Based on analysis and simulations, it is found that extremely high inertia forces will be generated in stamping machine when stroke speed falls in range for ultra high speed stamping machine if a regular crank-slider mechanism is used. This paper presents a design method to lower the inertia forces by using balancing structure. The effectiveness of the proposed structure is validated through simulations...
Both TDMA and CSMA are effective media access protocols, which can also be important elements of more advanced protocols. In this paper, we investigate TDMA and slotted CSMA protocols in a cognitive radio network, where primary users have higher priority than secondary users and secondary users need to monitor the channel to avoid interference to the primary users. It is thus proposed that TDMA is...
Slotted Aloha and carrier sensing multiple access (CSMA) are effective random access protocols, which can also be important elements of more advanced media access protocols. In this paper, we investigate slotted Aloha and CSMA protocols in a cognitive radio network, where primary users have higher priority than secondary users and secondary users need to monitor the channel to avoid interference to...
Convergecast is a communication structure for wireless sensor networks (WSN) in which data flow from multiple nodes into one node. We use a two-tier slotted Aloha model to analyze the throughput and average packet delay of a convergecast mode based on slotted Aloha. In our model each node has a buffer and we use equilibrium point analysis (EPA) approach to study the model. Rayleigh fading is assumed...
