This second issue of CIT's Volume 26 (June 2018) brings five regular papers from the broad areas of computer networks, embedded systems, Web markup languages, and machine learning.Wireless Body Area Networks (WBAN) are a subclass of sensor networks, finding its use in healthcare applications like monitoring various aspects of a patient's health condition.As the operating frequency band of WBANs overlaps with the 2.4 GHz Industrial Scientific and Medical (ISM) one, interferences are produced, thus causing data losses and quick battery exhaustion.Already known solutions to these problems are costly, complex and of lacking quality.In their paper, titled Adaptive Parameters Adjustment in WBAN based IEEE 802.15.4 Protocol to Mitigate Wi-Fi Interferences, Essafi Sarra and Tahar Ezzedine thus propose an alternative method for adaptively adjusting specific parameters (value of packet size, CCA duration and backoff timeslot) in the Medium Access Control (MAC) layer, which is simple, low-cost and dynamic.They provide the related theoretical analysis along with its effectiveness through a set of simulations using the well-known discrete event simulator OMNeT++.The results obtained prove both the reduction of the effects of interferences in WBANs as well as sustainment of quality of service.
