Speeding Up Bluetooth Mesh

Bluetooth has constantly evolved from its cradle in 1997 to the last 5.2 version 2020. With each update and amendment, it gained speed, range, versatility. One of latest introductions was Mesh Profile (BMP) making a technology suitable for wide variety applications. Nevertheless, BMP designed maintain compatibility with 4 devices already deployed market. This imposes some restrictions that place under other competing technologies like Zigbee or Thread terms throughput performance. In this paper we propose two mechanisms overcome these limitations take advantage new extended advertising capabilities introduced 5. These are presented as modifications current protocol stack allow transmission larger data structures. Thus, is possible boost more demanding applications like, example, image transmission. The first proposal an adaptation layer avoid modifying standard form. second makes minimal changes frame structure at different layers enabling user accommodate encapsulations (i.e., tunneling) without incurring IPv6-layer fragmentation. We have analyzed both solutions compared them throughput, delay, energy consumption channel conditions network size. results show except very small messages poor proposals improve delay BMP.
