Sensor Network Evaluation dataset (ESPN 2020)

In recent years, the evolution of wireless communications and embedded systems have seen the birth of a new technology called wireless sensor networks. A wireless sensor network is a set of devices called sensors that can communicate with each other,collect information in their deployment areas and send it to the end user when needed. Typically deployed in hostile and inaccessible areas by humans, sensors must work unattended and securely send as much reliable information to the end user. Therefore,it becomes essential to ensure maximum coverage of the deployment area while warranting strong connectivity between sensors and safeguarding the security of information that passes through the network. Because of the low capacitance of the sensors in terms of battery power and computing power,the protocols to be implemented must be extremely light and energy efficient. In this paper, we focus on four major issues in wireless sensor networks (coverage, connectivity, energy conservation, and security)to propose a novel Efficient and Secured Protocol for wireless sensor Networks (ESPN). ESPNallows the sensors to collect more information in the deployment area, send them to the base station with high confidentiality and optimal energy consumption. ESPN consist of two algorithms subroutines(ESPN-sentinel, ESPN-guardian). ESPN-Sentinel (ESPNs) subroutine allows each cluster-head(CH) to know the path by which it sends the data to the base station, and ESPN-guardian (ESPNg)guarantees the confidentiality of the information circulating in the network. Overall, ESPN algorithm compared to the state of the art protocols emphasize 3 key innovations: (1) With the first subroutine(ESPNs), ESPN outperform the state of the art protocols with up to 3-fold difference on residual energy consumption (varies from 0.5% to 3.5% ), depending on the length of the path (number of hops) between the cluster-head and the base station. (2) The second subroutine (ESPNg) bring the state of the art cost from linear (e.g. o(n) where n is the node count) to constant cost (o(1)), for sensors communication andstorage requirement. (3) Finally, ESPN improved the security compare to the similar protocols in the same setting, and for a longer data transmission time, using its keys-renewal strategy.
