introduction
Introduction
  • Pricing for communication networks
  • Applied to both wired and wireless networks:
    • Congestion control
    • Call Admission Control (CAC)
    • Quality of Service (QoS)
  • Wireless network specific issues?

issues
Issues
  • Spectrum allocation for wireless communication
  • Power control for mobile hosts in CDMA data networks
    • Interference
    • Battery life
  • Incentives to collaborate in MANET

spectrum management
Spectrum Management
  • Players –regulators, operators, manufacturers, and end users
  • Cost –negotiations, administration of the frequency table, surveillance, compatibility, and so on
  • Generally the regulators set the rules and prices

methods
Methods
  • Auction –operators bidding for a license
  • Lottery –qualified operators with little technical differences
  • Sharing –new technologies
  • User fee –pay per use

Pricing-base Power Control
  • Utility– QoS (Signal-to-Interference ratio)

NPG
  • Non-cooperative Power Control Game
  • Nash Equilibrium– a power vector p = (p1, p2, ··· , pN) such that for every j in N, uj(p) >= uj(p’) for all p’ in P.

NPGP
  • NPG with pricing –Pareto Improvement

extensions
Extensions
  • Multi-cell–interference from mobile hosts in adjacent cells taken into consideration as well
  • Base Station–a normalization of the received power at base station to improve the system performance

incentives or disincentives
Incentives or Disincentives
  • Disincentive approach– to detect and isolate the selfish nodes to make the misbehavior unattractive
  • Incentive approach– to promote or reward cooperations using pricing mechanism

ECS 289L Project Report

bandwidth sharing
Bandwidth Sharing
  • Problem definition:
  • Unique solution– iterative algorithm to maximize the sum of users’ utility

ECS 289L Project Report

power constraint
Power Constraint
  • To relay, or not to relay?
  • Mobile hosts’ battery life as a constraint
  • Normalized Acceptance Rate (NAR) - the number of successful relay requests generated to the number of relay requests made by the node.
  • Tradeoff between the NAR and lifetime
  • Optimal NAR–a node cannot improve its NAR without decreasing some other node’s NAR

ECS 289L Project Report

bw and power constrains
BW and Power Constrains
  • Credit Scheme
  • Relay fee is calculated from both BW and power consumption
  • Users’ prices and credit balances stabilize for a static ad hoc network
  • Mobility through the center of the network can increase an individual user’s as well as increase the overall throughput

conclusion
Conclusion
  • Spectrum allocation for wireless communication
  • Power control in CDMA data networks
  • Incentives to collaborate in MANET
  • Relations between the various pricing-based approaches
