In the case of medical applications, the main requirement is to improve the control overhead and to achieve the reliable data transmission. A ZigBee based mobile patient monitoring network model is proposed, and its performance improvement is analysed based on reduced delay and enhanced throughput. We are focusing on the separate and comparative performance evaluation of AODV and DSR routing protocol in a wireless body area network (WBAN). WBAN has numbered of the sensor nodes for collecting the physiological status of patients like ECG, temperature, Heartbeat, etc. Mobile sensor nodes forming an unpredictable topology and link instability that make routing protocols a core issue. In this paper, we considered one wireless network having the hospital care center who monitors mobile patient under AODV and DSR routing protocols, and transmits data to various nodes. Simulation has been performed using OPNET simulation tool, and the results demonstrate that the AODV routing protocol is best suited for medical monitoring system. © 2014 IEEE.

Performance analysis of mobile patient network using AODV and DSR routing algorithms

Spectrum sensing is a primary requirement in cognitive radio systems. In order to improve the spectrum efficiency and facilitate the unlicensed mobile users to use the empty licensed radio frequency band of the electromagnetic spectrum, the spectrum sensing techniques should be more accurate and reliable. In this paper, the disadvantages of basic transmitter detection techniques are discussed, and an innovative, dynamic-double-threshold energy detection scheme is proposed, which overcome the lacunas of existing techniques. Simulation analysis and results show the comparison and performance improvement in terms of detection probability and false alarm probability. © 2014 IEEE.

Comparative performance evaluation of a new dynamic-double-threshold energy detection scheme with basic spectrum sensing techniques

For the sake of improving the overhead occurring due to control operations and to attain the reliable data signaling in the patient monitoring system based on ZigBee, we are focusing on the comparative performance evaluation of different routing algorithm in a wireless body area network (WBAN) using the OPNET simulation tool. WBAN contains the number of wireless mobile nodes forming an unpredictable topology and link instability that make routing a core issue. In this paper a comparative study of three routing algorithms named AODV, DSR, and OLSR has been done with increasing number of wireless nodes in WBAN on account of end to end delay, load, and throughput. Simulation results demonstrate that OLSR routing protocol outperforms among all protocols under an increasing number of node scenario. © 2014 IEEE.
