Wireless Body Area Network (WBAN) is extensively being used for ubiquitous health care monitoring. Coexisting multiple WBANs could possibly suffer from high interference and thus an appropriate scheduling scheme is desirable to improve network throughput for interfering nodes. The received Signal to Interference and Noise Ratio (SINR) from the sensors in the overlapped region of two or more WBANs which use the same transmitting frequency drops. This decrease is an indicator of inter-WBAN interference. Hence, we propose a scheduling algorithm which assigns the node with minimum SINR to first available transmission slot and so on. Thus, the nodes which suffer maximum interference are given higher priority to transmit in the revised Time division multiple access (TDMA) schedules. The local coordinator of each WBAN exchange messages with the interfering WBAN's coordinator and then tries to suppress interference by creating a new TDMA schedule for interfering nodes. Results obtained using simulations are encouraging as they indicate that minimum weight match scheduling can improve the packet drop rate and thus enhance the network performance.

“…WBANs are similar to MANETs in terms of the moving topology with groupbased movement rather than node-based movement [6]. However, WBANs have more strict energy constraints in terms of transmit power compared to traditional sensor and Ad Hoc networks as node replacements particularly for implant nodes can be quite uncomfortable and might require surgery in some scenarios.…”

“…Therefore, it is crucial for WBANs to have a longer network lifetime to avoid constant recharging and replacement of nodes attached to a person. Additionally, a WBAN has more frequent topology changes and a higher moving speed, whilst a WSN has static or low mobility scenarios [6]. Due to the aforementioned issues and specific WBANs challenges, the routing protocols designed for MANETs and WSNs are not applicable to WBANs [7].…”

Recent developments in wireless communications, MicroElectroMechanical Systems (MEMS) technology and integrated circuits have enabled low-power, intelligent, miniaturized, invasive/non-invasive micro sensor nodes strategically placed in or around the human body which forms Wireless Body Area Networks (WBANS) to be used in various applications including remote health monitoring. Due to inherent issues and specific challenges, routing protocols designed for Mobile Adhoc Networks (MANETs) and Wireless Sensor Networks (WSNs) are not applicable to WBANs. QoS-Aware Routing protocols mainly provide a modular approach by presenting separate modules for different QoS metrics that operate in coordination with each other. These approaches aim at providing higher reliability, lower end-to-end delay and higher packet delivery ratio. In this paper various issues and challenges in pursuit of effective QoS-Aware routing are identified and detailed literature survey of the various existing QoS-aware routing protocols, their strengths and weaknesses are discussed.

“…Unfortunately, interference mitigation schemes proposed for other networks, such as traditional wireless sensor networks (WSNs), cannot be deployed in WBANs because of the following differences: A WBAN mainly has more frequent topology changes and a higher moving speed whilst a WSN has static or low mobility scenarios; WBANs are different to mobile ad hoc networks (MANETs) in terms of their moving topology with group-based movement rather than node-based movement as in MANETs. Thus, due to the group-based movement and high mobility nature of WBANs they are not similar to WSNs or MANETs which implies interference mitigation approaches in both WSNs and MANETs cannot be used for WBANs [7]. In addition, due to the limitations of WBANs in terms of cost, size and energy consumption, the function of each sensor node needs to be very simple.…”

This paper presents an adaptive interference mitigation scheme for multiple coexisting wireless body area networks (WBANs) based on social interaction. The proposed scheme considers the mobility of nodes within each WBAN as well as the relative movement of WBANs with respect to each other. With respect to this mobile scenario traffic load, signal strength and the density of sensors in a WBAN are incorporated to optimize transmission time with synchronous and parallel transmissions to significantly reduce the radio interference and energy consumption of nodes. This approach leads to higher packet delivery ratio (PDR) and longer network lifetime even with nodes dynamically moving into and out of each others interference region. We make channel assignment more energyefficient and further reduce power consumption using transmit power control with simple channel prediction. Simulation results show that our approach maintains optimum spatial reuse with a range of channel dynamics within and between coexisting BANs. This protocol based on social interaction is shown to mitigate interference and minimize power consumption, and increase the spatial reuse and PDR of each WBAN, while increasing network lifetime. In the context of the adaptive interference mitigation scheme proposed, this paper also reviews the state of art in literature on mobility, MAC layer and power control solutions for WBANs, as well as providing a summary of interference mitigation schemes previously applied in WBANs.
