Abstract: Wireless Sensor Network Comprise of Some Tiny sensing hubs which are outlined to work in a targeted locale. Coverage conservation is an ultimate necessity of remote wireless sensor networks to effectively convey certain services. Sensing hubs are equipped with constrained battery power that’s a major concern in this field. Amid network working, a few of the sensing hubs get pass on since of energy exhaustion which can create a specific region unattended. We allude this unattended region as coverage gap. A few other reasons for coverage gap are hub failure, link miscarriage etc. We propose a Coverage Gap Discovery and Reclamation (CGDR) algorithm as solution for this coverage gap issue. CGDR uses location coordinates of deployed hubs to identify and reclaim those coverage gaps. Performance evaluation shows that our proposed algorithm performs better in terms of gap discovery time and number of hubs required for its reclamation. CGDR can ensure full coverage reclamation for all kind of convex and non convex gaps of the network.
