We first present a cross layer formulation and then use duality theory to decompose the joint design problem into congestion control and routing/scheduling subproblems, which interact through congestion prices. Given that the problem of scheduling with IC and under the SINR interference regime has been shown to be NP-complete, this paper develops a decentralized approach which allows links to coordinate their transmissions and therefore efficiently solving the link scheduling problem. We show that our decentralized algorithm achieves very close performance to other centralized methods (e.g., greedy maximal scheduling). We also study the performance gains that IC brings to wireless networks and we show that flows in the network achieve up to twice their rates in most instances, in comparisons with networks without interference cancellation capabilities. These gains are attributed to the capabilities of SIC in better managing the interference in the network and promoting higher spatial reuse among contending links.","PeriodicalId":163455,"journal":{"name":"Proceeding of IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks 2014","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127462418","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}

Applications coming from multiple heterogeneous sources may have very inhomogeneous periods and tolerable slacks, inducing a fragmented and inefficient duty cycle on the nodes, strongly accelerating the energy depletion process. In such a paradigm, a way to merge as much as possible the execution moments of the periodic tasks is mandatory, in order to reduce the energy overheads of frequent awakenings of system and devices. The partitioning method presented in this paper subdivides the evolution of the periodic tasks in small self-contained optimization sub-problems, which can be subsequently processed at run-time through a task-merging or a scheduling policy. The model and the related algorithm have been conceived such that the formal guarantees of global optimality are satisfied in the general case of a coverage problem, aimed at finding the sequence of system awakenings that fulfill the deadlines of each periodic task in the system. Moreover, the generality of the model makes it suitable for a variety of task-merging policies and algorithms. Experimental results demonstrate the high computational efficiency of the proposed partitioning approach.","PeriodicalId":163455,"journal":{"name":"Proceeding of IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks 2014","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116452366","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}

Indeed, devices with limited capabilities shall trade off between consuming their resources to maintain a precise view of the neighbours' link quality and to build routes almost blindly. For instance, the Routing Protocol for Low-Power and Lossy Networks (RPL), which has been recently standardised by the IETF to enable IPv6-based sensor networks, only estimates the quality of the links used to deliver data packets. However, this solution has been demonstrated to cause periods of routing instability and reduced packet delivery rates since it estimates only the quality of utilised links. To address this issue in this work we propose a lightweight link estimation procedure that exploits Trickle-based topology maintenance techniques to simultaneously estimate link qualities and propagate routing information. Our proposed scheme has been integrated in the Contiki's RPL prototype implementation. Simulation results demonstrate that our proposal is capable of measuring the quality of the links to neighbours with small overhead, which results into better routing decisions and improved packet delivery rates.","PeriodicalId":163455,"journal":{"name":"Proceeding of IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks 2014","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117291031","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}

Carrier Sense Multiple Access (CSMA) has been shown to perform sufficiently well in most situations and being able to support safety and efficiency vehicular applications. Recently, Self-organizing Time-Division Multiple Access (STDMA) is being considered as an alternative and has been shown to coordinate the channel slightly better under certain situations. However, when comparing both protocols the precise details of radio and network conditions and parametrization of the protocols are decisive on which protocol takes a slight lead. Consequently, scenarios can be constructed quite easily in which one protocol is superior over the other one. The focus of this work is thus not to absolutely compare both protocols, but rather to understand the strengths and weaknesses of both protocols in certain situations. In particular, we consider i) to which degree hidden nodes influence the coordination ability, ii) how an extended carrier sensing range is beneficial and iii) how temporary fading influences the performance of both MAC protocols. Our results show that while an extended carrier sensing range is only beneficial for CSMA, the existence and severity of fading is far less detrimental for STDMA than for CSMA.","PeriodicalId":163455,"journal":{"name":"Proceeding of IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks 2014","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121314936","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}

High availability of network controller is an urgent need objectively. The appearance of controller instance fault should not be perceived by data plane. During the fault recovery, OpenFlow messages, especially asynchronous message from data plane, should not be discarded. Otherwise the control platform would hold the outdated network status. This is an interesting problem which we call Asynchronous Message Discard (ASMD) trouble. This paper proposes a Non-stop network controller (NSNC). It can troubleshoot the ASMD problem based on highly available TCP (HA-TCP) technology. During the fault recovery on distributed control platform, we want to elect the optimal controller to take over the network devices managed by the failed controller instance. We analyses the minimum metrics set for controller election. The view of this paper is verified on Floodlight controller. Experiments show that when the controller instance fails, asynchronous messages from switch will not be discarded, and using HA-TCP only adds negligible overhead to throughput and latency. We test the performance of election algorithm based on Mininet. Currently, there is only a theoretical analysis of metrics related to the election. We will test the validity of the election strategy in a real scenario as part of our future work.","PeriodicalId":163455,"journal":{"name":"Proceeding of IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks 2014","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127917775","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}
