The sensor nodes on the sensor network transmit the reply for the queries of ADV(Advertisement) message from sink node, and the sink node presents the received information to users. To find the relevant sensor nodes, routing algorithms disseminates ADV messages to the whole network. Thus not only the relevant sensor nodes but also the irrelevant ones consume considerable amount of energy. To alleviate such kind of energy consumption, this thesis proposes a new routing algorithm and coins it Directed Messaging. It propagates ADV message only to the limited direction and changes the direction until the requested sensor node is found. In this way, Directed Messaging reduces unnecessary energy consumption and enhance the efficiency of the networks. Performance of the Directed Messaging algorithm is evaluated through simulation and compared with Directed Diffusion algorithm. Simulation results show that it has better performance than Directed Diffusion.

The femtocell is a miniaturized Base Station (BS) with low-cost and low-power using general broadband access network as backhaul. It is expected not only to improve indoor coverage but also to reduce a service charge. However, in IEEE 802,16e femtocells, when the Mobile Station (MS) scans neighbor BSs for handover, it takes a long time due to too many number of femto BSs. Also the size of the neighbor advertisement message that will be periodically sent by a serving BS is increased as the number of target femto BSs for scanning increases. In this paper, we proposed an efficient femtocell scanning scheme, using a triangulation mechanism and a femto BS monitoring scheme to reduce the number of scanning operations and the size of the neighbor advertisement messages. The proposed scheme can avoid wasting air resources and reduce scanning overheads by minimal scanning operation. The simulation results showed that the proposed scheme could improve scanning performance and avoid wasting air resources, compared with the conventional scheme of the IEEE 802.16e system.

This study set out to examine message orientation in advertising expression through the content analysis of apartment sales advertisements in Busan. For this purpose, the study analyzed newspaper ads about apartment sales in the Busan area in terms of advertising appeal methods and message types. Advertising appeal methods(rational and emotional appeal) and message orientation(environmental, emotional, investment, and functional orientation) were categorized according to brands(nationwide and local brands). The findings show that most of apartment sales ads in Busan used a rational appeal method. While nationwide brands used rational and emotional appeal in similar percentage, local brands used a lot of rational appeal. Of the types of advertising message orientation, investment and emotional orientation recorded the highest percentage. Messages of investment orientation to show economic profit or premium were used most, being followed by messages of emotional orientation to show pride and happiness. These findings were interpreted to display differences in strategies for advertising expressions among brands. The findings are expected to offer useful practical implications for message strategies for apartment sales ads.

For the safety messages in IEEE 802.11p/WAVE vehicles network environment, strict periodic beacon broadcasting requires status advertisement to assist the driver for safety. In crowded networks where beacon message are broadcasted at a high number of frequencies by many vehicles, which used for beacon sending, will be congested by the wireless medium due to the contention-window based IEEE 802.11p MAC. To resolve the congestion, we consider a MAC scheme based on slotted p-persistent CSMA as a simple non-cooperative Bayesian game which involves payoffs reflecting the attempt probability. Then, we derive Bayesian Nash Equilibrium (BNE) in a closed form. Using the BNE, we propose new congestion control algorithm to improve the performance of the beacon rate under saturation condition in IEEE 802.11p/WAVE vehicular networks. This algorithm explicitly computes packet delivery probability as a function of contention window (CW) size and number of vehicles. The proposed algorithm is validated against numerical simulation results to demonstrate its stability.

Because of a security problem and not enough IPv4 address space, the home network has been made up of private network, and it has been separated from Internet. This fact prevents people in Internet from controlling and monitoring home appliances. So, this paper designs and Implements the UPnP Proxy System which offers functions for users to control and monitor home appliances. When users are in the outside of the home network, they do not know which devices were connected in the home network because the advertisement messages of UPnP devices would not be delivered to the outside of the home network. Also, users cannot access devices directly, and their control messages are not delivered into the home network. So, this paper designs and implements the UPnP Proxy System to solve these problems. The merit of the system is that users can control and monitor home appliances in realtime using presentation web documents with the HTTP push technology.

