The performance of wireless body area networks (WBANs) may be degraded due to co-channel interference, i.e., when sensors of different coexisting WBANs transmit at the same time-slots using the same channel. In this paper, we exploit the 16 channels available in the 2.4 GHz unlicensed international band of ZIGBEE, and propose a distributed scheme that opts to avoid interference through channel to...
This work addresses problems related to interference mitigation in a single wireless body area network (WBAN). In this paper, We propose a distributed Combined carrier sense multiple access with collision avoidance (CSMA/CA) with Flexible time division multiple access (TDMA) scheme for Interference Mitigation in relay-assisted intra-WBAN, namely, CFTIM. In CFTIM scheme, non interfering sources (transmitters)...
In this paper, we consider a dynamic system composed of several Wireless Body Area Networks (WBANs) interacting with the surrounding environment, forming Body-to-Body Networks (BBNs). In this dynamic BBN system, we analyze the joint mutual and cross-technology interference problem due to the utilization of a limited number of channels by different transmission technologies (i.e., ZigBee and WiFi)...
This paper considers the problem of intra-interference in a Wireless Body Area Network (WBAN). The problem arises mainly because each bio-sensor collects different parameters with different data rate and alternation. Another source of interference is related to normal patient movement. Proposals in the literature usually assume that the interference can be handled using time multiplexing or by listening...
Wireless body area network (WBAN) witness an upward interest in several domain. Mainly, the medical domain takes advantages from the health service facility, the high flexibility and the mobility. However, interferences from coexisting wireless networks may lose critical informations and greatly affect on network reliability. In this paper, we are conducting to improve coexistence between WBAN based...
In this paper, we propose a new framework for online detection and isolation of faulty measurements reported by medical wireless sensors. In our proposed framework, each sensor applies the non-seasonal Holt-Winter algorithm to detect any deviation in the time series associated with its measurements, and it will only transmit the detected abnormal values to the portable collection device (smart phone),...
In recent years, Body-to-Body Networks (BBNs) have gained momentum as a means to monitor people behavior and simplify their interaction with the surrounding environment; thus representing a key element of the Internet of Things (IoT) networking paradigm. Within BBNs, several transmission technologies sharing the same unlicensed band (namely the ISM band) coexist, increasing dramatically the level...
