In this paper, we propose a routing technique, “recursive Loop-Free Alternates (rLFAs)”, to alleviate packet loss due to transient link failures. The technique consists of a backup path calculation with corresponding re-routing scheme based on the Loop-Free Condition (LFC) as defined in the basic specification for IP Fast Re-Route (IPFRR). Under this routing strategy, nodes calculate backup paths...
Wireless Sensor Networks (WSN) display nonuniform energy usage distribution. This is mainly induced by the sink centric traffic or by non-uniform distribution of sensing activities and manifests as energy holes throughout the WSN. Holes can threaten the availability of the WSN by network partitioning and sensing voids. They are hard to predict, and consequently, proper function of the network requires...
Peer-to-peer (P2P) file-sharing networks are gradually becoming popular. Among them, eMule's KAD, a network deployed to publish and search files for eMule, is a typical example. Despite the popularity of KAD, its routing performance still has much room for improvement. This paper presents a novel approach to improve the routing performance of KAD through social network analysis. We propose a novel...
