These parameters degrade the performance of OFDM-based system as they destroy the orthogonality between sub-carriers. In this paper, we designed an estimation algorithm which is based on non data aided technique for the CFO and I/Q imbalance by taking advantage of the inherent orthogonal structure in the OFDM signal. We particularly analyze the different standards of 802.11, the wireless local area network (WLAN) that are OFDM based to evaluate the performance of this algorithm. The simulation results show the improvement of new estimator over the existing one in the presence of I/Q Imbalance.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114508323","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}

But as the channel quality degrades due to environmental effects such as fading or the primary users' reaccess of the channel, the secondary user has to vacate the channel. After that secondary user has to start restoration by searching and sensing other channels. Restoration is done with an objective of finding the best channel in shortest possible time to enhance the CR users' throughput. In this paper, we propose a multiband restoration scheme so that the throughput of the CR is increased and the number of channels to be sensed get reduced to a great extent as compared to single channel restoration scheme and the Threshold First (TF) scheme as well. In this scheme, two or more channels are sensed at a time for the implementation of restoration scheme. Simulation results are showing the improvements in throughput as well as the reduction of the number of channels to be sensed with the multiband restoration scheme.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127964312","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 propose a distributed task allocation algorithm for a multi-UAV sensor network for sensing thorium intensities in the coastal areas of India. A power-aware coordination and planning approach is used to coordinate the activities of multiple UAVs. Depending on the availability of resources in each sensing UAV unit, each UAV initiates a task-scheduling algorithm and distributes its remaining tasks dynamically to other UAVs. The control station sends control information to the UAVs and receives the sensed parameters along with the location information from each UAV. The task allocation algorithm was simulated successfully using a network of static motes. The network was more effective and efficient with the use of this task allocation algorithm, thus contributing to improved mission execution in UAV networks.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132765806","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 security frameworks (WPA, 802.11i) provide message integrity code (MIC) for maintaining the integrity and authentication for each data frame. MIC is kept in separate field in the frame and hence adds to the communication overhead. We propose a novel sequence number based scheme to reduce the MIC overhead in the WLANs. The scheme provides per frame message integrity and authentication. It requires only trivial operations like hash evaluation, XOR and addition. It does not require extra bits or extra frame for this purpose and also no change in the existing frame format is required.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131568035","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 technology reduces the complexity at base station.

The combination of GPON with RoF technology provides high capacity and high data rate solution. This paper provides characterization of RoF GPON by various simulations performed on OPTSIM software.

In semi automated architecture sensed data is forwarded to the actor and then to sink. This sensor network is used for road surveillance. There are many algorithms and protocols designed to reduce energy consumption. Because of different coordination pattern and topology dependency these algorithms and protocols cannot be used directly for road surveillance application. Our proposed STESA (Self Transmission Energy Saving Algorithm) is efficient than existing one. In this algorithm, we have used only sensors for forwarding data to sink directly so as to reduce energy consumption, packet loss and delay.

Higher spectrum sensing efficiency is needed to implement Cognitive Radio Networks. Thus cluster based topology is used to increase sensing efficiency. The secondary users are divided into groups or clusters which have a cluster head and the decision of the spectrum sensing taken by all the secondary users is controlled by these cluster heads in their respective region. This paper proposes a new optimized cluster head rotation and selection scheme. Practical environmental scenarios for mobile communication like fading and shadowing are taken into consideration.

The security has become one of the primary concerns as MANETS are being used widely. To achieve security goals like: authentication, integrity, non-repudiation, privacy, a secret key is necessary to be shared between the sender and the receiver. Some popular key exchange protocols have some demerits in case of MANETs which are due to mainly the requirement of high computational capability. In this paper, we proposed security enhancements to DSR for providing an on-demand secure routing protocol. We also proposed an algorithm to exchange shared / session key between the source and the destination during the route creation itself. For the performance evaluation, NS2 simulator have been used and comparisons are made with the basic DSR protocol. This Security Enabled DSR (SEDSR) ensures security goals and can withstand against single node compromise.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115460341","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}
