摘要:
A fuel-saving path planning navigation system and a fuel-saving path planning method thereof. A plurality of sensors monitors a plurality of roads respectively and periodically report traffic information to a server. The server comprises a storing module and a processing module. The storing module stores the traffic information as history information. The processing module estimates how many vehicles on a road based upon the history information, calculates fuel consumption of each possible planned path including current fuel consumption based on real-time traffic and future fuel consumption based on the historical information, and plans a most fuel-efficient path. Also, the processing module recalculates fuel consumption of remaining path and changes the remaining path while fuel cost of a new path better 10% than the remaining path.

A method of group guiding service in wireless sensor networks and a system using the same are disclosed in this invention. According to this invention, wireless sensor networks may be utilized to track the position of the group leader and provide leader information and guiding services to the group members. The location of every group leader is able to be traced by the sensor network in accordance with a leader device and the technology of wireless communication. In addition, a multifunctional guiding director and the RFID system are also utilized in this invention.

A dynamic taxi-sharing system and a sharing method thereof. A ride-sharing service provider carries at least one passenger from the first current location to the first travel destination through a route in an area and sends registration information to a service server. A plurality of ride-sharing requests is sent to the service server, and each of the ride-sharing requests comprises the second current location and the second travel destination. The service server divides the area into n by n blocks. A ride-matching module of the service server chooses a destination area in which the first travel destination is a center point and divides the destination area into k by k blocks. According to the registration information and the ride-sharing requests, the ride-matching module matches at least one ride-sharing traveler to the ride-sharing service provider to achieve a goal of fuel-saving and pollution-reducing.

A packet transmitting method of wireless network is provided. The packet transmitting method determines whether the packet to be transmitted is a real-time packet or not, and, when the packet is a real-time packet, a re-transmission mechanism of the packet is determined to be ON or OFF according to the transmission status of the wireless network itself.
