The Routing Protocols and Node Mobility Models of Vehicular Ad Hoc Networks

Aiming at the problems that the safety information is easy to collide frequently,and the time delay becomes larger when the vehicle density is high in Vehicle Ad Hoc Network(VANET),an On-Demand Power Control Algorithm(ODPCA) based on VANET is proposed.

Real-time Transmission Performance Evaluation of Video in VANET

An On-Board Unit(OBU) is designed and implemented on embedded platform responding to the application scenarios and functional requirements of Vehicle Ad Hoe Network(VANET).

Connectedness assurance of self-organizing network evolution;

Based on the willingness factor which considers the sole mobility and relative mobility of nodes,a stable cluster protocol(SCP),which includes a stable clustering algorithm and a cluster maintenance scheme,is presented for highly dynamic mobile self-organizing networks.

A safety system of optical fiber sensor of methane is described by using WDM(Wavelength Division Multiplexing) technology,DMF(digital match filter) for the process of weak signals which measurement accuracy of wavelength can be highly enhanced and self-organizing network which data can be processed on-line.

Designing of ad hoc network based on TD-SCDMA;

Optimized Broadcast Algorithm in Wireless Ad hoc Network;

The paper introduces the features of GPRS and ad hoc networks.
