Clock skew is defined as the rate of deviation of a device clock from the true time. The frequency of a device's clock actually depends on its environment, such as the tempera...
In energy constrained wireless sensor networks, energy conservation techniques are to be applied in order to maximize the system lifetime. We tackle the problem of increasing netw...
— Wireless reprogramming of a sensor network is useful for uploading new code or for changing the functionality of existing code. Through the process, a node should remain recept...
