Book excerpt: Research Paper (postgraduate) from the year 2014 in the subject Computer Science - Internet, New Technologies, , language: English, abstract: Ad-hoc network is a concept in computer communications, which means that users wanting to communicate with each other from a temporary network, without any form of centralized administration. Each node participating in the network acts both as host and router and must therefore be willing to forward packets for other nodes. For this purpose, a routing protocol is needed. Routing protocols in MANET such as OLSR-INRIA, DSR and ZRP finds out the path between a given sources destination node pair without considering the reliability of the links in the selected path. Some links in MANET are unreliable due to interference from transmissions from adjacent links, ambient noise system noise, jamming signals from intruder nodes all of which results in low throughput, packet delivery ratio, high jitter and end-to-end delay. In our work, we use Signal-to-Noise Ratio (SNR) as a measure of the link reliability. We propose modified secure version of the of three protocols namely OLSR-INRIA, DSR & ZRP coined as SOLSR-INRIA , SDSR, & SZRP which takes into account the link SNR value as a measure of link reliability in addition to the other parameters as in the original method in the route discovery phase. QualNet network simulator have been extensively used to evaluate the performance of our modified secure routing protocol over two different network scenarios consisting of 52 and 72 mobile nodes respectively considering random waypoint (RWP) mobility model. The results indicate high throughput, high packet delivery ratio and low jitter and end-to-end delay in comparison to the original protocols which do not account for wireless links reliability.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation endeavors to contribute enhancements in goodputsof the IEEE 802.11-based Wireless Multi-hop Networks (WMhNs).By performing exhaustive simulations, for the deep analysis and detailed assessment of both reactive (AODV, DSR, DYMO) and proactive (DSDV, FSR, OLSR) protocols for varying mobilities, speeds, network loads and scalabilities, it is observed that a routing link metric is a significant component of a routing protocol. In addition to finding all available paths, the fastest end-to-end route is selected by a link metric for the routing protocol. This study aims the quality routing. In the class of quality link metrics, Expected Transmission Count (ETX) is extensively used. Thus, the most recently proposed ETX-based metrics have been analyzed. Though, newly developed metrics over perform ETX but still they can be improved. By profound analysis and particularized comparison of routing protocols depending upon their classes (reactive and proactive) and ETX-based metrics, we come to realize that users always demand proficient networks. In fact, WMhNs are facing several troubles which they expect to be resolved by the routing protocol operating them. Consequently, the protocol depends upon the link metric for providing quality paths. So, we identify and analyze the requirements to design a new routing link metric for WMhNs. Because, considering these requirements, when a link metric is proposed, then : firstly, both the design and implementation of the link metric with a routing protocol become easy. Secondly, the underlying network issues can easily be tackled. Thirdly, an appreciable performance of the network is guaranteed. Keeping in view the issues of WMhNs, increasing demands of users and capabilities of routing protocols, we propose and implement a new quality link metric, Interference and Bandwidth Adjusted ETX (IBETX). As, MAC layer affects the link performance and consequently the route quality, the metric therefore, tackles the issue by achieving twofold MAC-awareness. Firstly, interference is calculated using cross-layered approach by sending probes to MAC layer. Secondly, the nominal bit rate information is provided to all nodes in the same contention domain by considering the bandwidth sharing mechanism of 802.11. Like ETX, our metric also calculates link delivery ratios that directly affect throughput and selects those routes that bypass dense regions in the network. Simulation results by NS-2 show that IBETX gives 19% higher through put than ETX and 10% higher than Expected Throughput (ETP). Our metric also succeeds to reduce average end-to-end delay up to 16% less than Expected Link Performance (ELP) and 24% less than ETX.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is very difficult to pursue research over real-time networks at the meantime implementation of such components are costly. Network simulators reduce this task in real time and accomplish this task with less time and cost. There are many network simulators available in the market like Ns2, Ns3, OMNET++, OPNET, NetSim, QualNet, REAL, J-Sim, SWAN, Jist, and GloMoSiM. Generally, Network simulators are used to analyze network performance and measurement metrics. It has been observed that several standing authors did not compare routing protocols with network simulators in general. This paper presents a comparison of results of NS3 and OMNET++ i. e. open source simulators for analyzing Mobile Ad hoc routing protocols by means of Packet Delivery Ratio, Routing Overhead, Throughput, Average end to end delay and Path Optimality. Further, it was analyzed that which one open source simulator is most fit for research purposes. This research presented proactive, reactive and hybrid routing protocols and compared with both network simulators. Experimental results clearly differentiate the performance differences of selected simulators and help in the selection process for network simulators by salient stakeholders.
