Abstract

Over the Air Programming (OTAP) is the wireless reprograming of sensor nodes for wireless sensor networks (WSN). Methods of OTAP called code dissemination techniques strive to reduce reprogram time which saves on power and network downtime. A few leading approaches are Sprinkler, Firecracker, Deluge. A comparison of two Sprinkler approaches along with a Firecracker and Deluge approach has been simulated and presented by this paper. The comparison reveals the advantage of Deluge being a self-arbitrated protocol over Sprinkler and Firecracker's gateway arbitration. The metric of performance is the amount of time to reprogram a randomly deployed WSN of varying size. This paper focuses on analysing and modelling these dissemination methods with results showing effect of network size on each technique. The random deployment of nodes offers a rare insight to the generic performance of each method. Results show Deluge to be the fastest method with a growing advantage as size of a network increases. A network of 500 nodes shows Deluge to have a 98% time advantage over Sprinkler and 80% advantage over the Firecracker method as implemented. A suggested combination of Deluge and MNP being an advanced form of Firecracker is put forward as future work showing combinations of arbitration techniques can improve performance.
