英文摘要
Nowadays, some MAC standards such as 802.11a, 802.11b, and 802.11g can operate with multiple data rates for QoS-constrained multimedia applications to utilize the limited resources of mobile ad hoc networks (MANETs) more efficiently. In this paper, a delay-guaranteed multicast protocol is proposed to determine a multicast tree for real-time applications in multi-rate MANETs. In the proposed protocol, a method for estimating one-hop delay is proposed first. In order to maximize the network capacity, the tree is determined by adopting the strategy of minimizing the sum of the total transmission time of the forwarders and the total blocking time of the blocked hosts. Simulation results show that the method is more accurate in estimating one-hop delay and the proposed protocol obtains higher network capacity than previous works.
