LR-Seluge: Loss-Resilient and Secure Code Dissemination in Wireless Sensor Networks
—Code dissemination in wireless sensor networks refers to the process of disseminating a new code image via wireless links to all sensor nodes after they are deployed. It is desirable and often necessary due to the need for, e.g., removing program bugs and adding new functionalities in a multi-task sensor network. A sound code dissemination scheme need be both loss-resilient and attack-resilient, which are crucial for sensor networks deployed in lossy and hostile environments. To the best of our knowledge, no existing scheme simultaneously satisfies both requirements. This paper fills this gap with the design and evaluation of LR-Seluge, a novel lossresilient and secure code dissemination scheme. The efficacy and efficiency of LR-Seluge are confirmed by both theoretical analysis and extensive simulation results. In particular, LRSeluge can reduce up to 40% communication overhead in lossy environments with the same level of attack resilience in contrast to existing schemes. Keywo...
