SDAW: Secure Data Aggregation Watermarking-based Scheme in Homogeneous WSNs

In the recent days, many researchers have focused on securing this paradigm despite the constraints it imposes such as the limited resources. Most of the solutions proposed to secure the data aggregation process in WSNs are essentially based on the use of encryption keys to protect data during their transmission in the network. Indeed, the key generation and distribution mechanisms involve additional computation costs and consume more of energy. Considering this, in this paper, we propose a new security mechanism to secure data aggregation in WSNs called SDAW (secure data aggregation watermarking-based scheme in homogeneous WSNs). Our mechanism aims to secure the data aggregation process while saving energy. For this, the mechanism uses a lightweight fragile watermarking technique without encryption to insure the authentication and the integrity of the sensed data while saving the energy. The links between the sensor nodes and the aggregation nodes, and also the links between the aggregation nodes and the base station are secured by using the watermarking mechanism.
A Cross-Layer Watermarking-Based Mechanism for Data Aggregation Integrity in Heterogeneous WSNs

In this paper, we propose an efficient watermarking based security strategy to ensure data aggregation integrity in heterogeneous WSNs. The proposed security scheme suggests a new fragile watermarking technique based on a dynamic embedding mechanism and a cross-layer approach. Compared to the existing heterogeneous security solutions, our system respects the resources limitations of the homogenous sensor nodes and optimizes the data aggregation process on the heterogeneous aggregation nodes. The proposal is evaluated using simulation.
A Cross Layer Communication Protocol with Transmission Power Adjustment for Energy Saving in Multi-hop WSNs
Introducing a cross-layer scheme to optimize energy consumption in multi hop wireless sensor netw... more Introducing a cross-layer scheme to optimize energy consumption in multi hop wireless sensor networks (MhWSNs) is a relatively new approach. Moreover and contrarily to the existing cross-layer MhWSNs architectures, this paper deals with a new cross-layer design based on three-ware cross-layer architecture which exploits an inversed interaction between network, link and physical layers. We propose a cross-layer and hybrid energy efficiency protocol (named CL-HEEP) with transmission power adjustment to preserve the energy reserves in multi-hop MhWSNs. The main idea is the use of routing information to dynamically adjust the transceiver transmission power and to establish cross-layer duty-cycling. An additional wake-up radio is also implied by CL-HEEP to preserve the energy while avoiding compulsory wake-up, idle listening, interference, and collision problems. The simulation reveals that CL-HEEP is energy-efficient and able to achieve significant performance improvement compared to other cross-layer protocols.
