To provide energy savings, sleep modes are adopted at the Base Stations (BSs). We propose two switch-off strategies that are based either on the cell load or the BS coverage overlap. Our results show that energy savings between 10% and 30% can be achieved also for the deployment already planned to be energy-efficient, while even higher savings are achievable with the other deployments. Moreover, we find that both the proposed switch-off strategies obtain similar results, suggesting that the order at which the BSs are switched-off, and the set of BSs selected to be switched off, do not change significantly the average estimation of potential energy savings. Furthermore, on a realistic case study, comparisons are made between the results obtained by using deterministic channel estimation models and empirical formulations.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124864052","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, such solutions for MANETs have seen limited use. This paper introduces a specification-based detection engine that is built upon the functionality and limitations of the 802.11 MAC protocol, expanding the detection range of such engines in MANETs. The proposed detection engine is deployed at each node and performs detection using a set of specifications, which describe the correct operation of the MAC protocol operating at the host node. The proposed engine introduces a number of significant advantages since it can effectively detect both known and unknown attacks in real time and with minimum overhead. Moreover, it is resilient to the dynamic topologies that are common in MANETs and its deployment requires no protocol modifications.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133206353","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}

This setup is also referred to as frequency division duplex. However, such a setup makes it difficult to apply contention-based protocols like those standardized by IEEE 802.11, because they were designed so that downlink and uplink share the same frequency channel. Yet the simplicity of the 802.11 protocol and its decentralized operation make it attractive for smart grid and consumer electronics applications using TV white space or licensed spectrum. Therefore we investigate a contention-based 802.11-like protocol for paired spectrum. We leverage its downlink-uplink separation into a protocol design that combines contention-based distributed medium access with a managed reaction to packet collisions. We also demonstrate why this paired spectrum approach is relevant and desirable for TV white space secondary spectrum access. The main advantages of this protocol are (1) enabling the usage of simple and low cost contention-based 802.11-like devices in paired spectrum, (2) providing collision detection management in the uplink, and (3) an inherent resource reservation for downlink traffic. The evaluation results confirm the validity of the proposed protocol design and demonstrate the benefits obtained from collision detection management.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116586990","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 evaluate the power reduction and wake up time of different sleep modes and apply them to the model in order to evaluate the influence of the power consumption of the mobile access network.

For infotainment services data dissemination starts from a Road Side Unit (RSU) and propagates to a multiplicity of On Board Units (OBU). A RSU typically can reach with a single hop only a fraction of the interested vehicles. Multi-hop, inter-vehicle communications is necessary to reach vehicles in the whole area that could be interested in the service. For an efficient data dissemination both the number of forwarding vehicles and the number of not covered ones shall be kept down. In this work we study the extension of the RSU coverage area via a simple data dissemination defined for urban scenarios. The proposed forwarding algorithm relies only on information local to the forwarding OBU. We show that in our case studies representing urban structures the protocol guarantees a good RSU coverage extension (in the order of 20 times the transmission area of the RSU) with a very low percentage of vehicles not reached by the disseminated data.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128010703","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}

Opportunistic networking would be used as a networking paradigm towards this direction. Specifically, operator-governed opportunistic networks (ONs) are dynamically created, temporary, coordinated extensions of the infrastructure. Operator governance is being realized through the use of Cognitive Management Systems (CMSs) which acquire the context, policies and profiles of the environment and make decisions on the creation, maintenance or termination of opportunistic networks. This work presents an approach for elaborating on the concept of the management of opportunistic networks through cognitive functionalities. Two main CMSs are proposed namely, the Cognitive management System for the Coordination of the infrastructure (CSCI) and the Cognitive system for the Management of the Opportunistic Network (CMON). CSCIs and CMONs are making use of the common components of CMSs, i.e., the acquisition of context, policies and profiles, decision making, enforcement and learning and are used in order to manage the creation, maintenance and termination of an ON.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122514523","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}

Our approach extends previous work by considering the level of cooperation between BSs in the utility functions. We first address the problem of association of mobile terminals to the BSs, which determines the cell partition. This is studied in a non-cooperative context where, given a BSs placement, each mobile connects to the BS that provides it with the best signal to interference and noise ratio (SINR) - i.e., mobiles compete to achieve a better SINR. Then we consider the problem of determining the optimal locations of the BSs, taking into account the association behavior of the mobiles that will be induced by the location decisions. We study the problem in the general setting of a parametrized level of cooperation between BSs, showing the corresponding parametric utility functions and the resulting symmetric Nash equilibrium for the hierarchical Stackelberg-like problem.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124157231","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}

Jamming is a type of Denial of Service (DoS), in which the attacker tries to block the communication by interfering with the radio signals. Among the DoS attacks, jamming is very simple to achieve and very hard to eliminate. In this paper, we present POWJAM (POWer reaction system against JAMming attacks), a system to react at jamming attacks in wireless ad hoc networks. The basic idea of POWJAM is to hide the communication from a reactive jammer through changing the transmission power. In normal 802.11 ad hoc networks, if a node A wants to communicate with its neighbors it uses a direct link. However, in POWJAM, A uses a path, in which the jammer cannot hear the communication on this path. By means of simulation, the POWJAM system is evaluated. Results show the effectiveness of POWJAM to defend against reactive jammers.","PeriodicalId":309036,"journal":{"name":"2012 9th Annual Conference on Wireless On-Demand Network Systems and Services (WONS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123751479","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}
