Due to their popularity, dense deployments of wireless local area networks (WLANs) are becoming a common feature of many cities around the world. However, with only a limited number of channels available, the problem of increased interference can severely degrade the performance of WLANs if an effective channel assignment scheme is not employed. Previous studies on channel assignment in WLANs almost...
In this paper we study the convergence behaviour of dynamic power control algorithm for ad hoc networks when a number of non-overlapping channels are available. The convergence condition is expressed in terms of an inequality relationship which depends on the link gains, the required QoS and the number of available channels. The results are demonstrated by simulations with different number of nodes...
We study the behaviour of dynamic power control algorithm and derive new sufficient conditions for the dynamic to be convergent. The convergence condition is based on the properties of diagonally dominant matrices and an additional condition required for the real parts of their eigenvalues to be negative. The essential condition for the power dynamic to be stable is expressed in terms of relationships...
