Rate Allocation for Wireless Multimedia Sensor Networks Using Pricing Mechanism

A bandwidth allocation algorithm for wireless multimedia sensor networks is proposed in this paper. On the premise ofInitialallocation algorithm based on distortion and congestion model to provide an efficient system performance, the allocation algorithm based on pricing mechanism we proposed balances the real-time requirement of different users by adjusting the bandwidth price in each network and each slot. Simulation results show that the proposed algorithm balances the bandwidth ratio of different users according to the video complexity, and it can provide a good system performance guaranteeing the fairness among the users.
