On PHY and MAC Performance in Body Sensor Networks
This paper presents an empirical investigation on the performance of body implant communication using radio frequency (RF) technology. In body implant communication, the electrical properties of the body influence the signal propagation in several ways. We use a Perspex body model (30 cm diameter, 80 cm height and 0.5 cm thickness) filled with a liquid that mimics the electrical properties of t...
متن کاملmac protocols in underwater wireless sensor networks: issues and simulations
underwater acoustic wireless sensor network (uawsn) use acoustic signalsto transmit data. acoustic signals in underwater environment have high bit errorrate, long propagation delay and limited bandwidth. another constraint in uwasnis energy. due to these constraints, design of energy and bandwidth efficient andpropagation delay aware mac protocol is a great challenge in uwasn.underwater sensor ...
متن کاملPHY and MAC Layer Security in 802.11 Networks
IEEE 802.11-based wireless networks are being deployed in large numbers in home, business, and public environments but also in critical environments like hospitals or production plants where reliance on their availability is crucial. For example, Cisco reports that a 802.11n network is being deployed in a German university clinic to monitor vital parameters of patients as they are moved between...
متن کاملTowards Power Efficient MAC Protocol for In-Body and On-Body Sensor Networks
This paper presents an empirical discussion on the design and implementation of a power-efficient Medium Access Control (MAC) protocol for in-body and on-body sensor networks. We analyze the performance of a beacon-enabled IEEE 802.15.4, PB-TDMA, and S-MAC protocols for on-body sensor networks. We further present a Traffic Based Wakeup Mechanism that utilizes the traffic patterns of the BAN Nod...
متن کاملD-MAC: A Dynamic MAC Algorithm for the Body Area Sensor Networks Based on IEEE 802.15.4
Wireless Body Area Network (WBAN) is a wireless sensor technology used to connect small nodes with sensing abilities to collect necessary information. IEEE 802.15.4 is commonly adopted for WBAN because of its low duty cycle and low power operation. WBAN data is communicated in a superframe structure defined by IEEE 802.15.4 beacon enabled mode. Superframe structure predominantly based on beacon...
