In this paper, we use the self-organizing paradigms presented in [1] to design a new QoS-routing intra-flow contention-based protocol for wireless ad-hoc networks, called SQUIRREL. 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.
