In this article we discuss the use of commonly deployed IP multicast protocols in UMTS networks. We analyze three possible UMTS multicast architectures, all employing standard IP multicast protocols. We study the architectures' ability to handle: group management, data-security, authentication and authorization of multicast source/receivers, multicast(More)
Due to the nature that high datarate leads to shorter transmission range, the performance enhancement by high datarate 802.11 WLANs may be degraded when applying high datarate to an 802.11 based multihop ad hoc network. In this paper , we evaluate, through extensive simulations, the performance of multihop ad hoc networks at multiple transmission datarates,(More)
Due to the fact that high datarate has shorter transmission range, the benefit of using high datarate may be degraded for IEEE 802.11 based multihop ad hoc networks. In this paper, we evaluate the performance of multihop ad hoc networks at multirates, in terms of the number of hops between source and destination, throughput, and end-to-end delay. Through(More)
