In uplink transmissions of these systems, independent and autonomous mobile users may act selfishly in order to get a higher share of available resources, which is encountered by a pricing mechanism that penalizes the interference they create. Specifically, the mobile users strategically decide on their power levels to minimize their cost which is the difference between their utilities based on Shannon capacity and payments. The base station acts as a mechanism designer to ensure that certain global objectives are satisfied when allocating resources. In this paper, we consider two such objectives: one is sum of user utility maximization and the other one is operator revenue maximization based on the prices charged to users, which coincidentally acts as the coupling factor between user and designer optimization problems. We analyze first the single carrier case as a starting point, which we immediately extend to multi carriers. We next formulate the operator revenue maximization problem using the same framework. Numerical simulations illustrate the mechanism developed and show the convergence of power and price levels of the users.","PeriodicalId":119856,"journal":{"name":"2011 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116889827","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 802.15.4g specifies three alternative physical (PHY) layer designs, thus having multiple homogeneous systems within the SUN system. The three homogeneous systems are allocated across shared frequency bands dependent on different regulatory domains. Besides coexistence for homogeneous systems, the SUN system is also sharing several frequency bands with multiple heterogeneous systems across various other 802 standards. Understanding the details of these coexisting dissimilar systems is an essential step to creating a harmonious radio environment. Therefore, this paper provides the outline of the coexisting homogeneous and heterogeneous systems, as well as the corresponding frequency bands that are allocated in different regulatory domains. Secondly, the overview on the coexistence mechanisms applicable in the 802.15.4g system is presented. Thirdly, coexistence analysis is performed on two dissimilar systems, where the performance degradation of a victim system is evaluated in the presence of an interferer. As a collective result, it is shown that with victim-interferer separation of beyond approximately 30m, dissimilar systems are able to coexist even without higher layer coexistence mechanisms.","PeriodicalId":119856,"journal":{"name":"2011 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133666155","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}
