For time-delay, noise and network congestion in the communication among agents, there are random communication link failures among agents. In the paper, we analyze the distributed flocking algorithms under virtual leader-follower model with random communication link failures. Under virtual leader-follower model, flocking algorithm can avoid diverging, but the performance of flocking algorithm with link failure often degrades. We analyze the impact brought by link failures on the flocking algorithm when part agents can’t receive the information of the virtual leader, and simulations are done. Results show that the performance of distributed flocking algorithm depends on the probability of link failure. Smaller is the probability of link failures among multi-agents, better is the performance of flocking algorithms with link failure.

For time-delay, noise and network congestion in the communication among agents, there are often random communication link failures among agents. In this paper, we analyze the pseudo two-hop distributed consensus algorithm with link failures, and research the relation between convergence performance and the probability of link failures. Supposing that the probability of link failures in every link is independent identically distributed, we analyze the convergence performance of the pseudo two-hop distributed consensus algorithm with link failures, and simulation results are provided to verify these analytical results.

Vertically stacked optical banyan (VSOB) networks are attractive for serving as optical switching systems due to the desirable properties (such as the small depth and self-routing capability) of banyan network structures. Although banyan-type networks result in severe blocking and crosstalk, both these problems can be minimized by using sufficient number of banyan planes in the VSOB network structure. The number of banyan planes is minimum for rearrangeably nonblocking and maximum for strictly nonblocking structure. Both results are available for VSOB networks when there exist no internal link-failures. Since the issue of link-failure is unavoidable, we intend to find the minimum number of planes required to make a VSOB network nonblocking when some links are broken or failed in the structure. This paper presents the approximate number of planes required to make a VSOB networks rearrangeably nonblocking allowing link-failures. We also show an interesting behavior of the  blocking  probability of a faulty VSOB networks that the blocking probability may not  always  increase monotonously with  the  increase  of  link-failures; blocking probability  decreases  for  certain range of  link-failures, and then increases again. We believe that such fluctuating behavior of blocking probability with the increase of link failure probability deserves special attention in switch design.  Keywords: Banyan networks; Blocking probability; Switching networks; Vertical stacking; Link-failures. © 2009 JSR Publications.
