Improve the performance to implement region based statistical traffic pattern discovery system for MANET

Many privacy improving techniques have been proposed based on packet encryption to protect the communication privacy of mobile ad hoc networks (MANETs). However, we show that MANETs are still vulnerable under passive statistical traffic analysis attacks. To demonstrate how to discover the communication patterns without decrypting the captured packets, we present Region based statistical traffic pattern discovery system for MANETs. Region based statistical traffic pattern discovery system for MANETs works passively to perform traffic analysis based on statistical characteristics of raw traffic. Region based statistical traffic pattern discovery system for MANETs are capable of discovering the sources, the destinations, and the end-to-end communication relations. Region based statistical traffic pattern discovery system for MANETs perform the traffic analysis as divide the entire network into multiple regions geographically. Empirical studies demonstrate that Region based statistical traffic pattern discovery system for MANETs achieves good accuracy in disclosing the hidden traffic patterns.
