| Abstract;This paper proposes and evaluates a wireless multi-access protocol, Direct and Relay Communication Protocol(DRCP). The first feature of the protocol is that if terminals can communicate directly, packet relay through the base station is omitted. Only if they can not do due to energy limitation or wave propagation restriction, DRCP relays the packet. This strategy enhances throughput and delay. The second feature is that if a packet is sent to a destination out of the current cell, DRCP dose not relay it to the current cell. In the sending cell, DRCP omits the downlink channel through which the base station relay the packet. In the receiving cell, the protocol omits the downlink channel so that the base station transmits the relayed packet in the "uplink" channel. Evaluation by simulation shows DRCP dominates DQRUMA in some criteria. (author abst.) |
