WSN17-5: A Novel Admission Control for Asynchronous Active Link Protected Ad Hoc Networks

In this paper we introduce a novel admission control scheme adapted to asynchronous power control for ad hoc networks. An admission control algorithm helps a new link to decide whether it can achieve its required QoS while the network is stable. Most admission control algorithms are categorized either as time-out or SIR-saturation based algorithms. Both of these algorithms are based on QoS convergence of the new link and require some design parameters for each network configuration. Sometimes if an originally admissible link has a low SIR convergence it will be considered as an inadmissible one and forced to drop out. The proposed algorithm in this paper is designed based on the local measurements of the new link in an asynchronous power control with active link protection ad hoc network. In a network of N links, it can determine definite admissibility of the new link in N power update iterations. This algorithm is much faster than time-out and SIR-saturation based schemes and also does not need any design parameters to be updated. Although this algorithm is adapted to a specific power control algorithm, it can be extended to more general cases.
