Security and Energy Considerations for Routing in Hierarchical Optical Sensor Networks

In this paper we evaluate the energy and security consideration for a security-aware routing protocol proposed for uni-directional, hierarchical optical sensor network. We bootstrap the unconstrained resources of the base station to design GORA, a greedy optimized routing algorithm, in which the base station is responsible for network route optimization and updates. This paper extends our recent work on OPSENET, a novel and efficient protocol that facilitates secure routing in directional optical sensor networks. We evaluate security and energy metrics for our scheme proposed scheme. Analysis and simulation results are used to show the performance of our algorithm, compared with other hierarchical bi-directional clustering routing schemes
