Abstract
Remote Instrumentation Services (RIS) are an important component in PPDR applications, where heterogeneous devices can be present, ranging from measurement instrumentation and environmental sensors to telemedicine equipment. The presence of high disruption and absence of communication infrastructure might represent satellite network the only access possibility to remote areas. This paper focuses on examining the security and networking issues in satellite p2p, remote instrumentation services, and the related PPDR applications; also it highlights the security issues which rise due to high disruption, disconnectivity, and deployment of heterogeneous.
