In wireless ad-hoc networks, network partitioning occurs when the mobile nodes move with diverse patterns and cause the network to
separate into completely disconnected portions. Network partitioning is a wide scale topology change that can cause sudden and severe
disruptions to ongoing network routing and upper layer applications. Its occurrence can be attributed to various reasons like node getting
overloaded, broken, selfish, malicious and hand off (Graceful and Abrupt leave) etc. The objective of this paper is to propose a mechanism by
name Destitute Node Collaborative Cure Culminating to Continued Connectivity (DNC5) and Network Partition Panic Packet (NP3) which
underpins the creation of two lists namely Core Routing List (CRL) and Backup Routing List (BRL) for any sender – receiver pair. The
intermediate node causing network partition/divide under the influence of the attacker offers seamless interconnectivity through this innovative
technique. This solution encourages the activation of BRL in absence of the CRL service to guarantee faultless/flawless network routing service
in ad hoc network. The destitute nodes which are deprived of the network service due to network split unite/collaborate in desecrating the culprit
node to cure the network split and render uninterrupted network activities. The proposed solution offer remote opportunities for the
orchestration of network partition in ad hoc network. Suitable graphs have been simulated to accentuate the finding with judiciously considered
