We assume that the primary channel is operating in a TDMA manner. Thus, the spectrum sensing is operating in a slot-by-slot basis. A HMM is used for studying the cooperative spectrum sensing. In contrast to the conventional Bayesian update using only one observation in update, in this work, we propose to perform a recursive update with the observations from all the secondary users (SUs). In the proposed HMM scheme, a predefined threshold on the belief is used for determining the channel activity. With the threshold, the proposed HMM scheme is more flexible in the system operation than the simple majority vote scheme, in which no such threshold is available. We compare, by simulations, the performance of the proposed HMM scheme to that of the majority vote scheme and show that the probabilities of correctly detecting a busy state and an idle state are about 1 as the number of SUs is as large as 15, so the effects of further increase in the number of SUs are limited.","PeriodicalId":193597,"journal":{"name":"2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)","volume":"249 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114328958","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}

Javaid, Muhammad Zain-ul-Abidin, Mudassir Ejaz, Muhammad, Usman Shakeel","doi":"10.1109/BWCCA.2015.85","DOIUrl":"https://doi.org/10.1109/BWCCA.2015.85","url":null,"abstract":"From few past years, researchers are attracted towards the unexplored region of earth due to is extreme usefulness and that region is water. As we know 70 % of earth surface is water and only 30 % is land that is already explored well. Due to the presence of useful resources in acoustic environment, researchers felt the need to explore the unexplored world of water. In order to explore the acoustic environment, many Underwater Wireless Sensor Network (UWSNs) routing protocols are already proposed. In UWSNs, small sensing nodes are deployed to monitor the desired area and mostly sinks (to gather information from nodes) are deployed on top of the water surface. But the sensing nodes in UWSNs posses limited battery for its operation. Due to harsh environmental conditions of acoustic life, it is impossible to replace or recharge the battery of nodes. Hence, energy is the main constraint in UWSNs. For this purpose, many energy efficient routing protocols are proposed, but it cannot completely solve the issue. In this paper we have proposed the energy balanced and interference avoidance technique due to which the network lifetime and through put increases. In EB-IAEEDBR we introduce the concept of energy balancing. The initial energy of all the nodes is divided into energy chunks, when the energy garde falls it informs its neighbor node about energy degradation by broadcasting the control packet. The node on receiving the control packet changes its transmission mode from multi hop to direct transmission mode as initially nodes are on multi-hop transmission mode. By this mechanism, energy consumption of node is evenly distributed in the entire network, results in better network lifetime, throughput and efficient energy consumption of nodes.","PeriodicalId":193597,"journal":{"name":"2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126008428","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 mobility patterns of vehicles are generated by means of SUMO (Simulation of Urban MObility) and as communication protocol simulator is used ONE (Opportunistic Network Environment). For the simulations, we used IEEE 802.11p standard and TwoRayGround Propagation Loss Model. We use Packet Delivery Ratio (PDR), Relay Delivery Ratio (RDR), hop count and delay as evaluation metrics. We compared the performance of three protocols and the simulation results show that for PDR the Prophet protocol has better performance than other protocols. Considering RDR, the performance of First Contact and Spray-and-Wait protocols is better than Prophet protocol. For hop count, the performance of Spray-and-Wait protocol is better than other protocols. While for delay, the performance of Prophet protocol is better than other protocols.","PeriodicalId":193597,"journal":{"name":"2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126663861","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}
