Receiver Directed Transmission protocol (RDT) is designed to provide multichannel access using a single radio interface. RDT introduces a clever approach to support channel assignment and negotiation without relying on a control channel or time synchronisation. Protocols based on the RDT scheme normally use an extra radio interface, dual home channel or time synchronisation to overcome the expected issues in RDT, such as, hidden terminal and deafness problems. This paper demonstrates that using RDT with a single radio and single home channel it is still possible to increase the network capacity. Additionally, the paper investigates the effect of node density, mobility and number of available channels on RDT performance. NS-2 simulator is used to evaluate the proposed scheme. Simulation results confirm that using multichannel RDT scheme can effectively increase the throughput, the packet delivery ratio and reduce the delay compared to single channel protocol.","PeriodicalId":179998,"journal":{"name":"2017 Wireless Days","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132284736","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}

We first propose three channel sensing algorithms to solve the channel sensing problem including availability constraints. Then a joint channel sensing and power control scheme (JCSPCS) is proposed to solve the power control problem including quality of service (QoS) constraints. We prove that all our algorithms are probably approximately correct (PAC) algorithms that can correctly identify a bad channel with high probability. We show that our algorithms are suitable for QoS-constrained applications as they all terminate in a finite time with a finite error rate. The performance of our channel sensing algorithms and the joint channel sensing and power control scheme is shown in the simulation results.","PeriodicalId":179998,"journal":{"name":"2017 Wireless Days","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128996701","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}

Next, we develop two IP address mobility support schemes for this architecture. The proposed solutions can handle traffic redirecting and seamless IP address continuity for the nodes moving among the distributed anchor points in a resource efficient manner. Our approaches are based on the SDN (Software Defined Networking) paradigm which is also one of the most important candidate technologies to realize 5G mobile networks. We extend the NS3-LENA simulation software to implement a decentralized LTE network as well as the proposed IP mobility support schemes.

De facto simulation tools for networking research such as ns-3 are extremely powerful. However, the time to develop, execute, and analyze a meaningful simulation in these tools can be significant. In addition to the unavoidable learning curve associated with the tool itself, the developer must have significant coding skills and domain knowledge. Once development of the simulation is complete, the time required to execute the simulation can be significant. In this paper, we present a case study that focuses on the use of the Netlogo tool to explore the impact of certain parameters on a cooperative cache deployed within a vehicular network. The results of the Netlogo simulation are then compared to the results of a similar simulation developed in ns-3. Our work shows that meaningful results can be obtained using Netlogo with less investment of time at the expense of flexibility and realism when compared to ns-3. With this approach, if the results of the Netlogo based simulation look promising, a greater investment in a more powerful and accurate simulation using ns-3 can be made. Utilizing this process saves the developer time by focusing on those approaches that look promising.","PeriodicalId":179998,"journal":{"name":"2017 Wireless Days","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126033925","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 existing protocols for DTNs have been primarily designed and analyzed under the assumption that data traffic is either Constant Bit Rate (CBR) or Poisson. It has been observed that such models are incapable of capturing the inter-arrival behavior of the present day traffic which may be bursty in nature. The traffic characteristics in todays communication networks are statistically self-similar in nature, i.e., burstiness and correlation exists over many time scales, also referred to as Long Range Dependency (LRD). In this paper we analyze the traffic characteristics in the nodes of a delay tolerant network. Self-similar traffic is generated by implementing a traffic model in the source module of DTN. It is based on the model of aggregated ON/OFF sources. A mathematical analysis is provided to elucidate the cause of self similar nature of traffic in DTN. Through simulations and statistical analysis of the traffic data, we study the degree of self-similarity of traffic in the nodes of a vehicular delay tolerant network.","PeriodicalId":179998,"journal":{"name":"2017 Wireless Days","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117157933","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}

Although the cellular networks share their own spectrum with the D2D underlay network, both of them may not belong to the same service provider. Thus, the D2D transmitter charges for the energy services released by the hybrid BS. We formulate two Stackelberg game formulations to exploit the hierarchical interaction between the BS and the D2D transmitter with/without energy trading. The associated Stackelberg equilibriums of the formulated games are derived in terms of closed-form solutions.
