Wireless network configuration

In this section, we explore a wireless network configuration battery-aware alternative to Gnutella's mechanism for selecting ultrapeers. Our algorithm favors selection of supernodes that are likely to be plugged in, and attempts to avoid choosing supernodes that will be unplugged for any portion of their session. Our results indicate that this algorithm nearly always selects nodes that will remain plugged in for the entire period they serve as a supernode.
