Network Node and Methods in a Mesh Network

A method performed by a first network node, for reducing the number of colliding transmissions in a mesh network, wherein the first network node and a second network node operate in the mesh network, and wherein the first network node and the second network node are configured to use periodic advertising for transmissions in the mesh network, the method comprising:

• calculating, a first duration, wherein the first duration relates to a transmission of data of a first size, to be transmitted to the second network node;
• calculating a second duration, wherein the second duration relates to a period of time until a reception or transmission of data scheduled for the second network node will occur;
• based on the first duration and the second duration, deciding whether or not to decrease the first size of the transmission to a second size, so that the first duration becomes shorter than the second duration;
• and
• performing the transmission according to the outcome of the deciding.

A non-transitory computer readable medium storing a computer program for reducing the number of colliding transmissions in a mesh network, wherein a first network node and a second network node operate in the mesh network, and wherein the first network node and the second network node are configured to use periodic advertising for transmissions in the mesh network, wherein the computer program comprises instructions that, when executed by a processor of the first network node, cause the processor to:

• calculate, a first duration, wherein the first duration relates to a transmission of data of a first size, to be transmitted to the second network node;
• calculate a second duration, wherein the second duration relates to a period of time until a reception or transmission of data scheduled for the second network node will occur;
• based on the first duration and the second duration, decide whether or not to decrease the first size of the transmission to a second size, so that the first duration becomes shorter than the second duration;
• and
• perform the transmission according to the outcome of the decision.

A first network node configured for reducing the number of colliding transmissions in a mesh network, wherein the first network node and a second network node are operable in the mesh network, and wherein the first network node and the second network node are configured to use periodic advertising for transmissions in the mesh network, the first network node comprising:

• communication circuitry configured for communicating with one or more nodes in the mesh network;
• and
• processing circuitry operatively associated with the communication circuitry and configured to:
• calculate, a first duration, wherein the first duration relates to a transmission of data of a first size, to be transmitted to the second network node;
• calculate a second duration, wherein the second duration relates to a period of time until a reception or transmission of data scheduled for the second network node will occur;
• based on the first duration and the second duration, decide whether to decrease the first size of the transmission to a second size, so that the first duration becomes shorter than the second duration;
• and
• perform the transmission, via the communication circuitry, according to the outcome of the decision.
