“…For example, when WBAN is used to monitor a patient's health condition, information have to be delivered instantly. Delays in delivering critical or emergency alarms may be catastrophic [63,65,101,119]. In [110] the researchers stated that it is difficult to ensure acceptable QoS in distributed healthcare systems due to the relative unpredictability of the network environment.…”

Wireless Body Area Network (WBAN) is the most convenient, cost-effective, accurate, and non-invasive technology for e-health monitoring. The performance of WBAN may be disturbed when coexisting with other wireless networks. Accordingly, this paper provides a comprehensive study and in-depth analysis of coexistence issues and interference mitigation solutions in WBAN technologies. A thorough survey of state-of-the art research in WBAN coexistence issues is conducted. The survey classified, discussed, and compared the studies according to the parameters used to analyze the coexistence problem. Solutions suggested by the studies are then classified according to the followed techniques and concomitant shortcomings are identified. Moreover, the coexistence problem in WBAN technologies is mathematically analyzed and formulas are derived for the probability of successful channel access for different wireless technologies with the coexistence of an interfering network. Finally, extensive simulations are conducted using OPNET with several real-life scenarios to evaluate the impact of coexistence interference on different WBAN technologies. In particular, three main WBAN wireless technologies are considered: IEEE 802.15.6, IEEE 802.15.4, and low-power WiFi. The mathematical analysis and the simulation results are discussed and the impact of interfering network on the different wireless technologies is compared and analyzed. The results show that an interfering network (e.g., standard WiFi) has an impact on the performance of WBAN and may disrupt its operation. In addition, using low-power WiFi for WBANs is investigated and proved to be a feasible option compared to other wireless technologies.

For data collection application in wireless sensor networks, it is a hard task to guarantee interference-aware slot assignment in distributed TDMA scheduling algorithm. This paper proposed a new scheduling algorithm based on the collaboration of nodes to resolve the slot collision when nodes try to assign slots to them. The time of network initialization is divided into rounds. The collaboration consisted of three phases: REQ, REPLY, and ACK is used to guarantee the interference-aware slot assignment during each round. The slot information is exchanged when node execute collaboration. We evaluate the performance of our algorithm by using NS2. The results indicate that our algorithm has better packet receive ratio and energy efficiency than existing algorithm.

With the rapid growth of elderly population, ubiquitous healthcare (u-healthcare) service combined with advanced wireless networking technology is gaining popularity. The advance in medical sensor technology has boasted up the u-healthcare market potential. However, the global connectivity with a sufficient level of reliability is still an issue to study for its prototype development. In our previous study (Lee et al. In: Proc BodyNets 2010, Lee et al. in J Commun Netw 13(2):160-166, 2011), the energy efficient packet-level scheduling was studied but the scheduling and management topics in the access stratum, which is the beginning part of end-to-end connection for ubiquitous healthcare service, are still open. In this paper, we study an efficient and adaptive method that can provide u-healthcare user devices with an increased level of access privilege so that the healthcare related user data, which is sometimes delay-critical, can be more favorable admitted to the access stratum. We develop a mathematical formulation for the access control in access stratum domain over the existing 3.9-th generation cellular communication standard, called long term evolution (LTE) and devise an efficient and exact algorithm to solve it. The proposed method has simplicity in implementation and efficiency in operation. In addition, it can improve key performance measures, such as call blocking and call dropping performance.
