摘要： A method of characterizing transmission of a node of a wireless network is disclosed. The method includes determining a neighbor function based on how many neighboring nodes are affected by a neighbor function based on how many neighboring nodes are affected by signals transmitted from the node at varying power levels. For a range of transmission path losses between the node and neighboring nodes, transmission power levels and transmission data rates are calculated that minimize an air-time metric, wherein the air-time metric is dependent on the neighbor function and an air-time occupied by transmission packets.

摘要： An apparatus and method of determining throughput between a first host and a second host of at least one network is disclosed. The method includes the first host intentionally corrupting ICMP packets by manipulating a checksum of the ICMP packets. The first host sends the corrupted ICMP packets to the second host through the at least one network. The first host additionally sends non-corrupted ICMP packets to the second host. Based on responses from second host to the ICMP packets, the first host estimates a throughput between the first host and the second host. The throughput includes a first direction throughput from the first host to the second host, a second direction throughput from the second host to the first host, and a round trip throughput between the first host and the second host.
