We consider broadcasting in radio networks that are subject to permanent node failures of unknown location. Nodes are spread in a region in some regular way. We consider two cases: nodes are either situated at integer points of a line or they are situated in the plane, at grid points of a square or

β¦ Synopsis
Much research has been done on sorting networks but there are very few results concerning their robustness. Our starting point is the balanced sorting network introduced by Dowd et al. and its single-block robust design of Rudolph obtained at the cost of some redundancy and two permuters external to the network. In this article we introduce a new implementation which is more robust than Rudolph's network and needs no redundancy or external permuters. We also consider a class of single-stage designs with redundancy and compare the characteristics of networks discussed.

Broadcasting is the task of transmitting a message originated at one processor of a communication network to all other processors in the network. A minimal k-fault-tolerant broadcast network is a communication network on n vertices in which any processor can broadcast in spite of up to k line failur
A network G \* is called random-fault-tolerant (RFT) network for a network G if G \* contains a fault-free isomorphic copy of G with high probability even if each processor fails independently with constant probability. This paper proposes a general method to construct an RFT network G \* for any ne
Wide attention was recently given to the problem of fault-tolerance in neural networks; while most authors dealt with aspects related to specific VLSI implementations, attention was also given to the intrinsic capacity of survival to faults characterizing the neural modes. The present paper tackles
