View of wireless sensor network (WSN) devices is small but have exceptional\nfunctionality. Each node of a WSN must have the ability to compute and\nprocess data and to transmit and receive data. However, WSN nodes have limited\nresources in terms of battery capacity, CPU, memory, bandwidth, and\ndata security. Memory limitations mean that WSN devices cannot store a lot\nof information, while CPU limitations make them operate slowly and limited\nbattery capacity makes them operate for shorter periods of time. Moreover,\nthe data gathered and processed by the network face real security threats. This\narticle presents an Adaptable Resource and Security Framework (ARSy) that\nis able to adapt to the workload, security requirements, and available resources\nin a wireless sensor network. The workload adaptation is intended to\npreserve the resource availability of the WSN, while the security adaptation\nbalances the level of security with the resource utilization. This solution makes\nresources available on the basis of the workload of the system and adjusts the\nlevel of security for resource savings and makes the WSN devices work more\nefficiently.
