SYSTEM AND METHOD EMPLOYING WIRELESS COMMUNICATIONS AND PREDETERMINED MEASUREMENT FUNCTIONS OF WIRELESS NODES FOR ASSESSING WIRELESS COMMUNICATION PERFORMANCE
First Claim
1. A system employing wireless communications and a plurality of test packets for assessing wireless communication performance, said system comprising:
- a first wireless node comprising;
a first wireless transceiver,a first memory storing a first schedule defining transmission and reception of a first set of said test packets by said first wireless transceiver, anda first processor cooperating with said first wireless transceiver and said first memory to transmit and receive the first set of said test packets responsive to said first schedule; and
a number of second wireless nodes, each of said number of second wireless nodes comprising;
a second wireless transceiver structured to wirelessly communicate with the first wireless transceiver of said first wireless node or with the second wireless transceiver of another one of said number of second wireless nodes,a second memory storing a second schedule defining transmission and reception of a second set of said test packets by said second wireless transceiver, anda second processor cooperating with said second wireless transceiver and said second memory to transmit and receive the second set of test packets responsive to said second schedule,wherein each of said first and second memories stores a corresponding predetermined application structured to employ some of said wireless communications, and a corresponding predetermined measurement function structured to measure wireless communication performance,wherein a corresponding one of said first and second schedules is executed by the corresponding predetermined measurement function,wherein each of said number of second wireless nodes is structured to be initialized, and to wait to receive a number of the second set of test packets before being synchronized with said second schedule and beginning to receive and transmit the second set of test packets according to said second schedule, andwherein said first and second processors are structured to store data from said first and second sets of said test packets, respectively.

Abstract
An embedded system includes a first wireless node and a number of second wireless nodes, each of which includes a wireless transceiver, a memory storing a schedule defining transmission and reception of test packets, and a processor transmitting and receiving the test packets responsive to the schedule. The memories store a corresponding predetermined application employing some of the wireless communications, and a corresponding predetermined measurement function measuring wireless communication performance. A corresponding one of the schedules is executed by the corresponding predetermined measurement function. The second wireless nodes wait to receive a number of the test packets before being synchronized with their schedule and receiving and transmitting the test packets according to their schedule. The processors store data from the test packets to assess wireless communication performance between corresponding nodes.
