Wireless body area networks (WBANs) facilitate efficient and cost-effective e-health care and well-being applications. The WBAN has unique challenges and features compared to other wireless sensor networks. In addition to battery power consumption, the vulnerability and the unpredicted channel behaviour of the MAC layer make channel access a serious problem. Time Division Multiple Access (TDMA) Medium...
Wireless Body Area Network (WBAN) has been a potential avenue for future digitized healthcare systems. WBAN has unique challenges and features compared to other wireless sensor networks. In addition to battery power consumption, the vulnerability and the unpredicted channel behaviour make channel access a serious problem. Time Division Multiple Access (TDMA) Medium Access Control (MAC) protocols can...
In Wireless Sensor Networks (WSNs), energy conservation is one of the main concerns challenging the cutting-edge standards and protocols. Most existing studies focus on the design of WSN energy efficient algorithms and standards. The standard IEEE 802.15.4 has emerged for WSNs in which the legacy operations are based on the principle that the power-operated battery is ideal and linear. However, the...
Many challenges confront the wide deployment of wireless communications such as signal attenuation, fading and shadowing. Those problems are solved by adopting cooperative communication technique that mimics MIMO technology (virtual MIMO). Following MIMO, nodes act as if they have multiple antennas but actually they are not. While cooperative networks have solved many communication problems through...
