This article focuses on identifiers that have direct impact on Quality of Service (QoS)and effect of such identifiers is evaluated through computer simulation using OPNET Modeler 14.5 Wireless Suite. In this paper we have used advanced WiMAX features such as Adaptive Modulation and Coding (AMC), Automatic Repeat Request(ARQ) and Hybrid-ARQ to tune the WiMAX network MAC Layer such that its adaptation improves both capacity and delay (thus optimize the performance). ARQ is treated as higher layer to HARQ. HARQ gives up after maximum retransmissions. HARQ performs fast retransmissions and ARQ takes over in cases HARQ fails after multiple retransmissions. This gives an added layer of protection to data. HARQ is proved to be most suitable (when used with aggressive modulation and coding) for WiMAX due to its hybrid nature as it takes into account both the MAC and link layer. Using ARQ in conjunction with HARQ gives slight improvement in BLER (Block Error Rate) but at the expense of high UL frame utilization.","PeriodicalId":103090,"journal":{"name":"2009 Seventh Annual Communication Networks and Services Research Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127159683","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}

E-health has been widely used as a communication system and information changes to deliver health services to the users through the Internet. However, the Internet imposes threats that will risk the information in transit. Therefore it is important to ensure that the communication is safe and the user’s privacy is protected. This paper extends our previous research results, Multilayer Communication (MLC) approach [1], and introduced mobile agents to MLC in e-health. The cryptographic protocols such as encryption/decryption, digital signature, and hash code are used as protection mechanisms. We focus on how Sender can securely transfer sensitive information to Recipient while still maintaining control over it. Sender keeps the key for decryption at his/her side until the agent needs it. A token is carried by the agent, which is used as a mean to call home platform to obtain the key for decryption processes. The significant of this new mechanism is that it gives Sender control over the transmitted data. Recipient can also avoid burden with the encryption details as long as he/she knows that the message is indeed comes from Recipient.","PeriodicalId":103090,"journal":{"name":"2009 Seventh Annual Communication Networks and Services Research Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123278344","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 quorum system reduces the access cost per operation, to balance the load, and to improve the system scalability. All of these properties make quorum systems particularly attractive for large-scale sensor applications involving data gathering and diffusion tasks. The task of data dissemination with a quorum system is the same as doing a match-making between quorums. But those pseudo quorum systems designed for wired networks fail to address the challenges introduced by sensor networks. In this paper, a novel data dissemination scheme (MM-GSQ) built on top of a new quorum system in wireless sensor network is proposed. The MM-GSQ uses a new quorum system named Spatial Neighbor Proxy Quorum (SNPQ) which is evolved from the pseudo quorum but much smaller. The SNPQ utilizes the geometric properties of the planar graph, e.g., GG or RNG graph, and reduces the quorum access cost greatly as opposed to the traditional pseudo quorum. The MM-GSQ improves energy consumption by reducing message transmissions and collisions, increases the match-making success rate and is easy to be implemented. Theoretical analyses and experimental results indicate that the new quorum system (SNPQ) with related data dissemination algorithm (MM-GSQ) has higher scalability, energy efficiency and match-making success rate than those of the original means. It is especially suitable for data dissemination in large-scale wireless sensor networks (WSNs).","PeriodicalId":103090,"journal":{"name":"2009 Seventh Annual Communication Networks and Services Research Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131565313","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}
