness of the medium in IEEE 802.11, and it is used to find load balanced routing path. Thus, NA-LAR can find a less loaded route, and it leads to network performance improvement. Simulation results show that NA-LAR compared with D-AODV could increase the total throughput and reduce the end-to-end delay.

Jamming attack by adversaries is the critical threat in Network Centric Warfare that uses tactical wireless networks. Thus research on developing new networking protocols that are resilient to such attacks are of high importance. Geocasting is a prominent routing mechanism in tactical networks to send critical messages such as alarm about chemical attack, guerrilla detection etc, to the nodes within a specific geographical region. To apply geocast protocols in the tactical environment, it should provide assurance that the packet delivery is reliable despite of jamming attacks. In this paper, we propose two jamming resilient geocasting schemes for tactical mobile ad hoc networks. Our first scheme called the “Failure-Based Learning” in which the sender nodes are not aware of the jamming attacks and try to send packets repeatedly. This method is enhanced by another scheme called “Detour by Anchor Point” with information about the jamming attack which sent to the source node, such that it can proactively avoid the jamming region for successful packet delivery. The simulation results show that our proposed schemes significantly outperform single and dual path geocasting protocols under jamming attack and mobile scenarios.

In this paper, an adaptive constellation scheme for two-way relay communication systems with asymmetric channels is proposed. In this scheme, each node transmits codeword generated by the same turbo encoder to a relay node using different signal power and the relay node decodes the received codeword from each node. Then, the relay node re-encodes and combines these two decoded data sequences using new constellation mapping and broadcasts the resulting signal to each node. This new constellation scheme adaptively adjusts the power level for each user's data by considering the channel conditions. It is shown that the proposed scheme has better frame error rate than the fixed constellation case and XOR case.
