In this paper, we propose a delay-tolerant secure long-term health care scheme (Health-Post) to monitor patient's sensitive personal health information (PHI), particularly at the rural areas. To minimize the overall health care cost, Health-Post provides network connectivity to rural areas in developing region using conventional transportation vehicles (e.g., cars, buses) as relay nodes. These vehicles...
Geographic message forwarding in vehicular ad hoc networks (VANET) has attracted much attention and become one of the most promising research areas recent years. In this paper, inspired with the intuition that drivers' route are with high regularity, we propose a prediction-based message forwarding strategy named Seer. Seer trains a 2nd-order Markov model based on long-term historic trip GPS data...
Location based routing protocols are often used to deliver packets in VANET for the sake of scalability and lower overhead. Before exchanging information between moving vehicles, the location of destination node should be discovered. However, the existing location service employed in MANET is not very suitable for vehicular ad hoc network. In this paper, a vehicle location service protocol (VLS) is...
