Increasing fault tolerance by means of bee colony optimization algorithm to replace destroyed node in Networks-on-Chips

Without doubt, limitation of energy resources has been mentioned as one of the most important problems in wireless sensor networks. Small size , low weight and contingency arrangement which are mentioned as the requirements for the special applications of wireless sensor networks cause sensor nodes rely on small batteries to supply their consumption energy. In addition, efficiency of wireless sensor networks relies on longevity and maintenance of their network coverage. Thus, the entire levels of these networks must be designed with awareness from energy. Routing is one of the most important problems raised in these networks. Numerous efforts have been made to propose informative energy routing techniques in wireless sensor networks. The present research has intended to routing in on-chip network using bee colony optimization algorithm. Fault tolerance is fulfilled in this way that new route is specified in the route specified via collision with the destroyed node in the optimal route.
