Intelligent optimization algorithms based on biological mechanisms have better performance than traditional ones in solving complex multimodal function optimization problems. Most of those intelligent algorithms, however, have the problems of degeneration and vibration, which will lead to poor global optimization and low convergence speed. Inspired by the features of MHC (Major Histocompatibility...
Multicast is widely applied for multimedia communications in Internet. The effective multicast routing is the key technology to the communications. The Qos of multi-constrained multicast routing problem deserves more attention. The objective function is to minimize the cost and meet multiple constraints to realize high Qos. The solutions' fitness is obtained by the concentration mechanism of immune...
To control wireless network congestion, an adaptive QoS and wireless bandwidth (adaptive-QWB) was designed in this paper. The adaptive-QWB algorithm seeks an active queue management for the optimal target queue according to the dynamic varying rate of current bandwidth. The experiment results show that the varying-time of adaptive wireless bandwidth and the QoS guaranteed in transmission delay with...
This paper studies the traffic hot spots of mesh networks in the context of chip multiprocessors. To mitigate these effects, this paper describes a non-uniform fat-mesh extension to mesh networks, which are popular for chip multiprocessors. The fat-mesh is inspired by the fat-tree and dedicates additional links for connections with heavy traffic (e.g. near the center) with fewer links for lighter...
This paper proposed a pursuit-evasion algorithm based on the Option method from hierarchical reinforcement learning and applied it into multi-robot pursuit-evasion game in 2D-Dynamic environment. The algorithm efficiency is studied by comparing it with Q-learning. We decompose the complex task with option method, and divide the learning process into two parts: High-level learning and Low-level learning,...
OLT can correctly predict the upper edge and down edge of the packet that reached by DBA GRANT by reshaping all packets arriving and buffed in queues in a cycle during ONU idle time. By adjusting the last GRANT to reach the nearest edge of the packet, all USRs are not only eliminated, but also the whole USR size is reduced, the average cycle length and the average GRANT are kept unchanged, the available...
