one gateway in Wireless Mesh Network

Because there is always not only one gateway in Wireless Mesh Network, other gateways can also be used to communicate with Internet. The wireless chi dazzle terminal is mapped to several gateways, and data stream can select the rational gateway and path to route. Meanwhile, the multi-path routing is based on data packet. This Multi-Gateway and Multi-Path routing protocol dramatically increases the degree of parallelism and improves the efficiency of the ralph lauren polo shirts network.After the investigation of the traditional terminal handoff Lacoste Polo Shirts strategy, we divide the situation of terminal handoff to internal handoff and external handoff, and use two different handoff strategies to handle them. Internal handoff has a higher priority and lower handoff delay and overhead than external handoff. An external handoff will be triggered when the internal handoff cannot be nike shox shoes occurred. Although, external handoff has higher handoff delay and overhead, it can make sure the data stream not being interrupted. The combination of two handoff strategies not only brings down the cheap wedding dresses 2010 handoff delay, but also reduces the average network overhead. There is no centralized management mechanism in Wireless Mesh Network; the change of network topology is also out of control. The traditional method to dealing with the change of network topolohy is link-aware and routing update.
