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 we describe a simulation study of the impact of vehicular traffic on the performance of cellular wireless network at microwave carrier frequencies above 3 GHz and up to 15 GHz, where the first and subsequent tiers co-channel interfering cells are active. The uplink information capacity of the cellular wireless network is used for the performance analysis. The simulation results show...
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...
This paper presents an adaptive multiuser receivers scheme for MIMO OFDM over Turbo-Equalization for Single-Carrier Transmission. It involves the joint adaptive minimum mean square error multiuser detection and decoding algorithm with prior information of the channel and interference cancelation in the spatial domain. A partially filtered gradient LMS (Adaptive) algorithm is also applied to improve...
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 cell becomes active as the cell size reduces...
This paper Presents information channel capacity as a fundamental measure of estimating the quality of digital communication channel which is possible with vanishingly small probability of bit error. This work presents that the capacity of a stationary channel with intersymbol interference (ISI) is achievable by both the techniques:1) single carrier modulation with ideal MMSE-DFE receiver and 2)multicarrier...
