OS-based reprogramming techniques in wireless sensor networks: A survey

Wireless sensor networks (WSNs) usually operate over long periods of deployment in places hard to be reached by human. Reprogrammability is essential to achieve flexible WSNs that have already been deployed in field and in use. Code dissemination techniques are necessary for reprogramming a WSN. In this paper, we give a survey on existing OS-based approaches for reprogramming WSNs, and discuss related research issues and trends in this area.
