On the other hand, Orthogonal Frequency Division Multiplexing (OFDM) technique has emerged as a very popular multi-carrier modulation technique to enhance the data rate of future broadband wireless communication systems. Applying these technologies with a wireless relay network where multiple user pairs conduct bidirectional communications via multiple relays based on OFDM transmission. The joint optimization of channel and relay assignment, including subcarrier pairing, subcarrier allocation as well as relay selection, for total throughput maximization is formulated as a combinatorial optimization problem. Using a graph theoretical approach, we solve the problem optimally in polynomial time by transforming it into a maximum weighted bipartite matching (MWBM) problem. Simulation studies are carried out to evaluate the network total throughput versus transmit power per node and the number of relay nodes.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132948121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These attacks are due to the participation of malicious nodes in the network. Routing protocols are a common target of these nodes. A variety of secure routing protocols have been proposed, that make routes secure using cryptographic algorithms. However, in doing so, these protocols need a number of rudiments in both the network establishment and operation phases. In contrast, by observing the honesty in participation by other nodes, trust-based routing protocols discover trusted rather than secure routes in the network. These protocols thus allow rapid deployment along with a vigorously adaptive operation, which conforms to the present network situation. In this paper, we conduct the performance evaluation of four reactive routing protocols in a network with varying speed, network dimension and number of malicious nodes. With the help of comprehensive simulations, we demonstrate that the performance of these protocols is analyzed using Packet delivery ratio, Throughput, End-to-End Delay and Routing Load under similar attacks, traffic, and mobility conditions. However, each routing protocol has its own peculiar advantage making it suitable for application in a particular unplanned environment.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128450107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These electronic devices are nothing but the nodes of the Mobile Ad hoc Network (MANET). Each node can move from one place to other during communication and this mobility is having its effect on performance of the network. Mobility changes when speed of the node and pause time with which it moves changes. Change in mobility causes break of link with neighboring nodes as a result of which the performance of a network may be reduced. A number of packets are dropped at different layers of the network. This paper describes the analysis of change in performance due to change in mobility and transmission power. The parameters describing the reason of variation in performance are (1) number of link breaks and (2) number of packet delivered. (3)End to end delay. The simulator we have used in our work for the calculation of performance matrices is GLOMOSIM. The performance comparison has also made between two types of on demand routing protocols AODV and DSR.","PeriodicalId":149158,"journal":{"name":"2014 Eleventh International Conference on Wireless and Optical Communications Networks (WOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122640996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
