Wireless reprogramming of sensor nodes is an essential requirement for long-lived networks since software functionality needs to be changed over time. During reprogramming, the number radio transmissions should minimized, time and energy depend chiefly on transmissions. In this article, we present a multihop incremental protocol called Zephyr that transfers delta between old new versions, lets rebuild using received software. reduces size by application-level modifications mitigate effects function shifts. Then it compares two binary images at byte level generate small delta, then sent wireless network all nodes. For wide range change cases used as benchmarks, 1.83 1987 times less traffic through than Deluge (the standard nonincremental TinyOS) 1.14 49 existing Jeong Culler [2004].
