RECD: A reliable and efficient code distribution protocol for network reprogramming

In this paper we propose a multihop code distribution protocol RECD which is reliable and efficient. We use an epidemical algorithm to guarantee the haleness and integrality of the distribution.To extend the life of network, reducing energy consumption and improving radio channel utilization, we propose a sender selection mechanism that make tradeoff between energy and influence. Further we introduce sleep mechanism during distribution to reduce the radio active time of idle node. Finally, we argue that do the CRC check in the packet level can obviously reduce the read/write frequency of EEPROM, accordingly reduce energy consumption.
