In this paper, the authors present an efficient routing protocol for Mobile Hybrid Wireless Networks (MHWNs), which consists of an infrastructure wireless network and a few mobile ad hoc networks. MHWNs have several advantages over traditional wireless networks (such as cellular networks and WLANs). For example, MHWNs can achieve higher throughput, larger coverage, and better load balancing cross cells. In this paper, they present an efficient routing protocol for MHWNs. The protocol utilizes node location information, moving speed, and remaining battery life for routing decision. The protocol is energy efficient (for mobile nodes) and can find robust routing path. They evaluate its performance by NS-2 simulations. Their results show that the protocol significantly reduces the routing overhead, and the routing path is relatively stable.
