An Efficient Data Delivery Mechanism by Exploring Multipath Routes for Wireless Sensor Networks

Zhiqiang Ruan and Xingming Sun
This paper study the data delivery mechanisms that can with high probability thwarting node capture attacks in unattended or distributed wireless sensor networks. Classic cryptographic approaches are vulnerable to such attacks, mainly due to their deterministic nature. Because once the adversary compromises the sensor nodes, it can acquire the credential as well as the data collected and held by sensors. Furthermore, the adversary can easily insert bogus sensor readings or change the processing results and then use these keys to authenticate forged information. This study proposes and analyzes the application of Reed-Solomon (RS) codes to address the problem. In the proposed scheme, each sensor node encodes the original data into multiple redundancy data shares by applying predefined (n, k) RS codes and applies non-uniform allocation through multiple node-disjoint paths to the destination. Analysis and simulation results demonstrate that the proposed scheme is efficient and resilient against node capture attack.
