Performance analysis of wireless sensor networks assisted by on-demand-based cloud infrastructure

Abstract

The wireless sensor networks composed of tiny sensor with the capability of mon- itoring the tangible changes for a wide range of applications are limited with the capabilities on processing and storage. Their limited capabilities make them seek the help of the cloud that provides the rented service of processing and storage. The dense deployment of the wireless sensor and their vulnerability to the unknown attacks, alterations make them incur difficulties in the process of the conveyance causing the modifications or the loss of the content. So, the paper proposes an optimized localization of the nodes along with the identification of the trusted nodes and minimum distance path to the cloud, allowing the target to have anytime and anywhere access of the content. The performance of the cloud infrastructure-supported wireless sensor network is analyzed using the network simulator 2 on the terms of the forwarding latency, packet loss rate, route failure, storage, reliability, and the network longevity to ensure the capacities of the cloud infrastructure-supported wireless sensor networks.
