1. A method comprising: measuring cumulative mesh network viability, based upon at least one server calculated packet loss information, from packets transmitted from at least one of a plurality of nodes, wherein a wireless network is an ad hoc wireless network and the packet loss information is calculated by: 
 P k+1 =P k +( C−L− 1) where P K =total packet loss calculated in a previous period, P K+1 =total packet loss calculated in a current period, C=packet count in the current period, and L=packet count in the previous period.
