A distributed dynamic channel and packet assignment for wireless multimedia traffic

This paper proposes a dynamic channel and packet assignment (DCPA) scheme to serve efficiently circuit-switching (e.g., voice traffic) and packet-switching (e.g., Internet traffic) communications in wireless cellular networks. The DCPA, as a distributed-controlled scheme, assigns channels or packet-slots to handoff and new calls based on their traffic type and channel status of cells. Simulation results, based on a circuit-switching and packet-switching traffic model, show that the DPCA scheme provides better QoS than a dynamic channel allocation scheme designed for circuit-switching communications only
