A Scalable Multimedia Multicast Protocol for Emergency Systems

Emergency system and public safety have been of major concern to authorities of all countries in the world for the last decade. It is usually the case that multi- disciplinary rescuers may need to join hands in achieving a common goal; which implies a large number of people to be coordinated. However, the deployment of a multi-disciplinary emergency system and/or the deployment of a public safety system might involve a large number of nodes in ad hoc networks. On one side, scalability of ad hoc networks has always been a challenge mainly because of limited bandwidth and limited resources of the participating nodes. While on the other side, ensuring public safety and the solicitation of quick emergency responses are always desirable but remain challenging. This paper presents a scalable multimedia multicast protocol for emergency system (SCAMMES), based on the affinity of nodes´ movement in a group and the localisation of emergency operations, to distribute multimedia efficiently in Large Ad hoc Networks for Emergency System (LANES).
