This paper gives a clear definition of WH's seamless roaming, and points out the limitation of IEEE802.11 infrastructure mode for WH's mobility in multihop Ad hoc network.
This algorithm considering the limitation of node energy, network connectivity, no repetitive, node mobility, using the minimum nodes in order to get no blind of area coverage.
The implementation of the protocol overcomes the limitation of wireless bandwidth and high mobility, improves the performance and the destruction resisting capacity of the network.
