An efficient negotiation protocol for real-time multimedia applications over wireless networks

A new negotiation protocol is proposed to reduce network resources waste for real-time multimedia services over wireless networks. Existing negotiation protocols for wireless communications can be classified into two categories: network-oriented negotiation and application-oriented negotiation. Currently, the research on the two categories are separated. This causes inefficient resource utilization, especially for real-time services, which have stringent quality of service (QoS) requirements. In this paper, a new negotiation protocol is presented, which combines application-oriented and network-oriented negotiation to achieve higher resource utilization. We design a protocol architecture and negotiation messages for three scenarios. Simulation results show that our protocol achieves higher bandwidth efficiency and shorter negotiation delay.
