The International Conference on Information Processing in Sensor Networks (IPSN) brings together researchers from academia, industry, and government to present and discuss recent work in the emerging field of wireless sensor networks. IPSN draws upon many disciplines including signal and image processing, information and coding theory, networking and protocols, distributed algorithms, wireless communications, machine learning, embedded systems design, and databases and information management.

To further foster the collaboration between theory and system researchers, this conference will feature two interleaving tracks:

  • IPSN, focusing on information processing algorithms.

  • SPOTS, focusing on platform tools and design methods for network embedded sensors.

IPSN will also host the following exciting events:

Paper Submission

Follow this link to register and submit a paper to the IPSN track. Note: This link is for the IPSN track only.

Follow this link to register and submit a paper to the SPOTS track. Note: This link is for the SPOTS track only.

Templates for formatting submissions

A paper must be original material that has not been previously published nor is currently under review by another conference or journal. Submitted papers should be no longer than 10 pages in ACM two-column format for conferences (see the template above). Note that the font size for submission should be 9pt. Papers that do not meet the requirements on size and format will not be reviewed. Authors should include their names on their paper submissions and do not need to obscure references to their existing work.

Using the default ACM style may produce papers in A4 (not US Letter) format. The problem happens with pdflatex not with latex. It can be fixed it by following the direction of the link The key changes are as follows.

When compiling a document using pdflatex (under the default installation of teTeX) the paper size (page size) may be set incorrectly if calls to the Vmargin or Vpage packages are used. To correct this you should perform the following modification: In pdftex.cfg ($TEXBASE/texmf/pdftex/config/pdftex.cfg) remove or modify the lines:

page_width 210 true mm
page_height 297 true mm

So that they correspond to your desired default page size. An example entry for letter sized paper would read:

page_width 8.5 true in
page_height 11.0 true in
