چکیده
Recent research and development in the area of next generation train backbones have created an incentive towards the replacement of legacy interconnecting data communication architectures with newer and more innovative backbones. The onboard Ethernet technology has been applied in the train onboard detection sensor network gradually. Network delay is an important factor of detection sensor network quality. This paper analyzes the affection to the network delay of different network topology structure. In addition, the communication network model of onboard detection sensor network based on Ethernet has been constructed by the OPNET Network Modeler. According to the simulation data to analyze the network delay, link load and end-to-end throughput of bus network topology and ring network topology. This will provide technology reference for the onboard detection sensor network and train communication network topology structure optimization.

Unauthenticated event detection in wireless sensor networks using sensors co-coverage
Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...
