Low-density parity-check (LDPC) codes form an important subclass of error correcting coding techniques, and its implementation has been hot spot of domains such as signal process, magnetic recording or next generation communication for years. This paper proposes a configurable FPGA implementation of Partition-and-Shift LDPC decoder based on Min-Sum algorithm. An MPEG algorithm is introduced to reduce...
Internet routing protocols currently in use in the typical protocol of the existing BGP protocol to strengthen the security of the BGP protocol by comparison with research on emerging issues of the AS-Path, IP Fake, DRDoS BGP protocol must be used when such the information you need, but due to malicious attack, or an incorrect setting can prevent the global Internet network operating in an effective...
Router has acted as more and more important role in the large-scale network. In the meantime, the security of the router become more seriously. In this paper, we propose a new algorithm to decide a credential routing path from the start router to the end one based on the trust theory that considers the trustworthy of link, the cost of link and the trustworthy of router as the critical factors so as...
Routing algorithm is the key part of public traffic query system. It is important in GIS applications. This paper investigates a lot of the public traffic routing algorithm, analyzes the bus transit networkpsilas characteristic, and therefore constructs a new model of the least times transfer priority algorithm based on database. The algorithm takes the least times transfer as the first goal, considering...
Secure route selection is always a challenge for distributed networks. The paper takes trust value as one of routing metrics for distributed networks to defense some attacks. The paper provides an algorithm to compute trust value and then gives a routing algorithm based on trust value. Trust value's computation takes remembering factor and credibility as main parameters. The final route is secure...
