In this scheme, the number and positions of the virtual beacons is determined based on equilateral triple optimal coverage, so sufficient localization information can be obtained for each unknown node.

In order to further improve location accuracy, we propose the optimal filtering method to select the optimal set of virtual beacon points for node localization.

However, how to extract some characteristics from a transmitter and how to use the relation between different characters to identify the transmitters is very difficult task in the radio transmitter identification. In order to overcome the deficiencies based on single character in the traditional method which has a low correct recognition rate, a novel classification method based on multi-feature joint detection for radio transmitter identification is proposed in this paper.

Security processors for portable electronic devices should occupy small area, consume low power, handle several cryptography algorithms, and provide acceptable performance.

The new architecture can reduce the area and power consumption of security chip, and improve universality, flexibility and security of the whole system.

Secondly, a min-max optimal programming model is presented to describe the routing strategy.

By solving this model, the number of transmitted packets of each relay node can be estimated precisely and it is the foundation of maximize sensor network lifetime.

OVSF codes are getting popular due to his efficiency and flexibility to allocate variable bite rates for different bandwidth requirement of applications. A core design issue of OVSF code allocation schemes is to utilize the codes efficiently such that more data can be forwarded to subscribers and as soon as possible. In literal, there are different OVSF code-allocation schemes have been proposed and evaluated. In this paper, we proposed an alternate OVSF code allocation scheme for single and dedicate code allocation in WCDMA systems. The code allocation scheme consists of two parts: rate allocation and code assignment. First, we decide the rate for each active connection according to user profiles of the connection and available data in data buffer. Second, we assign OVSF code for each active connection according to the results of the rate allocation in the first stage. We compared our propose scheme with other schemes proposed in recent years. Results showed that our scheme outperforms the others, regarding data throughput and delay.","PeriodicalId":296445,"journal":{"name":"2010 International Conference on Communications and Mobile Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130926695","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}
