Data Dissemination Strategies for Emerging Wireless Body-to-Body Networks based Internet of Humans
With the recent advent of Internet of Humans (IoH), wireless body-to-body
networks (WBBNs) are emerging as the fundamental part of this new paradigm. In
particular with reference to newly emerging applications, the research trends
on data routing and dissemination strategies have gained a great interest in
WBBN. In this paper, we present the performance evaluation of the clustered and
distributed data dissemination approaches in tactical WBBN. We used a realistic
radio-link and biomechanical mobility model for on-body motions, and group
mobility model for WBBN to effectively realize rescue and emergency management
application scenario. In this regard, we are using the newly proposed IEEE
802.15.6 standard targeted for body area networks. Extensive (IEEE 802.15.6
standard compliance) network level, packet oriented simulations are conducted
in WSNet simulator. During the simulations, various payloads, frequencies
(narrow-band) and modulation techniques are exploited. We based our performance
evaluation on relevant metrics according to the operational requirements for
tactical networks such as packet reception ratio, latency, energy consumption
and hop count. The results showed a trade-offs between clustered-based and
distributed-based dissemination approaches. With regards to packet delay,
distributed approach provided the best performance. However, in terms of
average packet reception ratio (PRR), clustered-based approach achieves up to
97% reception and remained the best strategy. Whereas, the results of the hop
count and energy consumption are almost comparable in both schemes.Comment: WiMob, Oct 2015, Abu Dhabi, United Arab Emirate
