Abstract

The sensor network is highlighted because it is one of the essentialbase networks in the ubiquitous computing realization. Researches for providing security and efficiency are being perfomed in the various isuues because of the characteristics of sensor nodes and sensor networks. Recently, code dissemination mechanism is recognized as an important research issue since sensor nodes are in the need of updating new software or the need of modifying bugs in dynamically. Generally lots of nodes are in the sensor networks and they are ramdomly deployed in hostile environments. Thus it is especially important that the code dissemination from the base station to nodes should be processed efficienctly and securely. In this paper, we check up the recent existing code dissemination mechanisms, and comparatively analyze the requirements of the code dissemination and the characteristicsof existing mechanisms. Through the analysis, we present future research issues for the code dissemination area. This research can expedite the research on the code dissemination and improve the usability of sensor networks with efficiency and security.