In this paper, we investigated and analyzed influence of tobacco countermarketing advertisements on university students' attitudes about smoking. For the investigation and analysis, we made up a questionnaire twice before and after watching antitobacco advertisements using the same questionnaire. We analyzed message framing, message theme category, and main effects and interaction effects between smoking experiences in attitudes on smoking before(pre-watching attitudes on smoking) and after(post-watching attitudes on smoking) watching antitobacco advertisements by the questionnaire results. In the analysis results using ANOVA test by diverse factors, we verified that efficacy of advertisement messages in positive group of pre-watching attitudes on smoking are better than in negative group. We also verified that interaction effects between message framing and message theme category about changes of post-watching attitudes on smoking are more efficient for changes of smoking attitudes when message theme is negative message rather than positive message.

The main focus of this study is to understand realities of postmodern consumer culture by deconstructing fashion advertisements, Calvin Klein's ck One and cK be. The metaphysics of critical theory, visual and textual analysis are used to deconstructing the ads applying one of the postmodern cultural critics, Baudrillard' s notion of hyperreality. Through deconstructing the ads five postmodern characteristics representing hyperreality were found. First, there is no message regarding functional characteristics of the product offered in the ad, which is far from the modernist's utilitarian Point of view. Hyperreality in Postmodern consumer culture is consumption centered and focuses on the product's symbolic meanings. Second, especially for cK be, the ad uses atypicai, irrelevant models and images, which are introduced as a concept of ‘real people’ rather than the ideal person or body type. Third, there are transformations of the meanings from cK one to cK be such as the notions of globalization and gender which clearly represent ongoing reality in the Postmodern culture. Fourth, there are hidden meaning of hedonism and relativism, which are prevalent in postmodern ideology. Finally, models' bodies are used to convey messages as well as form the ground and figure in the ad that is a significant characteristic of postmodern consumer culture. In conclusion, the study of Calvin Klein's fashion ads supports the notion that advertising mirrors reality in postmodern consumer culture, which is hyperreality.

It is supposed that the future fashion could be made by the scientist instead of fashion designer. Because it is so intellectual and avantguard. In addition to this the practical value and a certain identity is needed in this future fashion. Especially, the intention of no acceptance of categorization could be explained through the fashion clud of young people and the extremeness in the street. Paul Hedmus has insited that Tokyo club is closely related the fashion styles depended on the western historical street fashions. Fashion is mixeded contrasted, modified, resembled, reversed and finally it includes the new neaning. Instead of distinguishable logo there are lots of messages in the fashion. There are a few thousand of young people who wear silver max metal shoes. And they craze the neon picture and advertisement implies meaning the drug. It could be applied to the people of 90's. The difference between sex from the stone age is induced basically from the fashion and the part of discussion of sex. In this study we research the images of future fashion showed in SF Movie, Star Wars, Episode, The 5th Elements, Nirvana. Those were geometric and natural, technological expansion of space, corset fashion acessoruy image and geometric expression and these characteristics implied in modern fashion trend and future fashion images. Because it is supposed to the future image of current fashion. The millenium fashion is more realistic, practical, and natural instinct realization of ideal. but it is not the unrealistic, the vague of the regendary image.

Network clustering has been proposed to provide that sensor nodes minimize energy and maximize a network lifetime by configuring clusters, Although dynamic clustering brings extra overhead like as head changing, head advertisement, it may diminish the gain in energy consumption to report attribute tasks by using cluster heads. Therefore, this paper proposes a new routing algorithm which configures cluster to reduce the number of messages when establishing paths and reports to the sink by way of cluster heads when responding sens ing tasks. All sensor nodes only broadcast bitmap once and maintain a bitmap table expressed by bits, allowing them to reduce node energy and to prolong the network lifetime. After broadcasting, each node only updates the bitmap without propagation when the adjacent nodes broad cast same query messages, This mechanism makes nodes to have abundant paths. By modifying the query which requests sensing tasks, the size of cluster is designed dynamically, We try to divide cluster by considering the number of nodes. Then, all nodes in a certain cluster must report to the sub- sink node, The proposed routing protocol finds easily an appropriate path to report tasks and reduces the number of required messages for the routing establishment, which sensor nodes minimize energy and maximize a network lifetime.
