PINC: Pickup Non-Critical Node Based -Connectivity Restoration in Wireless Sensor Networks.

A Wireless Sensor Network (WSN) is connected if a communication path exists among each pair of sensor nodes (motes). Maintaining reliable connectivity in WSNs is a complicated task, since any failure in the nodes can cause the data transmission paths to break. In a -connected WSN, the connectivity survives after failure in any -1 nodes; hence, preserving the -connectivity ensures that the WSN can permit -1 node failures without wasting the connectivity.
