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 of radio transmissions should be minimized, since reprogramming time and energy depend chiefly on the number of radio transmissions. In this article, we present a multihop incremental reprogramming protocol called Zephyr that transfers the delta between old and new software versions, and lets the sensor nodes… 

Efficient reprogramming of wireless sensor networks using incremental updates

This paper investigates the improvement of energy efficiency and delay of reprogramming, at low resource cost, as enabling technologies data compression and incremental updates are used.

Reprogramming hardware-software heterogeneous Wireless Sensor Networks

This work presents the case of a functionality sent between two different hardware nodes, one running ContikiOS and the other, FunkOS, and presents a solution for performing such functionality exchanges on different node hardware, each running under different operating systems.

Analytical model of coding-based reprogramming protocols in lossy wireless sensor networks

A high-fidelity analytical model based on Dijkstra's shortest path algorithm is presented to measure the completion time of coding-based reprogramming protocols and results show both the number of packets per page and the finite field size have significant impact on completion time.

A multi-hop incre- mental reprogramming protocol called Hermes that transfers over the network the delta between the old and new software and lets the sensor nodes rebuild the new software using the received delta and the old software.

Stream: Low Overhead Wireless Reprogramming for Sensor Networks

Stream pre-installs the reprogramming protocol as one image and the application program equipped with the ability to listen to new code updates as the second image, which significantly reduces the size of the program image.

A Remote Code Update Mechanism for Wireless Sensor Networks

This paper presents Multihop Over-the-Air Programming (MOAP), a code distribution mechanism specifically targeted for Mica-2 Motes and shows that a very simple windowed retransmission tracking scheme is nearly as effective as arbitrary repairs and yet is much better suited to energy and memory constrained embedded systems.
