Jamming attack is detected by tracking RSSI and PDR at the receiver. By varying several parameters at the sender such as power level, packet size, distance from the jammer etc., various jamming mitigation methods are explored and the results presented along with theoretical analysis.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"39 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":"130795760","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 such networks, each node acts both as a host node and a network infrastructure. Because, on one hand it sends its own data, and on the other hand it forwards other node's packets. In this paper, instead of traditional network, we consider a network of rational nodes, that is, in this network each node itself can decide whether to cooperate with its neighbors or not. Since, for each node, directing other node's packets cause to spend cost, logical nodes are reluctant to drive data packets for other nodes. Thus, we have decided to model and analyze the collaboration among nodes by using game theory. We have also tried to represent a strategy in which nodes are encouraged to cooperate with each other.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"205 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":"114201026","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 clients can call among themselves even if they are registered on two different asterisk servers, if the servers are connected through IAX protocol. The gateway is used to route VoIP calls on to the PSTN network (GSM as well as landline) and vice-versa. 4-port FXO/FXS card is used for implementing PSTN gateway while a Bluetooth enabled mobile phone compatible with asterisk server is used to implement the GSM gateway.

Thus, it is very important to track the location of firefighters in a real fire scenario, so as to alert the fire crew chief during a medical emergency. In this paper, we use Wireless Body Area Sensor Networks (WBASN) to gather various physiological data from monitoring devices and constantly monitor the firefighters in training or in action. A fire disaster is also a source of potentially hazardous gases. Therefore, systems should be developed that can monitor the level of such gases in the vicinity of the firefighters and generate appropriate alarms if levels of such gases exceed the prescribed safe levels. We also propose to set up wireless sensor devices to monitor the mobility of the firefighters inside the crisis area by measuring the Received Signal Strength Indicator (RSSI) values received by these sensor motes strategically placed at different locations. We propose to develop a comprehensive location and monitoring system to be used by the firefighters while fighting fires. Our system would be ad-hoc, thus enabling it to be setup fairly quickly.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"5 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":"115482606","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}

Here we put results of different approaches of wavelet based image denoising methods. To find best method for image denoising is still a valid challenge at the crossing of functional analysis and statistics. Here we extend the existing technique and providing a comprehensive evaluation of the proposed method. Here the results based on various types of noise, such as Gaussian, Poisson's, Salt and Pepper, and Speckle performed in this paper. SNR (signal to noise ratio) and mean square error (MSE) are as a measure of the quality of denoising was preferred.

Consistent communication in vehicular ad-hoc networks is important to provide functional and reliable traffic safety and efficiency applications. Security is the major issue in the network due to the mobile nature of the vehicle. In this paper we proposed the novel traffic congestion detection and removal scheme against DDOS attack Here the attacker behavior is broadcast the huge numbers of false information packets in network i.e. the false information about the traffic. The number of nodes or vehicles that receives the false packet information are affected from attack are called Node. Now if the traffic is jammed or congestion occurring and their information goes to Roadside Unit (RSU) then RSU must be detected and excluded permanently from the network after applying proposed effective approach. Proposed scheme against DDOS attack aims to identify and exclude attackers from the network. In the presence of misbehaving in network the false information is transferred in the network by that the vehicles are deciding to do the routing according to false information. Proposed security scheme recovers control information and improves the performance of VANET in the presence of an attacker.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"112 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":"127641262","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}
