A more efficient mobile device can be achieved via an optimization process based on display screen dormancy. Application data transmissions can be throttled based on a screen-on or screen-off status of a mobile device. Furthermore, an application management platform can be used to prioritize application data transmissions based on data associated with each application's packet transmissions.

Facilitation of mobile device resource optimization

Detection of user accounts associated with spammer attacks may be performed by constructing a social graph of email users. Biggest connected components (BCC) of the social graph may be used to identify legitimate user accounts, as the majority of the users in the biggest connected components are legitimate users. BCC users may be used to identify more legitimate users. Using degree-based detection techniques and PageRank based detection techniques, the hijacked user accounts and spammer user accounts may be identified. The users' email sending and receiving behaviors may also be examined, and the subgraph structure may be used to detect stealthy attackers. From the social graph analysis, legitimate user accounts, malicious user accounts, and compromised user accounts can be identified.
