Wireless Sensor Networks (WSNs) have emerged as a promising new technology to monitor large regions at high spatial and temporal resolution. The inherent nature of WSNs such as unattended operation, battery powered nodes, and harsh environments pose major challenges. One of the challenges is to ensure that the network is connected. The connectivity of the network can easily be disrupted due to unpredictable wireless channels, early depletion of node's energy, and physical tampering by hostile users. Network disconnection, typically referred as a network cut, may cause a number of problems.
