Dynamic allocation of power, rate and channel access is a critical task in wireless networks. Capitalizing on convex optimization and stochastic approximation tools, this paper develops a stochastic resource allocation algorithm that minimizes average transmit power under individual average rate constraints. Focus is placed on networks where users transmit orthogonally over a set of parallel channels...
A game-theoretic model is proposed to study the cross-layer problem of joint power and rate control with quality of service (QoS) constraints in multiple-access networks. In the proposed game, each user seeks to choose its transmit power and rate in a distributed manner in order to maximize its own utility while satisfying its QoS requirements. The user's QoS constraints are specified in terms of...
Sometimes the backbone network of Internet experiences congestion because traffic is not distributed rationally. This fact may lead network resources utilized inefficiently. The main idea for load balancing is to alter the route for some traffic. But current approaches with this idea often get such a long route that decrease the quality of service. This paper presents a new flow routing adjustment...
