Abstract: Wireless sensor networks have found their applications in numerous industrial fields. This is because they assist humans by ceaseless monitoring of impossible areas by sending timely updates to the base station. Once these sensors are set up, it is highly impossible for humans to manually reprogram such devices and hence a reprogramming protocol is a necessity here. Such a reprogramming process needs to be done in an energy efficient way. This paper we propose Distributive Reprogramming of sensor nodes with secure Data Transmission where the nodes are categorized into good and bad nodes during the forwarding process of the reprogramming code. Also a random key generation and exchange is proposed and used between the nodes in this work to further improve security. Also the allocation of the Users in SDRP is a significant task as the failure of the User Node might cause the failure of the entire group of nodes under that particular User. Considering the energy of each wireless sensor node the allocation of the users can be done to enhance the overall energy efficiency of the SDRP without altering the multi-authorization of the network. It is an enhancement over Secure and Distributive reprogramming protocol and has been proved through network simulator simulations to show greater quality of service on Energy, Packet loss, Delay and throughput than the existing scheme.
