Abstract : The implementation of a multicast protocol on the packet radio network simulator has been initiated in an attempt to investigate the performance/complexity/efficiency trade off of multiple address protocols in narrowband packet radio networks. A multicast data packet has an address list of up to 8 destinations together with a list of selected relay units. The list of destinations with an amended list of relay units will be included in the data packet transmitted by each identified relay unit. All the results produced are a product of the RSRE Packet Radio Network computer simulation (Reference 1) that had been adapted from a single destination packet, with node by node acknowledgement only, to a multiple destination packet with destination to source acknowledgement. The packets are transmitted with the aim of a fast, reliable, efficient delivery together with a slow but efficient acknowledgement of that delivery. The results obtained, displayed an overall improvement in data throughput with a general reduction in the number of transmissions required to obtain the increased packet delivery. With the limited information throughput existing with the narrow band packet radio protocol any improvement in throughput is considered significant.
