The solution for reducing the verbosity and the performance cost of XML has been the use of the alternative encoding schemes, other than pure text. The processing of the XML using computing resources sparingly is even more important in embedded, and otherwise restricted environments, when the services of the enterprise domain are extended to the mobile wireless domain. This paper presents and studies the empirical results of computational resource consumption by benchmarking of an implementation of the Message Oriented Middleware, MOM. This MOM solution defines and implements a service and application level messaging protocol and appropriate middleware. The benchmarked MOM implementation provides XML and two alternative binary encoding presentations for the messages, a proprietary binary encoding and an XBIS encoding. The message encoding schemes are compared by considering message compression, protocol overhead and measured computing resource usage. The measured computing resource usage includes CPU processing load and memory consumption. The results show the advantage of the binary encoding over the traditional XML, in most cases. However, the study also showed how XML is preferred for the lengthy messages that have a higher share of payload data.","PeriodicalId":308667,"journal":{"name":"2008 The Fourth International Conference on Wireless and Mobile Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685256","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}

As a consequence of providing Internet access to many clients over such a network, throughput is affected by the number of hops that a client is from its backhaul and how traffic load distributing. These spatial bias and load- balancing problems are formulated as a mixed-integer nonlinear programming problem that take into consideration the multi-hop delay, both in terms of least-hop and load-balanced routing, and in terms of link capacity constraints in mesh structures. In this paper, we proposed distributed resource allocation scheme and load-balanced routing algorithms combining with Lagrangean Relaxation approach that minimize the maximum multi-hop delay at the MAC layer and network layer, algorithms that achieve load-balanced on each backhaul and each branch of the backhaul with orthogonal channels. Our experiment results demonstrate that the algorithms achieve near-minimum multi- hop delay and outperform other resource allocation schemes and routing algorithms.","PeriodicalId":308667,"journal":{"name":"2008 The Fourth International Conference on Wireless and Mobile Communications","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975404","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}

The CI-OFDM system can show the advantage of PAPR (peak to average power ratio) reduction and frequency diversity gains without any loss in the communication throughput. In this paper, focusing on the two Tx (transmit) / one Rx (receive) antennas and two Tx / two Rx antennas configuration in the MIMO (multiple input multiple output) antenna array systems, we like to design and evaluate the performance of this MIMO CI-OFDM system. SFBC (space frequency block coding) coding is used for the MIMO CI-OFDM system. For CI-OFDM realization, digital implemented CI-OFDM structure is used in which CI code spreading operation and carrier allocation are separately processed by simple IFFT type operation. From the simulation results, it is shown that MIMO SFBC CI-OFDM reduces PAPR significantly compared with the conventional MIMO SFBC-OFDM system. The out-of band re-growth of signal spectrum in MIMO SFBC CI-OFDM system is much smaller than MIMO SFBC OFDM. In the NBI (narrow band interference) channel MIMO SFBC CI-OFDM system achieves considerable BER improvement.","PeriodicalId":308667,"journal":{"name":"2008 The Fourth International Conference on Wireless and Mobile Communications","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126283649","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}
