MULTICAST CAPACITY IN UNIFORMLY DENSE NETWORKS BY AD HOC ROUTING

A rapid development in wireless ad hoc networks, in both academic and industrial fields. The optimal scheduling, routing and relaying of packets, the per-node capacity still decreases as Θ(1/√ n) when n approaches the infinity. Many studies try to improve this disappointing scalability of throughput capacity by introducing different characteristics into ad hoc networks, such as mobility of nodes, an infrastructure of the network: a multicast transmission scheme. Infrastructure in an ad hoc network provides a more straightforward increase to the capacity. claim that infrastructure can offer a linear capacity increase in a hybrid network, when the number of base stations increases asymptotically faster than √ n. Multicast transmission refers to the transmission from a single node to other k − 1 nodes, so as to generalize both unicast and broadcast transmissions. Many existing studies focus on the combinations of the above characteristics. Some aim to further increase the network performance, while others try to present a more realistic scenario. Explore the multicast capacity in a static hybrid network with infrastructure support. The effects of mobility and infrastructure in multicast capacity of a wireless mobile ad hoc network. We divide mobility into three regimes, and present reachable upper bounds and lower bounds for each regime. Multicast capacity in a more realistic network model featuring both mobility and infrastructure support. A result, our work generalizes both unicast and broadcast capacity results in MANETs and hybrid networks.
