In this paper, we propose a design of the implementation for a search and rescue system for mountain climbers and evaluate the performance of the system. Search and rescues of people in emergency situations in mountain areas have been difficult due to lack of information about their location. In the proposed design, several small and commonly-available RF-based sensors, some amount of storage and processing devices are used. Infestations offer geographically intermittent coverage at high speeds. The proposed mountain climber tracking system use the directed diffusion scheme combined with infostation system. We also analyze the performance of the proposed system with NS-2 simulation package. From the performance analysis results, we expect that the proposed system will be very useful to early detect climbers' locations in emergency situations in Korea mountain areas.

This study was aimed to specify health-related push and pull factors in mountain climbing and provide effective management strategy for mountain-based recreational setting through the identification of the reciprocal relationship between the push and pull factors. The results of survey by 440 mountain climbers at Mt. Dobong, Mt. Bukhan, Mt. Kwanak, and Mt. Cheonggye showed that three dimensions were respectively derived from health-related 15 push items and 11 pull items; therapeutic care, mental health, physical fitness in push factors and cultural, socio-economic, and natural environment in pull factors. According to an analysis of influence between push and pull factors, natural environment was reported to be the greatest influencing pull factor on therapeutic care and physical fitness, and socio-economic environment was on mental health.

A mobile ad hoc network (MANET) is a kind of wireless ad hoc network. It is a self-configuring network of mobile nodes connected by wireless links. Infostation is a lower cost and low power system that provides very high bit rate with limited coverage. In this study, we propose search and rescue system that combines MANET of climbers with Infostations. A climber shares location information of climbers with other climbers while climbing, and delivers the information to Infostations. This system is an intermittent network due to the mobility of nodes. From the system, we can track the locations of missing climbers. Ultimately, proposed system achieves low cost and reduces memory requirement using Infestations. We also analyze the performance of the proposed system by simulation. From the performance analysis results, we expect that the proposed system will be very useful to early detect climbers' locations in emergency situations in Korea mountain areas.
