Consider a general network with a set [??] of nodes and a set [??] of transmission links. We denote by N and L respectively the number of nodes and links in the network. Each link represents a communication channel for direct transmission from a given node a to another node b, and is labeled by its corresponding ordered node pair (a, b) (where a, b [member of] N). Note that link (a, b) is distinct from link (b,a). In a wireless network, direct transmission between two nodes may or may not be possible and this capability, as well as the transmission rate, may change over time due to weather conditions, mobility or node interference. Hence in the most general case one can ...
