Publish/subscribe based reprogramming of sensor networks

Remote reprogramming of sensor nodes through wireless channel is a very important function for efficient sensor networks management. Now-a-days secure reprogramming protocols use asymmetric cryptography schemes which are in need of many computational cost and large memory. In this paper an efficient authentication strategy based on the publish/subscribe scheme for reprogramming of sensor networks is presented. By means of integrating this scheme with previous reprogramming protocol MNP, this strategy can ensure security of reprogramming at lower cost.
