Abstract -
In wireless sensor-actor networks, sensors probe their surroundings and forward their data to actor nodes. Actors collect sensor data and perform certain tasks in response to various events. Since actors operate on harsh environment, they may easily get damaged or failed. Failed actor nodes may partition the network into disjoint subsets. In order to re-establish connectivity nodes may be relocated to new positions. This paper focus on review of three (LeDir, RIM, DARA) node recovery algorithms, and their performance has been analysed in terms network overhead and path length validation metrics.
