Abstract
This paper explores the challenges and constraints when over the horizon (OTH) maritime surveillance service utilizes an Internet of Things (IoT) as its backbone. The service is based on High Frequency Surface Wave Radars (HFSWRs) and relies on a satellite communication network as its communication infrastructure in harsh environments. The complete IoT OTH maritime surveillance network is currently deployed in the Gulf of Guinea, which due to its tropical climate represents an unfavorable environment for sensors and communications. In this paper, we have examined the service performance under various meteorological conditions specific to the Gulf of Guinea. To the best of our knowledge, this is the first analysis of IoT OTH maritime surveillance service in equatorial environment. Our analysis aims to mathematically describe the impact of harsh weather conditions on the performance of the service in order to mitigate it with careful overall system design and provide constant quality of the service. Analyses presented in the paper show that average service latency is about 90 s, but it can rise to about 120 s, which is used as a key information during the sensor data fusion algorithm design. Validity of the analyses is demonstrated through high quality of service with an outage probability of just 0.1% in the driest months up to the 0.7% in the rainiest months. The work presented here can be used as a guideline for deployment of maritime surveillance service solutions in other equatorial regions. Moreover, the gained experience presented in this paper will significantly facilitate future expansions of the existing maritime surveillance network with more HFSWRs. This will be done in such a way that it will not affect the quality of service of the entire system on a large scale.

Summary
Piracy represents a growing trend, especially in the less regulated international waters, such as South-East Asia, East and West Africa and Caribbean [1]. Under the IoT OTH maritime surveillance service we consider the raw data gathering from the open sea, data processing by HFSWRs at remote sites and, at the end, the data transfer to the server on a Command and Control Center (C2) location, via the satellite network. OTH maritime surveillance service, based on HFSWRs, that uses satellite communications as the communication backbone in the equatorial region (the Gulf of Guinea). The experience gained of 19 from the deployed operating maritime surveillance network and analysis provided in this paper can be used to design and deploy similar systems in other equatorial regions of the world.
