Mobile sensor networks rely heavily on inter-sensor connectivity for collection of\r\ndata. Nodes in these networks monitor different regions of an area of interest and collectively\r\npresent a global overview of some monitored activities or phenomena. A failure of a sensor\r\nleads to loss of connectivity and may cause partitioning of the network into disjoint segments.\r\nA number of approaches have been recently proposed that pursue node relocation in order\r\nto restore connectivity. DCR is a distributed partitioning detection and connectivity restoration\r\nalgorithm to tolerate the failure of sensors. DCR proactively identifies sensors that are\r\ncritical to the network connectivity based on local topological information, and designates\r\nappropriate, preferably non-critical, backup nodes. Upon failure detection, the backup sensor\r\ninitiates a recovery process that may involve coordinated relocation of multiple sensors. Here\r\nwe proposed Energy aware Distributed partitioning detection and connectivity restoration algorithm\r\n(EDCR) that is an improvement of DCR algorithm. Therefore reducing the message\r\nexchange overhead, lower energy consumption, and thus will increase the network lifetime.
