Motivation 上降充通大 SHANGHAI JIAO TONG UNIVERSITY Network with multicast traffic pattern can also be regarded as clustered network since nodes of the same multicast session compose of a cluster. >Sensor Network >Military Battle Field surface sink tellite onshore sink station surface sink surface station cluster uw-sink vertical link horizontal multi-hop link
Objectives 上游通大￥ SHANGHAI JIAO TONG UNIVERSITY The network heterogeneities investigated in prior works are inadequate for exploring the clustering behavior of such network. What are the new features of such network? Heterogeneous Cluster Traffic (HCT):Clients of the same cluster(data flow)are likely to be deployed around a cluster head specified by an Inhomogeneous Poisson Process(IPP). Heterogeneous Cluster Size(HCS):Clusters may have different size(cardinality)and HCS is employed to describe the population variation for each multicast data flow
Objective 上降充通大 SHANGHAI JIAO TONG UNIVERSITY What are the impacts of heterogeneous cluster traffic and size on multicast capacity in static network? Heterogeneous cluster traffic increases network capacity for all the clusters. Heterogeneous cluster size does not influence the network capacity
