Vehicle network address assignment
A first computer is connected to a communication network and is assigned a first network address on the communication network. A second computer is connected to the communication network and is assigned the first network address on the communication network. A first message, including the first network address and a request to generate a random number, is transmitted by the first computer via the communication network. A first reply message, including the random number, is received from the second computer in response to the request. A second network address is assigned for the second computer by the first computer based on the random number. A second message, including the second network address and the random number, is transmitted by the first computer via the communication network.
1 . A system, comprising:
a communication network;
a first computer connected to the communication network and assigned a first network address on the communication network; and
a second computer connected to the communication network and assigned the first network address on the communication network;
wherein the first computer is programmed to:
transmit, via the communication network, a first message including the first network address and a request to generate a random number;
receive a first reply message from the second computer including the random number in response to the request;
assign a second network address for the second computer based on the random number;
transmit, via the communication network, a second message including the second network address and the random number;
transmit, via the communication network, a third message including the second network address and a second request to confirm the second network address;
receive a second reply message from the second computer including the second network address in response to the third message; and
upon receiving, via a short-range broadcast protocol, the second reply message, determine a location of the second computer based on at least one of an angle-of-arrival measurement, a signal strength measurement, or a time-of-flight measurement of the second reply message.
2 . A method, comprising:
at a first computer, transmitting, via a communication network, a first message including a first network address and a request to generate a random number;
receiving a first reply message from a second computer including the random number in response to the request;
assigning a second network address for the second computer based on the random number;
transmitting, via the communication network, a second message including the second network address and the random number;
transmitting, via the communication network, a third message including the second network address and a second request to confirm the second network address;
receiving a second reply message from the second computer including the second network address in response to the third message; and
upon receiving, via a short-range broadcast protocol, the second reply message, determining a location of the second computer based on at least one of an angle-of-arrival measurement, a signal strength measurement, or a time-of-flight measurement of the second reply message.
3 . A system, comprising:
a communication network;
a first computer connected to the communication network and assigned a first network address on the communication network; and
a second computer connected to the communication network and assigned the first network address on the communication network;
wherein the first computer is programmed to:
transmit, via the communication network, a first message including the first network address and a request to generate a random number;
receive a first reply message from the second computer including the random number in response to the request;
assign a second network address for the second computer based on the random number;
transmit, via the communication network, a second message including the second network address and the random number;
transmit, via the communication network, a third message including the second network address and a second request to confirm the second network address;
receive a second reply message from the second computer including the second network address in response to the third message; and
upon receiving, via the communication network, the second reply message, determine a location of the second computer based on an amount of time to receive the second reply message after sending the second request.
4 . A method, comprising:
at a first computer, transmitting, via a communication network, a first message including a first network address and a request to generate a random number;
receiving a first reply message from a second computer including the random number in response to the request;
assigning a second network address for the second computer based on the random number;
transmitting, via the communication network, a second message including the second network address and the random number;
transmitting, via the communication network, a third message including the second network address and a second request to confirm the second network address;
receiving a second reply message from the second computer including the second network address in response to the third message; and
upon receiving, via the communication network, the second reply message, determining a location of the second computer based on an amount of time to receive the second reply message after sending the second request.
