In a software defined network (SDN), it is usually required to frequently collect state/statistics of all the flows, which may result in large overhead on control links. To reduce the flow re-routing overhead, we perform load-balanced routing using the traffic knowledge by carefully taking flow statistics collection. A key challenge for achieving effective almost-optimal load-balanced routing with...
In this paper, we consider hybrid wireless networks with a general node density λ∈[1,n], where n ad hoc nodes are uniformly distributed and m base stations (BSs) are regularly placed in a square region A(n,A)=1,A×1,A with A∈[1,n]. We focus on multicast sessions in which each ad hoc node as a user chooses randomly d ad hoc nodes as its destinations. Specifically, when d=1 (or d=n−1), a multicast session...
