Abstract—The media access control(MAC) protocol plays an important role in UWB-based wireless multimedia sensor networks (WMSNs). The problems of long acquisition time, large overhead and high collision probability have been addressed most when designing such MAC protocols. To reduce long acquisition time and large overhead, and to support more concurrent transmissions, we proposed a UWB-based MAC protocol for wireless multimedia networks named as UWB-based Receiver initiated MAC protocol with Packet aggregation and Selective retransmission (URMPS). The receiver initiated request, packet aggregation and selective retransmission are used to reduce synchronization acquisition time and overhead. The combination of mutually exclusive area and time-hopping(TH) code is to mitigate the interference caused by concurrent transmissions of multiple nodes. The simulation results run over NS-2 show that URMPS protocol performs better in terms of network throughput and delay compared to S-MAC. By incorporating all of above technologies into URMPS, the objective of improving the network throughput and reducing the network delay is achieved. Meanwhile, it can be used in the networks with moderate data traffic.
