“…While receiving the beacon signal, the sensor nodes obtain the channel for transmitting data packets to the coordinator. In Reference [ 11 ], the coordinators use channel hopping techniques to allocate the transmission of sensor nodes into a specific channel and timeslot. Collisions with other neighboring WBANs as well as energy consumption are minimized.…”

“…The high-load traffic at the sensor nodes may cause collisions in intra-WBAN transmission, resulting in the degradation of network throughput. Currently, to cope with the need for higher network throughput, multi-channel MAC protocols are considered to increase the network throughput in various wireless networks such as wireless sensor networks, ad hoc networks, cognitive radio networks, and WBANs [ 8 , 9 , 10 , 11 , 12 ].…”

Herein, we propose a hybrid multi-channel medium access control (HM-MAC) protocol for wireless body area networks (WBANs) that mitigates inter-WBAN interference significantly. In HM-MAC, a superframe consists of a random access phase and a scheduled access phase. That is, a carrier sensing multiple access with collision avoidance (CSMA/CA) phase and a time division multiple access (TDMA) phase are included in a superframe. The random access phase allows higher-priority users to transmit data packets with low latency and high reliability. The retransmission of data packets is also performed in the random access phase. The periodic data are transmitted in the scheduled phase, resulting in no contention and high reliability. A channel selection algorithm is also proposed to avoid collision between neighboring WBANs. The HM-MAC protocol allows multiple transmissions simultaneously on different channels, resulting in high throughput and low collision. The sensor nodes update idle channels by listening to the beacon signal; consequently, the sensor nodes can change the working channel to reduce inter-WBAN interference. According to our simulation results, HM-MAC achieves a higher packet delivery ratio and higher throughput with lower energy consumption than the conventional scheme in multi-WBAN scenarios. HM-MAC also causes lower end-to-end delays for higher-priority users.

“…The originality of this work resides in the use of traffic history to guide the channel allocation in a distributed manner. Ali et al, [5] proposed a distributed scheme that avoids interference amongst coexisting WBANs through predictable channel hopping. Based on the Latin rectangle of the individual WBAN, each sensor is allocated a backup time-slot and a channel to use if it experiences interference such that collisions among different transmissions of coexisting WBANs are minimized.…”

Abstract-Recent advances in microelectronics have enabled the realization of Wireless Body Area Networks (WBANs). However, the massive growth in wireless devices and the push for interconnecting these devices to form an Internet of Things (IoT) can be challenging for WBANs; hence robust communication is necessary through careful medium access arbitration. In this paper, we propose a new protocol to enable WBAN operation within an IoT. Basically, we leverage the emerging Bluetooth Low Energy technology (BLE) and promote the integration of a BLE transceiver and a Cognitive Radio module (CR) within the WBAN coordinator. Accordingly, a BLE informs WBANs through announcements about the frequency channels that are being used in their vicinity. To mitigate interference, the superframe's active period is extended to involve not only a Time Division Multiple Access (TDMA) frame, but also a Flexible Channel Selection (FCS) and a Flexible Backup TDMA (FBTDMA) frames. The WBAN sensors that experience interference on the default channel within the TDMA frame will eventually switch to another Interference Mitigation Channel (IMC). With the help of CR, an IMC is selected for a WBAN and each interfering sensor will be allocated a time-slot within the (FBTDMA) frame to retransmit using such IMC.

“…In LQE, there are two types of estimators: (a) hardwarebased estimators that are based on using signal strength of a received packet that is obtained directly from radio transceiver, and (b) software-based estimators that are collected via the persistent tracking of messages losses. The main advantage of this type of estimators is that they do not depend on specific hardware and correlate directly with the application layer [10], [11]. The link quality estimation process consists of three steps: 1) Link Monitoring: three kinds of link monitoring can be used: active link monitoring, passive link monitoring, and hybrid link monitoring.…”

Information-Centric Networking (ICN) is a new communication paradigm that replaces the host addresses by the name of content; Named Data Networking (NDN) is a promising ICN architecture that has attracted research attention in recent years. NDN is a receiver-driven architecture implements pullbased communication in the form of one-interest-one-data. This model poses different challenges, especially from the transport layer perspective. In contact to IP-based networks where the congestion is handled in an end-to-end manner, NDN cannot apply the same concept, while most of the existing solutions are based on hop-by-hop connection. In this paper, we present a new congestion control mechanism for NDN based on link quality estimation. We focus our efforts to provide fast data transmission, decrease packet dropping rate, and maximize the link utilization. The simulation results show that our solution outperforms the NDN schemes in terms of throughput and drop packets.
