A technique is proposed to evaluate the effect of ambient noise and path loss have on received signal strength of mobile node in a mobile ad hoc network environment using optimized network (OPNET) simulator while comparing the performance of Ad-Hoc on demand distance vector (AODV) and dynamic source routing (DSR) protocols. Numerical and simulation results(More)
BACKGROUND Continuing the administration of magnesium sulphate for 24 hours after the last fit in patients with eclampsia is at best empirical. The challenge of such a regimen is enormous in low-resource countries. The objective of this study was to assess the effectiveness of an ultra-short regimen of magnesium sulphate in eclamptics. FINDINGS This was a(More)
—In this paper, mathematical analysis supported by computer simulation is used to study cellular system information capacity change due to propagation loss and system parameters (such as path loss exponent, shadowing and antenna height) at microwave carrier frequencies greater than 2 GHz and smaller cell size radius. An improved co-channel interference(More)
—In this paper, mathematical analysis supported by computer simulation is used to investigate the impact of both system and propagation loss parameters on the performance of cellular wireless network operating at microwave carrier frequencies greater than 2 GHz, where multiple tier of co-channel interfering cells are considered to be active. The two-slope(More)
In this paper, results of mathematical analysis supported by simulation are used to investigate the impact of propagation loss on the performance and information capacity of cellular wireless network at higher microwave carrier frequencies (beyond 2 GHz). At higher microwave carrier frequencies co-channel interfering cells beyond the first six co-channel(More)
— In this paper, an Adaptive Receiver Power Routing (ARPR) protocol technique for Mobile Ad Hoc wireless network is proposed. The adaptive receiver power routing (ARPR) protocol evaluates the effect of environment, and signal path loss on a mobile ad hoc wireless network quality of service (QoS) and throughput performance. The proposed technique is(More)
In this paper, we describe a computer simulation study of the sensitivity of Dynamic Source Routing (DSR) protocol performance to wireless channel at microwave carrier frequencies greater than 2 GHz. Performance simulation results show that at microwave carrier frequencies greater than 2 GHz, the break point distance effect the performance of the Dynamic(More)
