Title: Optimized Monitoring of Internet of Things Networks

Abstract:

The emergence of the Internet of Things (IoT) is introducing more and more services and applications such as smart cities. IoT networks tend to experience unexpected communication problems during deployment, because resource-constrained embedded devices are unreliable by nature for a variety of reasons, such as uncertain radio connectivity and battery drain. Despite the fact that IoT networks are dynamic and vulnerable, the offered services need the continuous availability of defined network components. To that end, monitoring techniques for detecting, localizing and remedying network failures in IoT will definitely develop in significance. The objective of our work is to contribute to the optimization of IoT network monitoring for fault tolerance and quality of service purposes. We aim at the designing of optimized, efficient algorithms for monitoring of communicant elements in IoT networks. Additional monitoring will increase the network load; however, the added cost for link monitoring could be tolerated, especially for critical-time IoT applications. This is because monitoring will help in accelerating link recovery, and decreasing node unreachability times. Nevertheless, the monitoring algorithms must be optimized in order to minimize the energy requirements and the monitoring load. In previous work, we proposed a polynomial-time algorithm that aimed to achieve distributed probe/monitor placement with minimal computational complexity. The proposed algorithm works in tandem with RPL. The problem was modeled as a Minimum Vertex Cover Problem (VCP). Furthermore, we developed another optimization model for scheduling of the monitoring role of the nodes in IoT networks to maximize the lifetime of the resource-constrained embedded devices while minimizing the overall cost of monitoring in the network. The multi-phase model was tested on randomly generated instances and results proved to be very promising.
