Abstract:
Wireless Sensor Networks Running (WSN) functionality depends critically on the network connectivity. The connectivity is generally determined by the node density and the nodes’ transmission range. However, the applied routing protocol decides the routing path topology. A failing node may disrupt the current path topology such that dedicated recovery methods are needed to ensure a loop-free reconnection of the disconnected nodes. In this article, we estimate the probability that disconnected nodes need dedicated recovery methods in networks where the nodes are randomly located and which use RPL as routing protocol. We further calculate the success rate and overhead cost for different RPL fitted recovery protocols to better judge where the different methods should be used.
