In order to provide a secure communication in VANETs, a key requirement is to enable receivers to authenticate received messages while preserving the privacy of the identities of sending vehicles. However, if a misbehavior takes place, involved vehicles should be identified and evicted from the network. To this end, we proposed in a previous work [1] a ticket-based authentication scheme for VANETs preserving privacy, in which vehicles use temporary tickets to communicate with other vehicles in the network while conditionally maintaining their privacy. A vehicle’s ticket is formed through two stages: an offline stage and an online stage. Besides, the ticket should be updated whenever its vehicle enters into a new domain (containing few Road Side Units), and modified whenever its validity period expires. In this paper, we propose an optimization of that previously proposed work in order to decrease the cryptographic delay. In fact, the Identity Based Online/Offline Signature (IBOOS) technique and Shamir’s trick are introduced, already verified tickets are stored by receiving vehicles for reference later and the signature size is reduced.","PeriodicalId":177399,"journal":{"name":"2018 Seventh International Conference on Communications and Networking (ComNet)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124479712","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}

Ultra dense network (UDN) refers to the idea of densifying the cellular networks, which reduces the distance between the access nodes and the users, achieving the highest possible transmission rates and enhancing the quality of service (QoS). In this paper, we develop a joint power allocation and relay selection based on multi-hop relay in H-UDN using a low computational complexity iterative water-filling. The simulation results shows that our proposed algorithm can achieve the optimal power allocation and improve the performances of the system in term of coverage, capacity among other architectures.","PeriodicalId":177399,"journal":{"name":"2018 Seventh International Conference on Communications and Networking (ComNet)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127668292","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 investigate throughput maximization via optimized energy allocation and Automatic Repeat reQuest (ARQ) retransmission protocol. Using default energy allocation showed an inefficiency in average consumed energy throughout all retransmission attempts carried out to succeed an error-free packet reception. To overcome this limitation, we here suggest a judicious allotment of the available energy budget along transmission attempts (first transmission and potential retransmission) while keeping the total energy cost steady for each transmitted packet. For a given Signal to Noise Ratio (SNR), the optimal distribution of total available energy along all transmission attempts is determined through a Genetic Algorithm based search that exploits the throughput efficiency as a fitness function. Numerical results demonstrate the efficiency of the proposed strategy in terms of maximizing the average throughput efficiency and accordingly reveal the improvement in reducing the probability of packet erasure as well as the number of required transmissions to achieve high throughput.","PeriodicalId":177399,"journal":{"name":"2018 Seventh International Conference on Communications and Networking (ComNet)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122213352","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 C-RAN is based on the idea of splitting the conventional eNB into two parts: the Remote Radio Head (RRH) and the Base Band Unit (BBU). The RRH will be responsible for the RF transmission and it will be densified to enhance the capacity of the network and the quality of service in response to the ever-increasing high demand for the applications. The BBU will care about the computational processing. To reduce the installation and maintenance costs and to enable and improve advanced features of the network such as Coordinated Multi-Point (CoMP) and enhanced Inter-Cell Interference Coordination (e-ICIC), the RRHs should be pooled and grouped into clusters. Several RRHs will be assigned to one BBU which will break with the conventional one-to-one mapping. The Clustering task is considered to be an NP-Hard problem. This article surveys the literature on Clustering algorithms and techniques as they apply to C-RAN Architecture and evaluate the resulting configuration of BBU pools.","PeriodicalId":177399,"journal":{"name":"2018 Seventh International Conference on Communications and Networking (ComNet)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114505037","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}
