Ad hoc networks are a type of mobile network that function without any fixed infrastructure. One of the weaknesses of ad hoc network is that a route used between a source and a destination is to break during communication. To solve this problem, one approach consists of selecting routes whose nodes have the most stable link cost. This paper proposes a method for improving the low power distributed MAC. This method is based on the context awareness of the each nodes energy in clustering. We propose to select a new scheme to optimize energy conserving between the clustering nodes in MANET. And this architecture scheme would use context-aware considering the energy related information such as energy, RF strength, relative distances between each node in mobile ad hoc networks. The proposed networks scheme could get better improve the awareness for data to achieve and performance on their clustering establishment and messages transmission. Also, by using the context aware computing, according to the condition and the rules defined, the sensor nodes could adjust their behaviors correspondingly to improve the network routing.

This paper introduces a network security situation awareness tool using a traffic pattern map which facilitates recognizing a current network status by extracting and analyzing predetermined traffic features and displaying an abnormal or harmful traffic which deteriorates network performance. The traffic pattern-map consists of $26{\times}26$ intersections, on which the occupancy rate of the port having maximum occupancy is displayed as a bar graph. In general, in case of the Internet worm, the source address section on the traffic pattern map is activated. In case of DDoS the destination address section is activated.

In this paper, we proposed the relay node selection scheme using property of node such as velocity, direction in Delay Tolerant Networks. the existing selection scheme is caused the problem increasing the transmission delay and packet loss, if select the relay node for different mobile with destination. To overcome this problem, we proposed the relay node selection scheme using the property of mobile node. the proposed scheme represents and shares the property of mobile node. The proposed algorithm assumed the sketchy position of node from mobile node delivering property of destination. In addition, the propose algorithm recognizes and analyzes the context of mobile node to provide the relay node transferring the data efficiently. The simulation result provides the better result in terms of transmission delay and packet delivery ratio by selecting transmission by relay node according property of node.

The purpose of this study was to evaluate and maximize the value of Dokdo as a marine educational tourism destination. The purpose of this study was to contribute to the identification of Dokdo as a unique territory of Korea rather than a disputed territory by further activating Dokdo tourism. The revitalization of Dokdo tourism was reviewed and analyzed from the viewpoint that it is possible when Dokdo is recognized as a destination for marine educational tourism. As a result of reviewing various research papers, periodicals, and government documents published in Korea and abroad, it is necessary to emphasize on-site education such as patriotism, anti-Japanese consciousness, and historical awareness in order to maximize value as a marine educational destination of Dokdo. Points out that it is possible to differentiate from other tourist destinations. Second, it pointed out that Dokdo preserves and develops to maximize the resource value of various tourism resources it possesses. Third, it pointed out to develop specialized tourism resources that can be linked with Dokdo tourism. Fourth, it pointed out that Dokdo will maximize its development potential as a marine educational tourism destination. Fifth, it is pointed out that there is a need to improve the educational program related to Dokdo. Finally, I pointed out that I would like to develop a variety of marine educational tourism contents and tourism programs linked with Ulleungdo.

As the globalization increased, cultural heritage has been widely used as tourist destination. Traditional temples which have valuable cultural resources are important cultural heritages. It was found that most traditional temples which were used as famous tourist destinations lost their intrinsic religious values because of the intensive tourist uses. Sustainable tourism was introduced as an alternative tourism to the conventional one which could cause the destruction of the intrinsic values. Sustainable tourism represents and encompasses a set of principles balancing between visitor satisfaction, economic revitalization of the area, and the conservation of the heritage resources. The purpose of this study was to evaluate the possibility for the sustainable tourism of cultural heritage (traditional temple) by investigating visitors' satisfaction, revisit intention, and awareness on conservation. In order to perform this purpose, Sin-heung-sa was selected as a study site and 339 visitors participated in the questionnaire survey. The study results are summarized into three important findings. First, it was found that the possibility for the sustainable tourism of Sin-heung-sa was high. Vistors' awareness on conservation is high, but visiting satisfaction was medium-high. Specifically, the awareness for heritage transmission was the highest and the awareness for other conservational dimensions such as need for education, conservation for surrounding area, and respect for environmental capacity were also high. Second, visitors' overall and separate satisfactions were not high. Therefore, it was recommended that management strategies are needed to increase the visitor satisfaction because both conservation and visitor satisfaction are essential elements of successful sustainable tourism. The results revealed that visitors' satisfaction could be enhanced by improving safety of the area, providing diverse travel activities and information, and creating unique atmosphere. Third, the revisit intention was evaluated higher than the overall satisfaction, which showed that the attractiveness and competitiveness of Sin-heung-sa was relatively high. Important determinant attributes for revisit intention were analyzed to be good nature(landscape, valley, the fauna and flora) and network with surrounding tourist destinations.

The Tactical Internet(TI) managed by Infantry Brigades is used for the purpose of sharing information of Command Control and Situation Awareness. When there are more than two destinations to transmit data in the TI system, a multicasting is utilized based on pre-defined multicast groups. However even in the case when a source node needs to send some messages like weathercast and attack alarm etc to only a part of Battalion or Brigades in a specific geographical region (destination region), the current TI multicasting protocol is designed to transmit the messages to the pre-defined group or all of the Battalion/Brigade nodes, resulting in inefficiency in terms of end-to-end delay and overhead. In this paper, we propose more efficient protocol for such cases, named as "Tactical Internet Geocasting (TIG)". The proposed scheme firstly checks whether the destination region belongs to one Battalion region or more than two Battalion regions using location information, and then performs a greedy forwarding from the source node to the destination region, followed by a local flooding inside of the destination region. With performance analysis and simulations using NS-2, TIG is compared to the current TI multicasting protocol (i.e., Simplified MDP) and the LBM (Location-based Multicast). The simulation results show that the proposed TIG is more efficient than both in terms of delay and network overhead.
