In this work, we study the NP-hard problem of maximizing lightpath reliability in optical mesh networks against simultaneous failures of multiple fiber links. The fiber links belong to shared risk link groups (SRLGs) that have arbitrary failure probabilities. We study three heuristic algorithms and evaluate their performance through simulations.
We investigate optimal resource allocation for delay-limited cooperative communication in time varying wireless networks. Motivated by real-time applications that have stringent delay constraints, we develop dynamic cooperation strategies that make optimal use of network resources to achieve a target outage probability (reliability) for each user subject to average power constraints. Using the technique...
In order to improve communication reliability of power line carrier sensor network, a network topology dynamic discovery algorithm based on improved ant colony algorithm is proposed. The network topology discovery issue is changed into the minimum spanning tree of map by optimization strategy which based on antspsila election roads. Moreover, the idea of depth-first search is combined with to ensure...
