A technique is developed for ad hoc on-demand routing protocol. The protocol is based on the conventional on-demand ad hoc routing protocols with the addition of power model. The algorithm design and development is aimed to incorporate the transmitted power consumption function in such a manner that mobile nodes are able to evaluate their power status to decide if they are fit for packet forwarding...
The central challenge in the design of ad-hoc wireless networks is the development of a dynamic routing protocol that efficiently finds routes between mobile nodes. Several network routing protocols such as Dynamic Source Routing (DSR), Ad Hoc On-demand Distance Vector (AODV) and Destination Sequence Distance Vector (DSDV) have been proposed to facilitate communication in a dynamically changing network...
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 Source Routing Protocol in Mobile Wireless...
In this paper, we describe a simulation study of the impact of topology control and traffic models on the performance of Mobile Ad Hoc Wireless Network routing protocol in a dynamic changing environment. Simulation results shows that Constant Bit Rate (CBR) outperformed Transmission Control Protocol (TCP) in all metrics chosen, except for TCP which was able to handle packet delivery in large topologies...
In this paper, the mathematical analysis supported by computer simulation is used to find the information capacity of adaptive MIMO OFDM in digital communication systems. Result shows that in additive white Gaussian noise (AWGN) channel, the capacity performance of Least mean square (LMS) is poor while the recursive least square (RLS) shows an increase in capacity as the SNR increases. The joint channel...
In this paper, we describe a simulation performance of Vehicular Ad hoc network on different traffic models in a dynamic changing environment. The simulation results showed that as delay and jitter increases, the throughput of receiving bits decreases, the nodes stabilizes and the delay tends to drop at interval but packets do drop as the packet size increases.
In this paper, we describe a simulation study of the impact of wireless channel on Dynamic Source Routing (DSR) protocol performance at microwave carrier frequencies above 2 GHz. Simulation results show that at microwave carrier frequencies above 2 GHz, when the two-slope path loss model is used for channel modelling, the breakpoint distance affect the end-to-end throughput of the DSR protocol in...
The science of computer networking and the proliferation of mobile devices enable the capabilities of communicating with each other even in areas with no pre-existing communication infrastructure. Traffic and mobility models play an important role in evaluating the performance of these networks, despite criticism and assumption from various researches on TCP's weaknesses on MANET. A simulation was...
