Since multimedia contents account for most of the network traffic, content delivery is a big issue when designing network protocols. By combining the use of both directional and omnidirectional antennas, the performance of content delivery in WMNs can be improved. Currently, research works have shown that the relationship between nodes' interests in the network reveals the small-world pattern, so we can analyze nodes' interests and design optimal mechanism to deliver contents based on their interests. In this paper, we use the interest-sharing graph to capture the similarities between nodes' interests. Based on the interesting-sharing graph, we cluster nodes in the network using graph partitioning algorithm. The purpose of clustering is to make nodes in the same cluster share similar interests. After clustering nodes, we design a content delivery mechanism in WMNs which takes advantage of both omnidirectional and directional antennas. The simulation results show that our proposed content delivery mechanism can adapt to the WMNs and performs better than using omnidirectional or directional antennas only.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134015613","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}

In this paper, we proposed a novel approach to determine the association of users, allocation of resources and the proportion of ABSFs. We formulate a system throughput maximization problem with proportional rate constraint, compared with using log-utility, which can not be utilized to adjust resource allocation, our model can help us analyze and explicitly control the resource allocation among users under different interference patterns. The difficulty of our formulated problem comes from that it is NP-hard, to overcome this challenge, we relax the integer constraint and the original problem is decomposed into two subproblems. Firstly, for a given ABSFs proportion, we obtain an insight that the optimal user association is determined by the achievable rate ratio offered by macrocell and picocell. Also, for a given association of users, we figure out the explicit expressions for the optimal resource allocation and ABSFs proportion. By exploiting the characterization of the optimal solution, we proposed a low complicity algorithm. Simulation results show the effectiveness of the proposed algorithm.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133324990","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, frequent connection reestablishments caused by OTT services which send or receive small amounts of data often lead to a heavy signalling load within the mobile networks. That has brought about signalling storm, which is a specific problem of mobile networks. It is mainly limited by the scarcity of wireless spectrum resources. Heartbeat mechanism is one of OTT services. Smartphones communicate with the mobile networks by the heartbeat mechanism to report whether they are online. Although heartbeat message belongs to small data services, it lead that users update their status frequently. The payload of update message can not be ignored. Thus, for OTT services such as Wechat, mobile QQ, the optimization of heartbeat mechanism has become one of the best methods to reduce the network payload. In this paper, we proposed a new concept visual user equipment (VUE) which can imitate some periodic information of user equipment (UE) and replace the UE to communicate with applications in the cable end. We also proposed a scheme to reduce the transmission of heartbeat signallings according to the state of OTT services. Under the same end-to-end payload condition our scheme has greater network capacity and higher throughput at the expense of a little rise in packet loss rate only when the arrival rate of service packets is high. On the other hand, our scheme can relieve the signalling storm of OTT services to a great extent.","PeriodicalId":412971,"journal":{"name":"2014 Sixth International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115393935","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}
