An initiator node in a local cluster included in a wireless network receives an admission request to execute an application comprising a set of tasks. If the initiator node is unable to map the set of tasks to nodes included in the local cluster, the local cluster head node forwards the admission request to the cluster head node of successive clusters in the wireless network in order to have at least one node in each of the successive clusters send resource availability information to the initiator node. The initiator node attempts to map the set of tasks to a subset of the nodes from which resource availability information has been received. This is repeated until the initiator node is able to map the set of tasks to a subset of the nodes in the wireless network or until there are no additional clusters to forward the admission request to.
