Most metaheuristics contain a randomness component, which is usually based on uniform randomization –i.e., the use of the Uniform probability distribution to make random choices. However, the Multi-start biased Randomization of classical Heuristics with Adaptive local search framework (MIRHA, Gonzalez-Martin et al., 2014a; Juan et al. ,2014a) proposes the use of biased (non-uniform) randomizati...

Multistage Interconnection Networks (MIN) are popular in switching and communication applications. It has been used in telecommunication and parallel computing systems for many years. The new challenge facing optical MIN is crosstalk, which is caused by coupling two signals within a switching element. Crosstalk is not too big an issue in the Electrical Domain, but due to the stringent Bit Error...

we consider a grid network where nodes contain small buffers. a packet that faces a crowded buffer in its route will get extra latency and may be dropped. in this paper, we propose a novel flow control protocol called rfcc for grid networks. rfcc tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

The popularity of the great variety of Internet usage brings about a significant growth of the data traffic in telecommunication network. Data transmission efficiency will be challenged under the premise of current network capacity and data flow control mechanisms. In addition to increasing financial investment to expand the network capacity, improving the existing techniques are more rational ...

Survivability refers to keeping a system partially or fully operational when one or more of its components fail. Survivability in telecommunication networks is crucial, as failure of a network component can potentially bring down the whole communication network, as happened in some real-world cases. Adding redundant network components increases the survivability of a network, but cost of the ne...
