MANET is a multi-hop, self configuring and autonomous network that can use intermediate mobile nodes as a router and transmit data between mobile devices. A quadrant based intelligent energy controlled multicast algorithm for MANET identified during earlier research is the basis for the algorithm presented in this paper. Simulation results and comparison with other MANET routing algorithms highlighted that the algorithm is energy efficient and reliable but relatively slow for data transmission. An improved MANET routing algorithm is proposed in this paper which eliminates the data transmission delay limitation and increases the number of delivered packets. The new algorithm is called 4-N Intelligent Routing Algorithm as it selects a subset of 4 intermediate nodes located in the direction of the destination node and uses an intelligent energy matrix to distribute the load among the subset of nodes. Simulations were carried out of the proposed MANET algorithm using Opnet Modeler v16. Comparison with other MANET routing algorithms showed that the proposed algorithm successfully delivers more packets, reduces end to end delay and utilizes comparable energy for data transmission.","PeriodicalId":210916,"journal":{"name":"2011 Australasian Telecommunication Networks and Applications Conference (ATNAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124982913","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}

Emerging in-network aggregation techniques are increasingly being sought to overcome this constraint and to save precious energy. In our previously proposed method, entitled “Data Aggregation for Mobile Object Using Rate-Distortion” (DAMORD), we introduced a mathematical model for data aggregation for the moving object and exploited spatial correlation in sensed data. However, due to the complex computation arising from movement of the object, a more practical version of the original algorithm, DAMORD-SC, is presented here which significantly reduces the computation overhead using Static Clustering (SC) mechanism. In this innovative approach, predefined clusters are split into grids and pre-calculated correlation matrices are used to perform data aggregation. With the new mechanism to assess the accuracy of the method, proper grid size for clusters is obtained under different conditions with consideration to energy consumption and data accuracy. Detailed energy consumption measurements are made using the precise energy model for communication operation as well as sim-Panalyser for computation energy. Simulation results in NS-2 demonstrate that this enhanced scheme achieves substantial energy saving under a high correlation setup within the user-defined distortion rate.","PeriodicalId":210916,"journal":{"name":"2011 Australasian Telecommunication Networks and Applications Conference (ATNAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122096887","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}

We deduce the rate and quality model parameters for video characterization of the SVC extension of the H.264/AVC and propose an optimization framework for sum quality maximization of the transmitted video streams in unicast and multicast 4G scenarios. We derive the closed form solution for optimal quantizer selection towards net video quality maximization subject to rate constraints of the unicast/ multicast users, taking into account the different modulation and coding rates of the multicast groups in the 4G wireless system. This in turn yields the optimal OFDMA time/frequency resource allocation for video multiplexing. In the simulation results section, we specialize our proposed algorithm in the context of WiMAX based 4G video transmission and demonstrate that our algorithm provides significant improvement in video quality over the content agnostic non-scalable equal symbol rate allocation scheme for unicast and multicast scenarios.","PeriodicalId":210916,"journal":{"name":"2011 Australasian Telecommunication Networks and Applications Conference (ATNAC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127674334","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}
