Claim Text:
1. A method for selecting an edge-server set from a plurality of edge servers in a wireless network, comprising: constructing a trellis having a number of states equal to a number of edge servers in the edge server set, wherein each state comprises a plurality of nodes, each node corresponding to one of a plurality of candidate edge servers; and employing a trellis-exploration algorithm to select the edge-server set, comprising providing interconnects between each node of a first state to each of a plurality of nodes in a next state, and for each node in a state, selecting a path corresponding to a best performance metric that connects to a node in a previous state, wherein each performance metric comprises a network topology state based on channel-quality measurements and wherein at least one of the plurality of candidate edge servers is selected based on which clients a candidate edge server can reach using peer-to-peer wireless links.
