A new algorithm, IP traceback algorithm based on deterministic linear network coding (DLNC) is proposed. The new algorithm applies the deterministic linear network coding to the probabilistic packet marking algorithm. Theoretical analysis and simulation in NS2 environment show that the new algorithm reduces the amount of packet needed to reconstruct the attack path, improves the computational complexity...
On-line program download of in-vehicle ECU required to be implemented according to diagnostic protocol ISO15765. Now, it's short of convenient and flexible download tool, which is low-cost. For this problem, on-line downloader based on ISO15765 is designed in this paper. Strategy of downloader system is designed, three main function modules are illustrated in detail. Test and application results show...
Session initiation protocol (SIP) has already been accepted as the multimedia control signaling standard in ubiquitous wireless network by IETF and 3GPP etc. However, the handover procedure with SIP suffers from undesirable delay for real-time multimedia applications in WLAN. Moreover, the existing handover management protocols are not sufficient to guarantee handover of VoIP session in WLAN. In this...
The IEEE 802.16e standard proposes the idle mode to conserve power and operation resource. Under this mode, we propose a dynamic date path strategy based on fuzzy logic control algorithm to decrease the cost of location management for the users of different moving patterns. We analyze the performance of the dynamic data path strategy and basic strategy. The result shows that our strategy is cost-efficient.
Group key distribution is faced with two important problems, i.e. reliability and scalability, to support security multicast for large and dynamic groups. With group member increasing, traditional reliable multicast protocol can not deal with them fully. In this paper, we provide gossip-based group key distribution idea for wide-area dissemination. It is a gossip-based loss recovery control mechanism,...
