packet routing based on channels bandwidth and number of hops
... The weights of edges are based on node bandwidth. Let us call such weight - metric 1 (M1). The disadvantage of the above described approach is that the packet transportation path takes into account only one network parameter (bandwidth by default). However, it is possible that for other criteria cho ...
