A Flexible Enhanced Throughput and Reduced Overhead (FETRO) MAC Protocol for ETSI SmartBAN

Smart body area networks (SmartBAN) is an emerging wireless (WBAN) standard proposed by the European Telecommunications Standards Institute (ETSI). This paper first examines potential of SmartBAN medium access control (MAC) layer with scheduled to support a myriad WBAN applications, having diverse data rate requirements. Extra slots can be allocated high date sensor nodes for managing their High also re-assigned use available time low in Inter-Beacon Interval (IBI) central hub. But these two schemes incorporate different physical (PHY) and MAC overheads related frame transmission, acknowledgement slot re-assignment. redundant overhead transmission results energy consumption reduced effective throughput. Therefore, innovative flexible enhanced throughput (FETRO) protocol this article. In scheme, node requirements are considered while assigning duration allowing minimal changes base-line implementation. infers provision variable durations within IBI. We evaluate existing techniques extra allocation re-assignment as well FETRO length. The scheme optimizing both overall normalized per kilo bits second (Kbps). Additionally, impact various channel models over management approaches investigated. gives average reduction 65.5 59.16 percent, respectively, hub Kbps outcomes, compared de-facto scheduling strategies.
