Using Merkle Tree to Mitigate Cooperative Black-hole Attack in Wireless Mesh Networks

Author 1: Shree Om Author 2: Mohammad Talib

Security is always a major concern and a topic of hot discussion to users of Wireless Mesh Networks (WMNs). The open architecture of WMNs makes it very easy for malicious attackers to exploit the loopholes in the routing protocol. Cooperative Black-hole attack is a type of denial-of-service attack that sabotages… Read full abstract & cite →

Generating Performance Analysis of GPU compared to Single-core and Multi-core CPU for Natural Language Applications

Author 1: Shubham Gupta Author 2: M.Rajasekhara Babu

In Natural Language Processing (NLP) applications, the main time-consuming process is string matching due to the large size of lexicon. In string matching processes, data dependence is minimal and hence it is ideal for parallelization. A dedicated system with memory interleaving and parallel processing techniques for string matching can reduce… Read full abstract & cite →
