An Application of Multipath Routing for Intrusion Tolerance in HWSNs

The various multipath routing wireless sensor networks uses multipath routing to answer user queries in the presence of defective and malicious nodes. The fixed method uses a novel probability model to analyze the best redundancy level in terms of path redundancy (mp) and source redundancy (ms), as well as the best interruption detection settings in terms of the number of voters (m) under which the lifetime of a heterogeneous wireless sensor network is maximized while satisfying the reliability, timeliness and security, so the above problem can be solved using packet modifier and packet sniffing attack, by making use of Shamir secret sharing algorithm and by adding checksum. In this paper we propose an aplication of heterogeneous wireless sensor networks (HWSNs), utilizing multipath routing to answer user queries in the presence of unreliable and malicious nodes. The key concept of our redundancy management is to exploit the tradeoff between energy consumption vs. the gain in reliability, timeliness, and security to maximize the system useful lifetime. We formulate the tradeoff as an optimization problem for dynamically determining the best redundancy level to apply to multipath routing for intrusion tolerance so that the query response success probability is maximized while prolonging the useful lifetime.
