Abstract Restricted by the energy storage capability of sensor nodes, it is crucial to jointly consider security and reliability in data collection of Wireless Sensor Networks (WSNs). Challenging deployment environments with severe resource constraint sensors pose intricacies in reliable and secure data transmission for these networks. Under the more practical assumption, we propose an “Opportunistic Multipath Secure Routing Protocol (OMSRP)”, a novel security mechanism to support secure data transmission at the same time respecting the network restrictions in terms of energy. In this approach, data packet is split into several shares and transmitted along independent node-disjoint paths. Since the shares follow the multiple paths, even if one node is compromised, remaining data shares will follow other random paths, so the entire data cannot be hacked by the adversaries. During route discovery process, OMSRP employs Coalition Game Theory for angular dispersive node selection. A “best” angular dispersive node (candidate to forward the share) is chosen for each regional node which helped to create private tunnels (secured paths) for multiple shares to reach the destination. In order to realize more flexible reconfiguration and high-performance processing, the proposed method supports on-demand reprogrammable sensor nodes (behavior or functionality of sensor nodes changes as on-demand basis) to enable greater advantages in performing complicated tasks effectively. Simulation results demonstrate that our proposed OMSRP scheme using reprogrammable sensor is highly efficient in enhancing data transmission in WSNs. Further to which the experimental analysis proved that we were able to control energy depletion and prolong network lifetime using the proposed scheme.
