DYNAMIC RECONFIGURATION IN WIRELESS SENSOR NETWORKS

Dynamic reconfiguration for WSN is a field that attracts a lot of attention nowadays.There is interest in transmitting not only data, but also functionalities from one node to another. It is well established that this topic is a huge energy consumer during the RF communication between nodes. In-situ compi­ lation is the next obvious step in minimizing the transmission time between such nodes of a WSN, in the case of sending firmware updates or functionalities. Due to the low level of the bytecode for Virtual Machines in WSN, it implies a lot of instructions for the simplest of duties. Consequently, we have focused on building a new language, MinTax, and its corre­ sponding compiler. This will ensure prolonged node running time, by minimizing battery usage in areas of relatively fre­ quent firmware updates or functionality interchange. Our so­ lution, judging from a blink example, is twice as better better than the corresponding bytecode for Mate VM and around ten times better than the one for the Darjeeling VM.
