1. A hierarchical wireless network, comprising:
- a mesh backbone network portion that comprises a plurality of first nodes, wherein at least one of the plurality of first nodes is configured to exchange packets with at least another of the plurality of first nodes; and
a tree switching network portion, comprising;
one or more second nodes; and
one or more third nodes, wherein;
at least one of the one or more second nodes is configured to exchange packets with one of the plurality of first nodes,at least one of the one or more second nodes is configured to exchange packets with at least one of the one or more third nodes,at least one of the one or more third nodes is configured to exchange packets with one of the one or more second nodes, andat least one of the one or more second nodes and at least one of the one or more third nodes are configured to;
determine whether a receive buffer is full; and
in response to a determination that the receive buffer is full, discard packets stored in the receive buffer based on respective ages and respective importance levels of the stored packets.

Abstract
A hierarchical wireless network is provided with a mesh backbone network portion and a switching tree network portion. The mesh backbone network portion includes first tier nodes each having at least one wireless link to another first tier node. The first tier nodes execute a link-state protocol for routing packets. The switching tree network portion includes second tier nodes each having a single wireless link to one first tier node and at least one wireless link to one third tier node, and third tier nodes each having a single wireless link to one second tier node. The second tier and the third tier nodes execute switching rules for switching packets.
