The admission control component of SQUIRREL, called: Scalable and Accurate Admission control (SAICAC), has two variants: SAICAC-Power and SAICAC-CS. SAICAC-Power estimates channel bandwidth availability through high power transmissions and SAICAC-CS through passive monitoring of the channel. Contrary to the existing intra-flow contention-based protocols, SQUIRREL can ensure all the properties of a self-organizing system and can achieve the best results in terms of of message overhead, delay, and scalability.Ad-hoc networkSelf-organizationIntra-flow contentionAdmission controlScalabilityBook ChapterSpringer-Verlag Berlin Heidelberg10.1007/978-3-540-92157-8_24978-3-540-92157-8
