The routing capacity region of networks with multiple unicast sessions can be characterized using Farkas' lemma as an infinite set of linear inequalities. In this paper this result is sharpened by exploiting properties of the solution satisfied by each rate-tuple on the boundary of the capacity region, and a finite description of the routing capacity region which depends on network parameters is offered...
Network coding is a new method by which a multicast network can achieve the network capacity determined by the max-flow and min-cut theorem. This paper shows the mutual exchange of independent information between two nodes in a wireless network which can be efficiently combined with network coding and broadcast property offered by wireless medium. It introduces COPE, an opportunistic approach to network...
