Loading program code to sensor nodes is a basic function of wireless sensor network. However, it is infeasible to gather all sensor nodes once they are deployed. Thus, network reprogramming is greatly required. In this paper, we present two improvement mechanisms to current network reprogramming approaches: the resident mechanism to reduce the size of binary code to be disseminated and stored, and the hierarchical full indexing with sliding window mechanism to record lost code capsules. Both mechanisms can reduce radio transmission and storage access, which are main consumers of energy and time. Accordingly, our mechanisms are energy-efficient and timesaving.
