- IDAMN: An Intrusion Detection Architecture for Mobile Networks
- This paper presents IDAMN, a distributed system whose main functionality is to track and detect mobile intruders in real-time. IDAMN includes two algorithms which model the behaviour of users in terms of both telephony activity and migration pattern. The main novelty of their architecture is its ability to perform intrusion...

- Internet Security Architecture
- Fear of security breaches has been a major reason for the business world's reluctance to embrace the Internet as a viable means of communication. A widely adopted solution consists of physically separating private networks from the rest of Internet using firewalls. This paper discusses the current cryptographic security measures available...

- Actively Monitoring Peers in KAD
- In recent years, a large number of DHTs have been proposed. However, very few of them have been deployed in real-life large scale systems. An exception is KAD, a DHT based on Kademlia that is part of the widely used eMule peer-to-peer system, which has more than 1.5 million simultaneous...

- Link-Layer Fragmentation and Retransmission Impact on TCP Performance in 802.11-Based Networks
- The objective of this paper is to examine the behavior of TCP in 802.11-based networks. The focus of this work is mainly on the effect of the fragmentation and frames retransmission handled at the MAC layer on the TCP end-to-end performance. The packet loss rate and the end-to-end delay of...

- LAS Scheduling to Avoid Bandwidth Hogging in Heterogeneous TCP Networks
- This paper proposes using least attained service LAS scheduling in network routers to prevent some connections against utilizing all or a large fraction of network bandwidth. This phenomenon, which is also known as bandwidth hogging, occurs in heterogeneous networks such as networks with connections that have varying propagation delays, networks...

- Channel Modeling and Associated Inter-Carrier Interference Equalization for OFDM Systems With High Doppler Spread
- This paper addresses the problem of OFDM transmission over a time-varying, frequency-selective channel with high Doppler spread.. This paper analyzes the CP-OFDM transmission mechanism, and the impairments due to the channel variations, using a decomposition of these variations over a base of sinusoid functions sampling the Doppler spectrum at subcarrier...
