With increasing amount of network traffic, the failure of network components such as distribution fiber link failure may lead to unpredictable service outages. The network survivability through protection and restoration has become a critical requirement. Thus, in this paper, we explore the protection mechanism for small cells by integrating WiFi and rerouting of data traffic over WiFi to offer some restoration of backhaul capacity. Using this architecture, we propose a novel method to optimize the deployment and maximize the coverage of survivable FiWi access network, with appropriate constraints from connectivity, survivability, capacity and delay perspectives. Our simulation results show the successful reconfiguration of survivable FiWi access networks with integrated small cell and WiFi under different simulated network failure scenarios and we demonstrate feasibility of the proposed optimization method.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123975679","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}

However, small cells usually transmit with a weaker power compared to macro-cells, this fact causes a serious interference problem for these former. Range Expansion technique is among the solutions proposed to overcome this problem. The idea is to bias the received signal power from pico-cells in an advantage manner so that we have more UEs offloaded from macro-cell than the real case. Many solutions were proposed in the literature to enhance Range Expansion technique performances. In this paper, we design a new single-input multiple-output (SIMO) context-aware cognitive transceiver (CTR) that is able to switch to the best performing modem in terms of link-level throughput. On the top of conventional adaptive modulation and coding (AMC), we allow the context-aware CTR to make best selection among three different pilot-utilization modes: conventional decision-aided (DA) or pilot- assisted, non-DA (NDA) or blind, and NDA with pilot which is a newly proposed hybrid version between the DA and NDA modes. We also enable the CTR to make best selection between two different channel identification schemes: conventional least-square (LS) and newly developed maximum-likelihood (ML) estimators. Depending on whether pilot symbols can be properly exploited or not at the receiver, we further enable the CTR to make best selection among two data detection modes: coherent or differential. We note that a considerable gains reaching $48%$ and $42%$ for $5^{th}$ percentile cell-site and average cell-site throughput respectively can be achieved by using jointly our cognitive transceiver with Range Expansion technique.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"113 26","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131942493","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}
