QoS-driven wireless broadband home networking based on multihop wireless mesh networks

摘要

Wireless mesh networks are a suitable technology for wireless broadband home networks which can expand into ubiquitous networks. In this paper, we introduce a home network architecture which is based on the multihop wireless mesh networks and provide a general overview of the architecture. The system model introduced might be helpful to set up self-organizing and self-configuring network for consumer homes. The wireless mesh home network architecture can reduce the deployment cost and provide a much simpler deployment process by wireless home mesh routers. The home mesh routers provide various functions. Thus, home mesh router discovery and selection problems pose a primary challenge in the wireless mesh home network architecture. To deal with these problems, we propose a scoped-proactive home mesh router discovery scheme and a QoS-driven home mesh router selection mechanism. The scoped-proactive discovery protocol limits the flooding area. Among the candidates, a serving mesh router is selected based on a QoS-driven selection metric. Through simulations, we show that our schemes perform better than existing mechanisms in terms of various performance measures
