These networks are easily prone to security attacks, since once deployed these networks are unattended and unprotected. Some of the inherent features like limited battery and low memory makes sensor networks infeasible to use conventional security solutions, which needs complex computations and high memory. There are lot of attacks on these networks which can be classified as routing attacks and data traffic attacks. Some of the data attacks in sensor nodes are wormhole, black hole and selective forwarding attack. In a black hole attack, compromised node drops all the packets forwarding through it. A special case of black hole attack is selective forwarding attack, where compromised node drops packets selectively, which may deteriorate the network efficiency. In this paper, we discussed about selective forwarding attack and some of the mitigation schemes to defend this attack.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"83 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128650423","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 request is accommodated by the target femtocell if there is any idle traffic channel in the cell. We investigate the several wireless system perimeters such as blocking probability of calls, force termination probability of calls for this model.

Along with increasing the operating frequency, there are various factors like chip size, circuit density, complexity, cost and delay which make interconnects an important issue that has to be considered while designing ICs. At GHz frequencies, long interconnect wires exhibit transmission line behaviour and also traditional lumped and distributed RC models of interconnects are no longer accurate and result in substantial errors in predicting delay and crosstalk. Therefore, a RLC circuit model of interconnects is consider in this work, which takes into account the effects inductance also. Two coupled interconnects are used to show the effects of both capacitive and inductive coupling. The coupled circuit model is studied in terms of S-parameters namely, S11 and S21, which gives return loss and insertion loss, respectively. The proposed circuit model is simulated by using the Advanced Design System 2005A (ADS) by Agilent Technologies. These parameters are obtained for different cases considering both types of coupling collectively and individually.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116050472","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 sensor nodes adhered to the human body form a network and transmit the collected data to the medical server at a remote location via internet thus forming a Wireless Body Area Network (WBAN).

At the same time, the local interconnect delays improve because the physical size of the circuit blocks decrease and the local interconnect spans shorter distances. On the other hand, the global interconnect delay increases with the technology scaling. Multiple design criteria are considered during the interconnect design process, such as delay, power, bandwidth and noise. Performance of any VLSI circuit depends on the bandwidth, as it decreases with the increase in the length of interconnects. Depending on the frequency range of operation, on-chip interconnect can be modelled as lumped and/or distributed RC line for low frequency and as a distributed RLC segments for high frequency. At even higher frequency, of the order of above 10GHz, the shunt conductance needs to be considered for accurate interconnect modelling. In this paper, on-chip interconnect has been modelled as distributed RLCG transmission lines, based on which a crosstalk aware bandwidth estimation method has been proposed in the transform domain in the presence of both inductive as well as capacitive coupling. First, the amount of crosstalk noise that would be induced on the victim line due to the transiting aggressor line has been analytically derived and then from the crosstalk noise voltage, a closed form expression for bandwidth has been proposed for distributed RLCG VLSI interconnects. The calculated bandwidth has been compared with the results obtained from that of SPICE simulation. The simulation shows that the proposed model could result an average error of as low as 15% when compared to the SPICE simulation.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125492872","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}
