An NS-3 Implementation and Experimental Performance Analysis of IEEE 802.15.6 Standard under Different Deployment Scenarios

Abstract

Various simulation studies for wireless body area networks (WBANs) based on the IEEE 802.15.6 standard have recently been carried out. However, most of these studies have applied a simplified model without using any major components specific to IEEE 802.15.6, such as connection-oriented link allocations, inter-WBAN interference mitigation, or a two-hop star topology extension. Thus, such deficiencies can lead to an inaccurate performance analysis. To solve these problems, in this study, we conducted a comprehensive review of the major components of the IEEE 802.15.6 standard and herein present modeling strategies for implementing IEEE 802.15.6 MAC on an NS-3 simulator. In addition, we configured realistic network scenarios for a performance evaluation in terms of throughput, average delay, and power consumption. The simulation results prove that our simulation system provides acceptable levels of performance for various types of medical applications, and can support the latest research topics regarding the dynamic resource allocation, inter-WBAN interference mitigation, and intra-WBAN routing.

“…g ← g + 1. Then, these FSRNs broadcast messages including < id = i, g > to the next-hop nodes synchronously with the broadcasting radius Rb, which is calculated as Equation (13). Each node Nsi that receives the broadcast message and Nsi.tree = 0 responses to the nearest FSRN node Nsj with a message including < id = i >.…”

“…As mentioned above, in recent years, research on UWSNs mainly involves topics like node deployment [ 7 , 8 , 9 , 10 ], node localization [ 11 ], network protocol design [ 3 , 12 ], simulation [ 13 , 14 , 15 ], etc. Specially, the issue of node deployment has attracted attention from lots of scholars and engineers.…”

“…In recent years, acoustic-based UWSNs have been applied in lots of fields such as environment monitoring, military surveillance, data collection, etc [4][5][6]. Research on UWSNs mainly involves node deployment [7][8][9][10], node localization [11], network protocol design [3,12], simulation [13][14][15], etc. Deployment of sensor nodes in 3D UWSNs is a crucial issue, which directly affects the performance of networks.…”
