A cross-layer routing algorithm based on new channel bandwidth estimation method

To overcome the problem of network performance degradation and throughput reduction as a result of link interferences in multi-channel network, it proposes a cross-layer routing algorithm based on new channel bandwidth estimation method. To start from the direct representation of channel interferences, i.e. channel idleness, the algorithm uses a new and more accurate channel idleness ratio estimation method as basis. Based on channel serviceable condition, it avoids channel interferences and improves performance of network.
