Network reprogramming is a way of reprogramming wireless sensor nodes by disseminating the program code over radio for uploading new code or for changing the functionality of existing code.. Existing reprogramming protocols, such as Deluge,achieve this by bundling the reprogramming protocol and the application as one program image, hence it increases the overall size of the image which is transferred through the network. This increases both time and energy required for network reprogramming. A proposed protocol divides the code image into application and reprogramming support. It pre-installs the reprogramming protocol as one image and the application program equipped with the ability to listen to new code updates as the second image that mitigates the above problem.
