CDMA Uplink Power Control as a Noncooperative Game

CDMA Uplink Power Control as a Non ooperative Game 1

Power Control through Noncooperative Game Theory on Wireless Sensor Network

In the sensor network, it is very difficult to use sufficient energy due to limited energy at the sensor nodes. In the distributed sensor network nodes are transmitting signals having extra energy loss. The work presented here suggests that game theory could provide solution of power control problem in CDMA based distributed sensor network. Thus, basic concepts of game theory and distributed se...

Uplink Power Control in QoS-aware Multi-Service CDMA Wireless Networks

In this paper the problem of QoS-driven power control in the uplink of CDMA wireless networks supporting multiple services is considered. Due to the need for supporting simultaneously various services with diverse QoS requirements, each user is associated with a nested utility function which appropriately represents his degree of satisfaction in relation to the expected tradeoff between his QoS...

A Joint Modulation, Rate, and Power Control Game-Theoretic Approach for Uplink CDMA Communications

This work proposes a non-cooperative joint modulation, rate, and power control game-theoretic approach for the uplink of a single cell CDMA system. A generalized approach towards adaptive modulation is introduced, by fitting different efficiency functions of several modulations by means of the Gompertz sigmoid functions. The existence of a Nash equilibrium as well as the best response strategie...

Utility-Based Uplink Power Control in CDMA Wireless Networks with Real-Time Services

In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks, emphasizing on the support of realtime services’ QoS prerequisites. The corresponding problem is formulated as a non-cooperative game where users aim selfishly at maximizing their utilitybased performance under the imposed physical limitations. A user’s utility reflects its degree of sati...
