Emerging portable software defined radio (SDR) technology has great potential for improving the communication capability of dismounted and Special Forces personnel. This is because of SDR’s ability to quickly acquire operational information in a hostile environment, and to adapt to it based on spectrum needs and available resources. The major challenges lie in the following five aspects of effectiveness of spectrum sensing, network identification, effective network assessment, advanced security mechanisms, and spectrum adaptation. Most of the existing research focuses on enabling technologies like spectrum sensing and adaption, and the remaining areas are not well researched. Further, the current development is still in its early stages and demands further investigation. To support diverse mission requirements and needs, all five aspects should be fully leveraged and equally emphasized. To address this critical need, IAI has been awarded a contract to develop a dynamic Network Sensing, Assessment, and Intrusion Detection (NetSAID) system on portable SDR platforms. This work will enable dismounted and Special Forces personnel to rapidly adapt to hostile environments and acquire relevant operational information. The proposed approach will significantly improve reliable and secure access to battlefield networks, as well as provide enhanced support for situation awareness. Both military and civilian first responders who use SDR technology will benefit from adaptable and re-configurable SDRs. This effort will also fulfill the demand for better security strategies and intrusion detection software for SDR technology.
