Coexistence of heterogeneous wireless networks (HWNs) to provide ubiquitous service is an inevitable trend. Vertical Handoffs (VHOs) are crucial requirements for convergence of different access technologies. In this paper, a utility-based VHO decision algorithm is proposed. A profit function is used to calculate the profits gained from a VHO and to select the target network accordingly. Signaling...
The integration cellular networks, wireless local area networks (WLANs), and the new paradigm of mobile ad hoc networks (MANETs) is the trend for next generation mobile networks. And the multi-hop routing mechanism is an open and challenge issue in this area. In this paper, a multi-hop routing mechanism with fuzzy estimation of links for heterogeneous wireless networks (HWNs) is proposed. The mechanism...
