• Routing and Information Dissemination
• Resource Management and Awareness
• Peer-to-Peer Systems
• Mobile, Ad-Hoc, and Sensor Networks
• Robustness, Self-Stabilization, and Security
• Synergy of Parallelism in Algorithms, Programming and Architecture

Submission details:

Please indicate in the title of your manuscript whether this is a regular paper or a brief announcement. All regular rejected papers automatically will be considered for brief announcements. Titles of regular papers which should not be considered for this option should mention "full paper only" after the title. Visit this link for submission details.

Regular papers:

A regular paper submission must report on original research that has not been previously or concurrently published. Submitted manuscripts may not exceed ten (10) single-spaced double-column pages. The title page and bibliography are not counted toward the ten pages.  All necessary details to substantiate the claims of the paper should be included in a clearly marked appendix. If desired, the authors can simply attach a copy of the full paper as an appendix.  Regular papers will be allotted 10 pages plus bibliography in the proceedings.

Brief announcements:

Examples of good brief announcements include: work in progress, announcement of tools/libraries, challenge problems posted to the community, corrections to earlier results. Brief announcements may also include smaller results of interest. Submitted manuscripts may not exceed two (2) single-spaced double-column pages for brief announcements. The title page is not counted toward the two pages.

Double-Blind Policy:

Submissions to SPAA 2021 will be double-blind.  Additional details are available at this link.


The program committee will select a set of best and outstanding papers, which will be presented in a special session of the conference.

Safe ToC:

SPAA is proud to be affiliated with the SafeToC initiative.
