DETECTION AND MITIGATION OF WORMHOLE ATTACKS IN MANET

C., Tirumalesh (2009)

In a Mobile ad-hoc network (MANET), because of its dynamic nature, all the nodes must cooperate with each other and participate in routing. Most existing routing protocols for Ad-hoc networks rely on this cooperation. ...
FPGA IMPLEMENTATION OF GSM BASEBAND PROCESSING FOR RECONFIGURABLE SOFTWARE DEFINED RADIO

Gaddam, Srinivas (2009)

Software defined radio is a feasible solution for reconfigurable radios, which can perform different functions at different times on the same hardware. The partial reconfiguration is the key feature of software defined ...
PRIVACY PRESERVING SEQUENTIAL PATTERN MINING OVER DISTRIBUTED PROGRESSIVE DATABASES

Anita, Mhatre Amruta Ajit (2009)

Frequent Sequential Pattern Mining, commonly known as Sequential Pattern Mining is a data mining technique used to find interesting patterns in a large collection of data items. A common example of sequential pattern mining ...
EXPLICIT LOSS NOTIFICATION SCHEMES FOR IMPROVING TCP PERFORMANCE OVER WIRELESS NETWORKS

Digambar, Ingawale Abhijeet (2009)

TCP is designed to perform well in traditional wired networks with the assumptions that packet losses are mainly due to network congestion and random bit error rate (BER) is negligible. However, wireless networks suffer ...
SECURE GROUP- REKEYING USING BALANCED BINARY TREE IN DISTRIBUTED ENVIRONMENT

Senko, Ranjit (2009)

Secure group communication is important for building distributed applications that work in dynamic network environments and communicate over insecure networks such as the global Internet. They can be used to building fault ...
AN INTRUSION DETECTION SYSTEM FOR WIRELESS SENSOR NETWORKS

Lokhande, Sandip (2009)

In recent years, wireless sensor networks have many potential applications for both civil and military tasks. However, sensor networks are susceptible to many types of attacks because they are deployed in open and unprotected ...
A TECHNIQUE FOR DETECTING PARAPHRASES USING HYBRID SIMILARITY MEASURES

Deepak, T. Sai (2009)
