Handoff is one of the most important factors that may degrade the performance of TCP connections in wireless data networks. In this paper, we present a lossless and duplication free handoff scheme called LPM (Last Packet Marking) for improving Cellular IP semisoft handoff. LPM signals the safe handoff cue by sending a specially marked packet to mobile(More)
In this paper, we note that the signature-based intrusion detection system (S-IDS) can cause the low accuracy against mutants of intrusion packets. This is because the S-IDS commonly detects network intrusion in data flows by identifying the existence of the predefined intrusion signatures, which is called static intrusion signature configuration (SISC).
