In this paper, we proposed a simple yet novel multicast scheduling scheme for IEEE 802.16e wireless metropolitan area networks. Specifically, we want to solve the problem that how the base station schedules the data in a multicast superframe such that mobile stations can receive their required multicast data and the total awake time of mobile stations is minimal. We first prove that this problem is...
Based on the relations of the QoS parameters in wireless ad hoc networks, we proposed a new route found mechanism. The new mechanism calculate the length of the routing, the throughput require of the data transmit as bandwidth, and by the most of the bandwidth require to resource reservation to meet the QoS. Simulation result shows that it can meet the QoS require if the network allow.
We propose a routing mechanism with distributed call admission control (CAC) algorithms for mobile ad hoc networks (MANET) based on IEEE 802.11e EDCA MAC protocol. A new flow can be admitted by the network only if it can find a path to sustain its traffic. Bloom filter is used here to detect the flows via each node, and the CAC routing decisions are made according to the number of flows of each node...
