Patent ID: 8050195

Claim:
A traffic performance evaluation system in a multi-hop wireless network comprising: a performance index estimation means for regarding the multi-hop wireless network as a combination of a plurality of single-hop wireless networks and estimating a traffic performance index of each node of the network; and a performance index determination means for determining a traffic performance index of the whole multi-hop wireless network based on an estimation result of all the nodes which is obtained by the performance index estimation means; wherein the performance index estimation means comprises: an extraction means for extracting a first node being within a radio wave reaching region of each of the nodes and a second node in a hidden terminal relation to each of the nodes based on information about the nodes being within the radio wave reaching region of each of the nodes and a network topology; and an estimation means for respectively calculating a transmission traffic amount of each of the nodes, a transmission traffic amount of the first node and a transmission traffic amount of the second node to each of the nodes, and estimating the traffic performance index of each node.
