Blocking control and dynamic exchange buffer switching new approach for mobile wireless sensor networks

Mobile sensor nodes are usually positioned in low battery power unattended surroundings. Wireless hypermedia sensor-based networks have a huge capacity and a continual flow of data from source to sink. The congestion emerges when the input amount exceeds the number of resources available. The effect of congestion is packet loss, buffer overflow, and waste of power, as well as increasing delays from end to end. The suggested dynamic alternating buffer technique for switching and management of the congestion, using the residual buffer, residual energy and sensor-mobile node confidence level, is applied to effectively control the congestion. The system is based on a cost-effectiveness analysis which calculates main and replacement buffers on time. The dynamic buffer shift is possible by this approach and the congest impact is optimized. The BETCC performance is compared to that of other current protocols such as TCEER and TFCC with respect to energy usage and data loss ratios. © 2021 Little Lion Scientific.
