In this paper, we propose effective trusted communication (ETC) using two-mode authentication. ETC combines routing protocol and authentication protocol together to provide trusted communication especially in disaster situations. During disasters, a communication system plays an important role in rescuing victims. Due to infrastructure failure, mobile(More)
NS-2 is the most famous simulator among other network simulators. Most of researchers use NS-2 to evaluate their new protocols/architectures. Although NS-2 has much resource and many available tools to generate different characteristics and network scenarios, source codes created on NS-2 is not able to be reused for real implementation. The releasing of(More)
IEEE 802.11p is an approved amendment to the IEEE 802.11 standard and adds enhancements to 802.11 to be suitable for vehicular networks. Several researchers have evaluated the 802.11p in term of transmission range and propagation loss model. In this paper, we study a performance of a complex reliable broadcasting protocol on IEEE 802.11p in real public(More)
Mobile phone is now becoming a necessary gadget in our daily life. Mobile applications have been proposed to advance the function of mobile phone. Location service application is a kind of mobile application that provides location information such as current location of the mobile phone. GPS is the popular technology for location service on mobile phone(More)
In the future, VANET and IEEE 802.11p will play important role in ITS with many applications that improve the quality of traffic. Road environment is one of factors that influences the performance of the wireless communication. Especially for blind corner, the buildings which obstruct the signal may be a big challenge for the data transmission of safety(More)
Boat is one of the most popular vehicles for local people and tourists to travel in Bangkok, Thailand, since there is no traffic jam. Without accurate arrival time, however, boat becomes an inconvenient transportation since the waiting time can be varied from 10 minutes to an hour. In this paper, we propose a novel boat arrival time prediction system by(More)
Implementing Crowdsourcing in arrival time prediction system for public transportation lets people share their pieces of information that they have, such as the transport location or situation, and combine the information together to get the complete picture of the interesting public transportation. However, the system that requires human to input the(More)
An asymmetric link problem is a considerable effect in vehicular network, but usually overlooked by many researchers. Most of researches concerning this problem are extensions on unicasting routing protocols which have a primary route of data transmission. However, reliable broadcasting protocols such as Density-Aware Reliable Broadcasting protocol (DECA)(More)
