Emergency Mobile Mesh

The Emergency Mobile Mesh (EMM) project is a communication protocol that allows for intercommunication between emergency, security or defence users. EMM can also be seen as a data exchange protocol that allows for shared situational awareness, helping to support mission success. Finally, EMM was validated via a demonstrator that uses both protocols in a typical case of support for emergency operations.

The EMM project can be included in the research area of communication and information systems in critical systems, allowing multi-purpose uses in areas such as civil protection, security and defence.


CRITICAL Software signed a contract with IAPMEI under the Incentive Scheme for Research and Technological Development to develop EMM project. Contract Number: 2012/24652.

The following organizations are part of the consortium:

  • CRITICAL Software (lead promoter);
  • Instituto de Telecomunicações - Universidade de Aveiro (sub-contractor);
  • Exército Português (end user).


The goal of this project is to develop technologies and dual-use tools in the field of shared situational awareness, which can significantly improve the users experience in situations with dynamic environments and independent or non-existent communication infrastructures.

Investment & Timeframe

The EMM was submitted to the QREN, under the notice of contest N.17/SI/2011. The project was approved, with financial incentives for an overall investment of 210.108,78€ between September 1, 2012 and April 30, 2014.
