d wireless protocols such 802.11b and 802.11g. Self-organizing-Each node of a mesh network works out the routing for itself. Dynamic routing-A mesh network does real-time reconfiguration in response to additions, failures, or load changes. Resilient-A mesh network automatically reroutes around blockages in real-time, offering greater stability in the face of changing conditions or fail- ure at single nodes. Wide range of operation-Multihop networks extend the wireless range around obstacles and over greater distances. Wide range of applications-A mesh network supports a wide variety of meshes, from macromeshes suitable for metro area deployments to the micromeshes that dominate in the realm of sensor-based, telemetry, and control applications. Scalable deployment-The routing configuration in a mesh network is automatic; there is no exponential rise in complexity as the number of net- work nodes grows. Organization and business models-The decentralized nature of mesh networks lends itself well to decentralized ownership models, where each participant in the network owns and maintains its own hardware. WLANs Low power consumption-Substrate nodes can be deployed as completely autonomous units with solar power, wind power, or hydropower. In addition to these benefits of mesh networking, there are also a number of considerations, including the following: Unpredictable throughput-Throughput is dependent on the number of hops and is not predictable. WAP dependency- The further you get from the WAP, the lower the data rate. Scalability-A wireless mesh network's scalability depends on the number of radios in the WAP. Uncertain reliability-Reliability is uncertain in less than a full mesh. QoS-QoS remains a critical problem to resolve. Proprietary technology-Many prestandard vendors continue to emerge in Wi-Fi and WiMax. Wireless mesh solutions involve some proprietary tech- nology, so it is not always possible to mix WAPs from different vendors. Radio interference-Radio interference is a potentially significant issue when
